string issuer = 2
Identifies the principal that issued the JWT. See https://tools.ietf.org/html/draft-ietf-oauth-json-web-token-32#section-4.1.1 Usually a URL or an email address. Example: https://securetoken.google.com Example: 1234567-compute@developer.gserviceaccount.com
string jwks_uri = 3
URL of the provider's public key set to validate signature of the JWT. See [OpenID Discovery](https://openid.net/specs/openid-connect-discovery-1_0.html#ProviderMetadata). Optional if the key set document: - can be retrieved from [OpenID Discovery](https://openid.net/specs/openid-connect-discovery-1_0.html of the issuer. - can be inferred from the email domain of the issuer (e.g. a Google service account).

The list of JWT [audiences](https://tools.ietf.org/html/draft-ietf-oauth-json-web-token-32#section-4.1.3). that are allowed to access. A JWT containing any of these audiences will be accepted. When this setting is absent, only JWTs with audience "https://[Service_name][google.api.Service.name]/[API_name][google.protobuf.Api.name]" will be accepted. For example, if no audiences are in the setting, LibraryService API will only accept JWTs with the following audience "https://library-example.googleapis.com/google.example.library.v1.LibraryService".

`Distribution` contains summary statistics for a population of values. It optionally contains a histogram representing the distribution of those values across a set of buckets. The summary statistics are the count, mean, sum of the squared deviation from the mean, the minimum, and the maximum of the set of population of values. The histogram is based on a sequence of buckets and gives a count of values that fall into each bucket. The boundaries of the buckets are given either explicitly or by formulas for buckets of fixed or exponentially increasing widths. Although it is not forbidden, it is generally a bad idea to include non-finite values (infinities or NaNs) in the population of values, as this will render the `mean` and `sum_of_squared_deviation` fields meaningless.

int64 count = 1
The number of values in the population. Must be non-negative. This value must equal the sum of the values in `bucket_counts` if a histogram is provided.
double mean = 2
The arithmetic mean of the values in the population. If `count` is zero then this field must be zero.
double sum_of_squared_deviation = 3
The sum of squared deviations from the mean of the values in the population. For values x_i this is: Sum[i=1..n]((x_i - mean)^2) Knuth, "The Art of Computer Programming", Vol. 2, page 323, 3rd edition describes Welford's method for accumulating this sum in one pass. If `count` is zero then this field must be zero.
optional Distribution.Range range = 4
If specified, contains the range of the population values. The field must not be present if the `count` is zero.
optional Distribution.BucketOptions bucket_options = 6
Defines the histogram bucket boundaries. If the distribution does not contain a histogram, then omit this field.
repeated int64 bucket_counts = 7
The number of values in each bucket of the histogram, as described in `bucket_options`. If the distribution does not have a histogram, then omit this field. If there is a histogram, then the sum of the values in `bucket_counts` must equal the value in the `count` field of the distribution. If present, `bucket_counts` should contain N values, where N is the number of buckets specified in `bucket_options`. If you supply fewer than N values, the remaining values are assumed to be 0. The order of the values in `bucket_counts` follows the bucket numbering schemes described for the three bucket types. The first value must be the count for the underflow bucket (number 0). The next N-2 values are the counts for the finite buckets (number 1 through N-2). The N'th value in `bucket_counts` is the count for the overflow bucket (number N-1).
repeated Distribution.Exemplar exemplars = 10
Must be in increasing order of `value` field.

`BucketOptions` describes the bucket boundaries used to create a histogram for the distribution. The buckets can be in a linear sequence, an exponential sequence, or each bucket can be specified explicitly. `BucketOptions` does not include the number of values in each bucket. A bucket has an inclusive lower bound and exclusive upper bound for the values that are counted for that bucket. The upper bound of a bucket must be strictly greater than the lower bound. The sequence of N buckets for a distribution consists of an underflow bucket (number 0), zero or more finite buckets (number 1 through N - 2) and an overflow bucket (number N - 1). The buckets are contiguous: the lower bound of bucket i (i > 0) is the same as the upper bound of bucket i - 1. The buckets span the whole range of finite values: lower bound of the underflow bucket is -infinity and the upper bound of the overflow bucket is +infinity. The finite buckets are so-called because both bounds are finite.

Used in: Distribution

oneof options
Exactly one of these three fields must be set.
- BucketOptions.Linear linear_buckets = 1
  The linear bucket.
- BucketOptions.Exponential exponential_buckets = 2
  The exponential buckets.
- BucketOptions.Explicit explicit_buckets = 3
  The explicit buckets.

Specifies a set of buckets with arbitrary widths. There are `size(bounds) + 1` (= N) buckets. Bucket `i` has the following boundaries: Upper bound (0 <= i < N-1): bounds[i] Lower bound (1 <= i < N); bounds[i - 1] The `bounds` field must contain at least one element. If `bounds` has only one element, then there are no finite buckets, and that single element is the common boundary of the overflow and underflow buckets.

Used in: BucketOptions

repeated double bounds = 1
The values must be monotonically increasing.

Specifies an exponential sequence of buckets that have a width that is proportional to the value of the lower bound. Each bucket represents a constant relative uncertainty on a specific value in the bucket. There are `num_finite_buckets + 2` (= N) buckets. Bucket `i` has the following boundaries: Upper bound (0 <= i < N-1): scale * (growth_factor ^ i). Lower bound (1 <= i < N): scale * (growth_factor ^ (i - 1)).

int32 num_finite_buckets = 1
Must be greater than 0.
double growth_factor = 2
Must be greater than 1.
double scale = 3

`Documentation` provides the information for describing a service. Example: <pre><code>documentation: summary: > The Google Calendar API gives access to most calendar features. pages: - name: Overview content: (== include google/foo/overview.md ==) - name: Tutorial content: (== include google/foo/tutorial.md ==) subpages; - name: Java content: (== include google/foo/tutorial_java.md ==) rules: - selector: google.calendar.Calendar.Get description: > ... - selector: google.calendar.Calendar.Put description: > ... </code></pre> Documentation is provided in markdown syntax. In addition to standard markdown features, definition lists, tables and fenced code blocks are supported. Section headers can be provided and are interpreted relative to the section nesting of the context where a documentation fragment is embedded. Documentation from the IDL is merged with documentation defined via the config at normalization time, where documentation provided by config rules overrides IDL provided. A number of constructs specific to the API platform are supported in documentation text. In order to reference a proto element, the following notation can be used: <pre><code>[fully.qualified.proto.name][]</code></pre> To override the display text used for the link, this can be used: <pre><code>[display text][fully.qualified.proto.name]</code></pre> Text can be excluded from doc using the following notation: <pre><code>(-- internal comment --)</code></pre> A few directives are available in documentation. Note that directives must appear on a single line to be properly identified. The `include` directive includes a markdown file from an external source: <pre><code>(== include path/to/file ==)</code></pre> The `resource_for` directive marks a message to be the resource of a collection in REST view. If it is not specified, tools attempt to infer the resource from the operations in a collection: <pre><code>(== resource_for v1.shelves.books ==)</code></pre> The directive `suppress_warning` does not directly affect documentation and is documented together with service config validation.

string overview = 2
Declares a single overview page. For example: <pre><code>documentation: summary: ... overview: (== include overview.md ==) </code></pre> This is a shortcut for the following declaration (using pages style): <pre><code>documentation: summary: ... pages: - name: Overview content: (== include overview.md ==) </code></pre> Note: you cannot specify both `overview` field and `pages` field.

A documentation rule provides information about individual API elements.

Used in: Documentation

string selector = 1
The selector is a comma-separated list of patterns. Each pattern is a qualified name of the element which may end in "*", indicating a wildcard. Wildcards are only allowed at the end and for a whole component of the qualified name, i.e. "foo.*" is ok, but not "foo.b*" or "foo.*.bar". To specify a default for all applicable elements, the whole pattern "*" is used.

Description of the selected API(s).
string deprecation_description = 3
Deprecation description of the selected element(s). It can be provided if an element is marked as `deprecated`.

`Endpoint` describes a network endpoint that serves a set of APIs. A service may expose any number of endpoints, and all endpoints share the same service configuration, such as quota configuration and monitoring configuration. Example service configuration: name: library-example.googleapis.com endpoints: # Below entry makes 'google.example.library.v1.Library' # API be served from endpoint address library-example.googleapis.com. # It also allows HTTP OPTIONS calls to be passed to the backend, for # it to decide whether the subsequent cross-origin request is # allowed to proceed. - name: library-example.googleapis.com allow_cors: true

Used in: Service

string name = 1
The canonical name of this endpoint.
repeated string aliases = 2
DEPRECATED: This field is no longer supported. Instead of using aliases, please specify multiple [google.api.Endpoint][google.api.Endpoint] for each of the intended aliases. Additional names that this endpoint will be hosted on.
repeated string features = 4
The list of features enabled on this endpoint.
string target = 101
The specification of an Internet routable address of API frontend that will handle requests to this [API Endpoint](https://cloud.google.com/apis/design/glossary). It should be either a valid IPv4 address or a fully-qualified domain name. For example, "8.8.8.8" or "myservice.appspot.com".
bool allow_cors = 5
Allowing [CORS](https://en.wikipedia.org/wiki/Cross-origin_resource_sharing), aka cross-domain traffic, would allow the backends served from this endpoint to receive and respond to HTTP OPTIONS requests. The response will be used by the browser to determine whether the subsequent cross-origin request is allowed to proceed.

An indicator of the behavior of a given field (for example, that a field is required in requests, or given as output but ignored as input). This **does not** change the behavior in protocol buffers itself; it only denotes the behavior and may affect how API tooling handles the field. Note: This enum **may** receive new values in the future.

FIELD_BEHAVIOR_UNSPECIFIED = 0
Conventional default for enums. Do not use this.
OPTIONAL = 1
Specifically denotes a field as optional. While all fields in protocol buffers are optional, this may be specified for emphasis if appropriate.
REQUIRED = 2
Denotes a field as required. This indicates that the field **must** be provided as part of the request, and failure to do so will cause an error (usually `INVALID_ARGUMENT`).
OUTPUT_ONLY = 3
Denotes a field as output only. This indicates that the field is provided in responses, but including the field in a request does nothing (the server *must* ignore it and *must not* throw an error as a result of the field's presence).
INPUT_ONLY = 4
Denotes a field as input only. This indicates that the field is provided in requests, and the corresponding field is not included in output.
IMMUTABLE = 5
Denotes a field as immutable. This indicates that the field may be set once in a request to create a resource, but may not be changed thereafter.
UNORDERED_LIST = 6
Denotes that a (repeated) field is an unordered list. This indicates that the service may provide the elements of the list in any arbitrary order, rather than the order the user originally provided. Additionally, the list's order may or may not be stable.

Defines the HTTP configuration for an API service. It contains a list of [HttpRule][google.api.HttpRule], each specifying the mapping of an RPC method to one or more HTTP REST API methods.

Used in: Service

repeated HttpRule rules = 1
A list of HTTP configuration rules that apply to individual API methods. **NOTE:** All service configuration rules follow "last one wins" order.
bool fully_decode_reserved_expansion = 2
When set to true, URL path parmeters will be fully URI-decoded except in cases of single segment matches in reserved expansion, where "%2F" will be left encoded. The default behavior is to not decode RFC 6570 reserved characters in multi segment matches.

Message that represents an arbitrary HTTP body. It should only be used for payload formats that can't be represented as JSON, such as raw binary or an HTML page. This message can be used both in streaming and non-streaming API methods in the request as well as the response. It can be used as a top-level request field, which is convenient if one wants to extract parameters from either the URL or HTTP template into the request fields and also want access to the raw HTTP body. Example: message GetResourceRequest { // A unique request id. string request_id = 1; // The raw HTTP body is bound to this field. google.api.HttpBody http_body = 2; } service ResourceService { rpc GetResource(GetResourceRequest) returns (google.api.HttpBody); rpc UpdateResource(google.api.HttpBody) returns (google.protobuf.Empty); } Example with streaming methods: service CaldavService { rpc GetCalendar(stream google.api.HttpBody) returns (stream google.api.HttpBody); rpc UpdateCalendar(stream google.api.HttpBody) returns (stream google.api.HttpBody); } Use of this type only changes how the request and response bodies are handled, all other features will continue to work unchanged.

string content_type = 1
The HTTP Content-Type string representing the content type of the body.
bytes data = 2
HTTP body binary data.
repeated protobuf.Any extensions = 3
Application specific response metadata. Must be set in the first response for streaming APIs.

`HttpRule` defines the mapping of an RPC method to one or more HTTP REST API methods. The mapping specifies how different portions of the RPC request message are mapped to URL path, URL query parameters, and HTTP request body. The mapping is typically specified as an `google.api.http` annotation on the RPC method, see "google/api/annotations.proto" for details. The mapping consists of a field specifying the path template and method kind. The path template can refer to fields in the request message, as in the example below which describes a REST GET operation on a resource collection of messages: service Messaging { rpc GetMessage(GetMessageRequest) returns (Message) { option (google.api.http).get = "/v1/messages/{message_id}/{sub.subfield}"; } } message GetMessageRequest { message SubMessage { string subfield = 1; } string message_id = 1; // mapped to the URL SubMessage sub = 2; // `sub.subfield` is url-mapped } message Message { string text = 1; // content of the resource } The same http annotation can alternatively be expressed inside the `GRPC API Configuration` YAML file. http: rules: - selector: <proto_package_name>.Messaging.GetMessage get: /v1/messages/{message_id}/{sub.subfield} This definition enables an automatic, bidrectional mapping of HTTP JSON to RPC. Example: HTTP | RPC -----|----- `GET /v1/messages/123456/foo` | `GetMessage(message_id: "123456" sub: SubMessage(subfield: "foo"))` In general, not only fields but also field paths can be referenced from a path pattern. Fields mapped to the path pattern cannot be repeated and must have a primitive (non-message) type. Any fields in the request message which are not bound by the path pattern automatically become (optional) HTTP query parameters. Assume the following definition of the request message: service Messaging { rpc GetMessage(GetMessageRequest) returns (Message) { option (google.api.http).get = "/v1/messages/{message_id}"; } } message GetMessageRequest { message SubMessage { string subfield = 1; } string message_id = 1; // mapped to the URL int64 revision = 2; // becomes a parameter SubMessage sub = 3; // `sub.subfield` becomes a parameter } This enables a HTTP JSON to RPC mapping as below: HTTP | RPC -----|----- `GET /v1/messages/123456?revision=2&sub.subfield=foo` | `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield: "foo"))` Note that fields which are mapped to HTTP parameters must have a primitive type or a repeated primitive type. Message types are not allowed. In the case of a repeated type, the parameter can be repeated in the URL, as in `...?param=A&param=B`. For HTTP method kinds which allow a request body, the `body` field specifies the mapping. Consider a REST update method on the message resource collection: service Messaging { rpc UpdateMessage(UpdateMessageRequest) returns (Message) { option (google.api.http) = { put: "/v1/messages/{message_id}" body: "message" }; } } message UpdateMessageRequest { string message_id = 1; // mapped to the URL Message message = 2; // mapped to the body } The following HTTP JSON to RPC mapping is enabled, where the representation of the JSON in the request body is determined by protos JSON encoding: HTTP | RPC -----|----- `PUT /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id: "123456" message { text: "Hi!" })` The special name `*` can be used in the body mapping to define that every field not bound by the path template should be mapped to the request body. This enables the following alternative definition of the update method: service Messaging { rpc UpdateMessage(Message) returns (Message) { option (google.api.http) = { put: "/v1/messages/{message_id}" body: "*" }; } } message Message { string message_id = 1; string text = 2; } The following HTTP JSON to RPC mapping is enabled: HTTP | RPC -----|----- `PUT /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id: "123456" text: "Hi!")` Note that when using `*` in the body mapping, it is not possible to have HTTP parameters, as all fields not bound by the path end in the body. This makes this option more rarely used in practice of defining REST APIs. The common usage of `*` is in custom methods which don't use the URL at all for transferring data. It is possible to define multiple HTTP methods for one RPC by using the `additional_bindings` option. Example: service Messaging { rpc GetMessage(GetMessageRequest) returns (Message) { option (google.api.http) = { get: "/v1/messages/{message_id}" additional_bindings { get: "/v1/users/{user_id}/messages/{message_id}" } }; } } message GetMessageRequest { string message_id = 1; string user_id = 2; } This enables the following two alternative HTTP JSON to RPC mappings: HTTP | RPC -----|----- `GET /v1/messages/123456` | `GetMessage(message_id: "123456")` `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id: "123456")` # Rules for HTTP mapping The rules for mapping HTTP path, query parameters, and body fields to the request message are as follows: 1. The `body` field specifies either `*` or a field path, or is omitted. If omitted, it indicates there is no HTTP request body. 2. Leaf fields (recursive expansion of nested messages in the request) can be classified into three types: (a) Matched in the URL template. (b) Covered by body (if body is `*`, everything except (a) fields; else everything under the body field) (c) All other fields. 3. URL query parameters found in the HTTP request are mapped to (c) fields. 4. Any body sent with an HTTP request can contain only (b) fields. The syntax of the path template is as follows: Template = "/" Segments [ Verb ] ; Segments = Segment { "/" Segment } ; Segment = "*" | "**" | LITERAL | Variable ; Variable = "{" FieldPath [ "=" Segments ] "}" ; FieldPath = IDENT { "." IDENT } ; Verb = ":" LITERAL ; The syntax `*` matches a single path segment. The syntax `**` matches zero or more path segments, which must be the last part of the path except the `Verb`. The syntax `LITERAL` matches literal text in the path. The syntax `Variable` matches part of the URL path as specified by its template. A variable template must not contain other variables. If a variable matches a single path segment, its template may be omitted, e.g. `{var}` is equivalent to `{var=*}`. If a variable contains exactly one path segment, such as `"{var}"` or `"{var=*}"`, when such a variable is expanded into a URL path, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. Such variables show up in the Discovery Document as `{var}`. If a variable contains one or more path segments, such as `"{var=foo/*}"` or `"{var=**}"`, when such a variable is expanded into a URL path, all characters except `[-_.~/0-9a-zA-Z]` are percent-encoded. Such variables show up in the Discovery Document as `{+var}`. NOTE: While the single segment variable matches the semantics of [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String Expansion, the multi segment variable **does not** match RFC 6570 Reserved Expansion. The reason is that the Reserved Expansion does not expand special characters like `?` and `#`, which would lead to invalid URLs. NOTE: the field paths in variables and in the `body` must not refer to repeated fields or map fields.

Component } { "/" Component } ; Component = ( [ PREFIX ] UNIT | "%" ) [ Annotation ] | Annotation | "1" ; Annotation = "{" NAME "}" ; Notes: * `Annotation` is just a comment if it follows a `UNIT` and is equivalent to `1` if it is used alone. For examples, `{requests}/s == 1/s`, `By{transmitted}/s == By/s`. * `NAME` is a sequence of non-blank printable ASCII characters not containing '{' or '}'. * `1` represents dimensionless value 1, such as in `1/s`. * `%` represents dimensionless value 1/100, and annotates values giving a percentage.

An object representing a resource that can be used for monitoring, logging, billing, or other purposes. Examples include virtual machine instances, databases, and storage devices such as disks. The `type` field identifies a [MonitoredResourceDescriptor][google.api.MonitoredResourceDescriptor] object that describes the resource's schema. Information in the `labels` field identifies the actual resource and its attributes according to the schema. For example, a particular Compute Engine VM instance could be represented by the following object, because the [MonitoredResourceDescriptor][google.api.MonitoredResourceDescriptor] for `"gce_instance"` has labels `"instance_id"` and `"zone"`: { "type": "gce_instance", "labels": { "instance_id": "12345678901234", "zone": "us-central1-a" }}

string type = 1

Stackdriver determines what system labels are useful and how to obtain their values. Some examples: "machine_image", "vpc", "subnet_id", "security_group", "name", etc. System label values can be only strings, Boolean values, or a list of strings. For example: { "name": "my-test-instance", "security_group": ["a", "b", "c"], "spot_instance": false }
map<string, string> user_labels = 2
Output only. A map of user-defined metadata labels.

Monitoring configuration of the service. The example below shows how to configure monitored resources and metrics for monitoring. In the example, a monitored resource and two metrics are defined.

OAuth scopes are a way to define data and permissions on data. For example, there are scopes defined for "Read-only access to Google Calendar" and "Access to Cloud Platform". Users can consent to a scope for an application, giving it permission to access that data on their behalf. OAuth scope specifications should be fairly coarse grained; a user will need to see and understand the text description of what your scope means. In most cases: use one or at most two OAuth scopes for an entire family of products. If your product has multiple APIs, you should probably be sharing the OAuth scope across all of those APIs. When you need finer grained OAuth consent screens: talk with your product management about how developers will use them in practice. Please note that even though each of the canonical scopes is enough for a request to be accepted and passed to the backend, a request can still fail due to the backend requiring additional scopes or permissions.

Used in: AuthenticationRule

string canonical_scopes = 1
The list of publicly documented OAuth scopes that are allowed access. An OAuth token containing any of these scopes will be accepted. Example: canonical_scopes: https://www.googleapis.com/auth/calendar, https://www.googleapis.com/auth/calendar.read

A descriptor for defining project properties for a service. One service may have many consumer projects, and the service may want to behave differently depending on some properties on the project. For example, a project may be associated with a school, or a business, or a government agency, a business type property on the project may affect how a service responds to the client. This descriptor defines which properties are allowed to be set on a project. Example: project_properties: properties: - name: NO_WATERMARK type: BOOL description: Allows usage of the API without watermarks. - name: EXTENDED_TILE_CACHE_PERIOD type: INT64

repeated Property properties = 1
List of per consumer project-specific properties.

Defines project properties. API services can define properties that can be assigned to consumer projects so that backends can perform response customization without having to make additional calls or maintain additional storage. For example, Maps API defines properties that controls map tile cache period, or whether to embed a watermark in a result. These values can be set via API producer console. Only API providers can define and set these properties.

Quota configuration helps to achieve fairness and budgeting in service usage. The quota configuration works this way: - The service configuration defines a set of metrics. - For API calls, the quota.metric_rules maps methods to metrics with corresponding costs. - The quota.limits defines limits on the metrics, which will be used for quota checks at runtime. An example quota configuration in yaml format: quota: limits: - name: apiWriteQpsPerProject metric: library.googleapis.com/write_calls unit: "1/min/{project}" # rate limit for consumer projects values: STANDARD: 10000 # The metric rules bind all methods to the read_calls metric, # except for the UpdateBook and DeleteBook methods. These two methods # are mapped to the write_calls metric, with the UpdateBook method # consuming at twice rate as the DeleteBook method. metric_rules: - selector: "*" metric_costs: library.googleapis.com/read_calls: 1 - selector: google.example.library.v1.LibraryService.UpdateBook metric_costs: library.googleapis.com/write_calls: 2 - selector: google.example.library.v1.LibraryService.DeleteBook metric_costs: library.googleapis.com/write_calls: 1 Corresponding Metric definition: metrics: - name: library.googleapis.com/read_calls display_name: Read requests metric_kind: DELTA value_type: INT64 - name: library.googleapis.com/write_calls display_name: Write requests metric_kind: DELTA value_type: INT64

repeated QuotaLimit limits = 3
List of `QuotaLimit` definitions for the service. Used by metric-based quotas only.
repeated MetricRule metric_rules = 4
List of `MetricRule` definitions, each one mapping a selected method to one or more metrics. Used by metric-based quotas only.

`QuotaLimit` defines a specific limit that applies over a specified duration for a limit type. There can be at most one limit for a duration and limit type combination defined within a `QuotaGroup`.

Used in: Quota

string name = 6
Name of the quota limit. The name is used to refer to the limit when overriding the default limit on per-consumer basis. For group-based quota limits, the name must be unique within the quota group. If a name is not provided, it will be generated from the limit_by and duration fields. For metric-based quota limits, the name must be provided, and it must be unique within the service. The name can only include alphanumeric characters as well as '-'. The maximum length of the limit name is 64 characters. The name of a limit is used as a unique identifier for this limit. Therefore, once a limit has been put into use, its name should be immutable. You can use the display_name field to provide a user-friendly name for the limit. The display name can be evolved over time without affecting the identity of the limit.
string description = 2
Optional. User-visible, extended description for this quota limit. Should be used only when more context is needed to understand this limit than provided by the limit's display name (see: `display_name`).
int64 default_limit = 3
Default number of tokens that can be consumed during the specified duration. This is the number of tokens assigned when a client application developer activates the service for his/her project. Specifying a value of 0 will block all requests. This can be used if you are provisioning quota to selected consumers and blocking others. Similarly, a value of -1 will indicate an unlimited quota. No other negative values are allowed. Used by group-based quotas only.
int64 max_limit = 4
Maximum number of tokens that can be consumed during the specified duration. Client application developers can override the default limit up to this maximum. If specified, this value cannot be set to a value less than the default limit. If not specified, it is set to the default limit. To allow clients to apply overrides with no upper bound, set this to -1, indicating unlimited maximum quota. Used by group-based quotas only.
int64 free_tier = 7
Free tier value displayed in the Developers Console for this limit. The free tier is the number of tokens that will be subtracted from the billed amount when billing is enabled. This field can only be set on a limit with duration "1d", in a billable group; it is invalid on any other limit. If this field is not set, it defaults to 0, indicating that there is no free tier for this service. Used by group-based quotas only.
string duration = 5
Duration of this limit in textual notation. Example: "100s", "24h", "1d". For duration longer than a day, only multiple of days is supported. We support only "100s" and "1d" for now. Additional support will be added in the future. "0" indicates indefinite duration. Used by group-based quotas only.
string metric = 8
The name of the metric this quota limit applies to. The quota limits with the same metric will be checked together during runtime. The metric must be defined within the service config. Used by metric-based quotas only.
string unit = 9
Specify the unit of the quota limit. It uses the same syntax as [Metric.unit][]. The supported unit kinds are determined by the quota backend system. The [Google Service Control](https://cloud.google.com/service-control) supports the following unit components: * One of the time intevals: * "/min" for quota every minute. * "/d" for quota every 24 hours, starting 00:00 US Pacific Time. * Otherwise the quota won't be reset by time, such as storage limit. * One and only one of the granted containers: * "/{organization}" quota for an organization. * "/{project}" quota for a project. * "/{folder}" quota for a folder. * "/{resource}" quota for a universal resource. * Zero or more quota segmentation dimension. Not all combos are valid. * "/{region}" quota for every region. Not to be used with time intervals. * Otherwise the resources granted on the target is not segmented. * "/{zone}" quota for every zone. Not to be used with time intervals. * Otherwise the resources granted on the target is not segmented. * "/{resource}" quota for a resource associated with a project or org. Here are some examples: * "1/min/{project}" for quota per minute per project. * "1/min/{user}" for quota per minute per user. * "1/min/{organization}" for quota per minute per organization. Note: the order of unit components is insignificant. The "1" at the beginning is required to follow the metric unit syntax. Used by metric-based quotas only.
map<string, int64> values = 10
Tiered limit values. Also allows for regional or zone overrides for these values if "/{region}" or "/{zone}" is specified in the unit field. Currently supported tiers from low to high: VERY_LOW, LOW, STANDARD, HIGH, VERY_HIGH To apply different limit values for users according to their tiers, specify the values for the tiers you want to differentiate. For example: {LOW:100, STANDARD:500, HIGH:1000, VERY_HIGH:5000} The limit value for each tier is optional except for the tier STANDARD. The limit value for an unspecified tier falls to the value of its next tier towards tier STANDARD. For the above example, the limit value for tier STANDARD is 500. To apply the same limit value for all users, just specify limit value for tier STANDARD. For example: {STANDARD:500}. To apply a regional overide for a tier, add a map entry with key "<TIER>/<region>", where <region> is a region name. Similarly, for a zone override, add a map entry with key "<TIER>/{zone}". Further, a wildcard can be used at the end of a zone name in order to specify zone level overrides. For example: LOW: 10, STANDARD: 50, HIGH: 100, LOW/us-central1: 20, STANDARD/us-central1: 60, HIGH/us-central1: 200, LOW/us-central1-*: 10, STANDARD/us-central1-*: 20, HIGH/us-central1-*: 80 The regional overrides tier set for each region must be the same as the tier set for default limit values. Same rule applies for zone overrides tier as well. Used by metric-based quotas only.
string display_name = 12
User-visible display name for this limit. Optional. If not set, the UI will provide a default display name based on the quota configuration. This field can be used to override the default display name generated from the configuration.

A simple descriptor of a resource type. ResourceDescriptor annotates a resource message (either by means of a protobuf annotation or use in the service config), and associates the resource's schema, the resource type, and the pattern of the resource name. Example: message Topic { // Indicates this message defines a resource schema. // Declares the resource type in the format of {service}/{kind}. // For Kubernetes resources, the format is {api group}/{kind}. option (google.api.resource) = { type: "pubsub.googleapis.com/Topic" name_descriptor: { pattern: "projects/{project}/topics/{topic}" parent_type: "cloudresourcemanager.googleapis.com/Project" parent_name_extractor: "projects/{project}" } }; } The ResourceDescriptor Yaml config will look like: resources: - type: "pubsub.googleapis.com/Topic" name_descriptor: - pattern: "projects/{project}/topics/{topic}" parent_type: "cloudresourcemanager.googleapis.com/Project" parent_name_extractor: "projects/{project}" Sometimes, resources have multiple patterns, typically because they can live under multiple parents. Example: message LogEntry { option (google.api.resource) = { type: "logging.googleapis.com/LogEntry" name_descriptor: { pattern: "projects/{project}/logs/{log}" parent_type: "cloudresourcemanager.googleapis.com/Project" parent_name_extractor: "projects/{project}" } name_descriptor: { pattern: "folders/{folder}/logs/{log}" parent_type: "cloudresourcemanager.googleapis.com/Folder" parent_name_extractor: "folders/{folder}" } name_descriptor: { pattern: "organizations/{organization}/logs/{log}" parent_type: "cloudresourcemanager.googleapis.com/Organization" parent_name_extractor: "organizations/{organization}" } name_descriptor: { pattern: "billingAccounts/{billing_account}/logs/{log}" parent_type: "billing.googleapis.com/BillingAccount" parent_name_extractor: "billingAccounts/{billing_account}" } }; } The ResourceDescriptor Yaml config will look like: resources: - type: 'logging.googleapis.com/LogEntry' name_descriptor: - pattern: "projects/{project}/logs/{log}" parent_type: "cloudresourcemanager.googleapis.com/Project" parent_name_extractor: "projects/{project}" - pattern: "folders/{folder}/logs/{log}" parent_type: "cloudresourcemanager.googleapis.com/Folder" parent_name_extractor: "folders/{folder}" - pattern: "organizations/{organization}/logs/{log}" parent_type: "cloudresourcemanager.googleapis.com/Organization" parent_name_extractor: "organizations/{organization}" - pattern: "billingAccounts/{billing_account}/logs/{log}" parent_type: "billing.googleapis.com/BillingAccount" parent_name_extractor: "billingAccounts/{billing_account}" For flexible resources, the resource name doesn't contain parent names, but the resource itself has parents for policy evaluation. Example: message Shelf { option (google.api.resource) = { type: "library.googleapis.com/Shelf" name_descriptor: { pattern: "shelves/{shelf}" parent_type: "cloudresourcemanager.googleapis.com/Project" } name_descriptor: { pattern: "shelves/{shelf}" parent_type: "cloudresourcemanager.googleapis.com/Folder" } }; } The ResourceDescriptor Yaml config will look like: resources: - type: 'library.googleapis.com/Shelf' name_descriptor: - pattern: "shelves/{shelf}" parent_type: "cloudresourcemanager.googleapis.com/Project" - pattern: "shelves/{shelf}" parent_type: "cloudresourcemanager.googleapis.com/Folder"

string type = 1
The resource type. It must be in the format of {service_name}/{resource_type_kind}. The `resource_type_kind` must be singular and must not include version numbers. Example: `storage.googleapis.com/Bucket` The value of the resource_type_kind must follow the regular expression /[A-Za-z][a-zA-Z0-9]+/. It should start with an upper case character and should use PascalCase (UpperCamelCase). The maximum number of characters allowed for the `resource_type_kind` is 100.
repeated string pattern = 2
Optional. The relative resource name pattern associated with this resource type. The DNS prefix of the full resource name shouldn't be specified here. The path pattern must follow the syntax, which aligns with HTTP binding syntax: Template = Segment { "/" Segment } ; Segment = LITERAL | Variable ; Variable = "{" LITERAL "}" ; Examples: - "projects/{project}/topics/{topic}" - "projects/{project}/knowledgeBases/{knowledge_base}" The components in braces correspond to the IDs for each resource in the hierarchy. It is expected that, if multiple patterns are provided, the same component name (e.g. "project") refers to IDs of the same type of resource.
string name_field = 3
Optional. The field on the resource that designates the resource name field. If omitted, this is assumed to be "name".
ResourceDescriptor.History history = 4
Optional. The historical or future-looking state of the resource pattern. Example: // The InspectTemplate message originally only supported resource // names with organization, and project was added later. message InspectTemplate { option (google.api.resource) = { type: "dlp.googleapis.com/InspectTemplate" pattern: "organizations/{organization}/inspectTemplates/{inspect_template}" pattern: "projects/{project}/inspectTemplates/{inspect_template}" history: ORIGINALLY_SINGLE_PATTERN }; }
string plural = 5
The plural name used in the resource name and permission names, such as 'projects' for the resource name of 'projects/{project}' and the permission name of 'cloudresourcemanager.googleapis.com/projects.get'. It is the same concept of the `plural` field in k8s CRD spec https://kubernetes.io/docs/tasks/access-kubernetes-api/custom-resources/custom-resource-definitions/ Note: The plural form is required even for singleton resources. See https://aip.dev/156
string singular = 6
The same concept of the `singular` field in k8s CRD spec https://kubernetes.io/docs/tasks/access-kubernetes-api/custom-resources/custom-resource-definitions/ Such as "project" for the `resourcemanager.googleapis.com/Project` type.
repeated ResourceDescriptor.Style style = 10
Style flag(s) for this resource. These indicate that a resource is expected to conform to a given style. See the specific style flags for additional information.

A description of the historical or future-looking state of the resource pattern.

Used in: ResourceDescriptor

HISTORY_UNSPECIFIED = 0
The "unset" value.
ORIGINALLY_SINGLE_PATTERN = 1
The resource originally had one pattern and launched as such, and additional patterns were added later.
FUTURE_MULTI_PATTERN = 2
The resource has one pattern, but the API owner expects to add more later. (This is the inverse of ORIGINALLY_SINGLE_PATTERN, and prevents that from being necessary once there are multiple patterns.)

A flag representing a specific style that a resource claims to conform to.

Used in: ResourceDescriptor

STYLE_UNSPECIFIED = 0
The unspecified value. Do not use.
DECLARATIVE_FRIENDLY = 1
This resource is intended to be "declarative-friendly". Declarative-friendly resources must be more strictly consistent, and setting this to true communicates to tools that this resource should adhere to declarative-friendly expectations. Note: This is used by the API linter (linter.aip.dev) to enable additional checks.

Defines a proto annotation that describes a string field that refers to an API resource.

string type = 1
The resource type that the annotated field references. Example: message Subscription { string topic = 2 [(google.api.resource_reference) = { type: "pubsub.googleapis.com/Topic" }]; } Occasionally, a field may reference an arbitrary resource. In this case, APIs use the special value * in their resource reference. Example: message GetIamPolicyRequest { string resource = 2 [(google.api.resource_reference) = { type: "*" }]; }
string child_type = 2
The resource type of a child collection that the annotated field references. This is useful for annotating the `parent` field that doesn't have a fixed resource type. Example: message ListLogEntriesRequest { string parent = 1 [(google.api.resource_reference) = { child_type: "logging.googleapis.com/LogEntry" }; }

A projection from an input message to the GRPC or REST header.

Used in: RoutingRule

string field = 1
A request field to extract the header key-value pair from.
string path_template = 2
A pattern matching the key-value field. Optional. If not specified, the whole field specified in the `field` field will be taken as value, and its name used as key. If specified, it MUST contain exactly one named segment (along with any number of unnamed segments) The pattern will be matched over the field specified in the `field` field, then if the match is successful: - the name of the single named segment will be used as a header name, - the match value of the segment will be used as a header value; if the match is NOT successful, nothing will be sent. Example: -- This is a field in the request message | that the header value will be extracted from. | | -- This is the key name in the | | routing header. V | field: "table_name" v path_template: "projects/*/{table_location=instances/*}/tables/*" ^ ^ | | In the {} brackets is the pattern that -- | specifies what to extract from the | field as a value to be sent. | | The string in the field must match the whole pattern -- before brackets, inside brackets, after brackets. When looking at this specific example, we can see that: - A key-value pair with the key `table_location` and the value matching `instances/*` should be added to the x-goog-request-params routing header. - The value is extracted from the request message's `table_name` field if it matches the full pattern specified: `projects/*/instances/*/tables/*`. **NB:** If the `path_template` field is not provided, the key name is equal to the field name, and the whole field should be sent as a value. This makes the pattern for the field and the value functionally equivalent to `**`, and the configuration { field: "table_name" } is a functionally equivalent shorthand to: { field: "table_name" path_template: "{table_name=**}" } See Example 1 for more details.

Specifies the routing information that should be sent along with the request in the form of routing header. **NOTE:** All service configuration rules follow the "last one wins" order. The examples below will apply to an RPC which has the following request type: Message Definition: message Request { // The name of the Table // Values can be of the following formats: // - `projects/<project>/tables/<table>` // - `projects/<project>/instances/<instance>/tables/<table>` // - `region/<region>/zones/<zone>/tables/<table>` string table_name = 1; // This value specifies routing for replication. // It can be in the following formats: // - `profiles/<profile_id>` // - a legacy `profile_id` that can be any string string app_profile_id = 2; } Example message: { table_name: projects/proj_foo/instances/instance_bar/table/table_baz, app_profile_id: profiles/prof_qux } The routing header consists of one or multiple key-value pairs. Every key and value must be percent-encoded, and joined together in the format of `key1=value1&key2=value2`. In the examples below I am skipping the percent-encoding for readablity. Example 1 Extracting a field from the request to put into the routing header unchanged, with the key equal to the field name. annotation: option (google.api.routing) = { // Take the `app_profile_id`. routing_parameters { field: "app_profile_id" } }; result: x-goog-request-params: app_profile_id=profiles/prof_qux Example 2 Extracting a field from the request to put into the routing header unchanged, with the key different from the field name. annotation: option (google.api.routing) = { // Take the `app_profile_id`, but name it `routing_id` in the header. routing_parameters { field: "app_profile_id" path_template: "{routing_id=**}" } }; result: x-goog-request-params: routing_id=profiles/prof_qux Example 3 Extracting a field from the request to put into the routing header, while matching a path template syntax on the field's value. NB: it is more useful to send nothing than to send garbage for the purpose of dynamic routing, since garbage pollutes cache. Thus the matching. Sub-example 3a The field matches the template. annotation: option (google.api.routing) = { // Take the `table_name`, if it's well-formed (with project-based // syntax). routing_parameters { field: "table_name" path_template: "{table_name=projects/*/instances/*/**}" } }; result: x-goog-request-params: table_name=projects/proj_foo/instances/instance_bar/table/table_baz Sub-example 3b The field does not match the template. annotation: option (google.api.routing) = { // Take the `table_name`, if it's well-formed (with region-based // syntax). routing_parameters { field: "table_name" path_template: "{table_name=regions/*/zones/*/**}" } }; result: <no routing header will be sent> Sub-example 3c Multiple alternative conflictingly named path templates are specified. The one that matches is used to construct the header. annotation: option (google.api.routing) = { // Take the `table_name`, if it's well-formed, whether // using the region- or projects-based syntax. routing_parameters { field: "table_name" path_template: "{table_name=regions/*/zones/*/**}" } routing_parameters { field: "table_name" path_template: "{table_name=projects/*/instances/*/**}" } }; result: x-goog-request-params: table_name=projects/proj_foo/instances/instance_bar/table/table_baz Example 4 Extracting a single routing header key-value pair by matching a template syntax on (a part of) a single request field. annotation: option (google.api.routing) = { // Take just the project id from the `table_name` field. routing_parameters { field: "table_name" path_template: "{routing_id=projects/*}/**" } }; result: x-goog-request-params: routing_id=projects/proj_foo Example 5 Extracting a single routing header key-value pair by matching several conflictingly named path templates on (parts of) a single request field. The last template to match "wins" the conflict. annotation: option (google.api.routing) = { // If the `table_name` does not have instances information, // take just the project id for routing. // Otherwise take project + instance. routing_parameters { field: "table_name" path_template: "{routing_id=projects/*}/**" } routing_parameters { field: "table_name" path_template: "{routing_id=projects/*/instances/*}/**" } }; result: x-goog-request-params: routing_id=projects/proj_foo/instances/instance_bar Example 6 Extracting multiple routing header key-value pairs by matching several non-conflicting path templates on (parts of) a single request field. Sub-example 6a Make the templates strict, so that if the `table_name` does not have an instance information, nothing is sent. annotation: option (google.api.routing) = { // The routing code needs two keys instead of one composite // but works only for the tables with the "project-instance" name // syntax. routing_parameters { field: "table_name" path_template: "{project_id=projects/*}/instances/*/**" } routing_parameters { field: "table_name" path_template: "projects/*/{instance_id=instances/*}/**" } }; result: x-goog-request-params: project_id=projects/proj_foo&instance_id=instances/instance_bar Sub-example 6b Make the templates loose, so that if the `table_name` does not have an instance information, just the project id part is sent. annotation: option (google.api.routing) = { // The routing code wants two keys instead of one composite // but will work with just the `project_id` for tables without // an instance in the `table_name`. routing_parameters { field: "table_name" path_template: "{project_id=projects/*}/**" } routing_parameters { field: "table_name" path_template: "projects/*/{instance_id=instances/*}/**" } }; result (is the same as 6a for our example message because it has the instance information): x-goog-request-params: project_id=projects/proj_foo&instance_id=instances/instance_bar Example 7 Extracting multiple routing header key-value pairs by matching several path templates on multiple request fields. NB: note that here there is no way to specify sending nothing if one of the fields does not match its template. E.g. if the `table_name` is in the wrong format, the `project_id` will not be sent, but the `routing_id` will be. The backend routing code has to be aware of that and be prepared to not receive a full complement of keys if it expects multiple. annotation: option (google.api.routing) = { // The routing needs both `project_id` and `routing_id` // (from the `app_profile_id` field) for routing. routing_parameters { field: "table_name" path_template: "{project_id=projects/*}/**" } routing_parameters { field: "app_profile_id" path_template: "{routing_id=**}" } }; result: x-goog-request-params: project_id=projects/proj_foo&routing_id=profiles/prof_qux Example 8 Extracting a single routing header key-value pair by matching several conflictingly named path templates on several request fields. The last template to match "wins" the conflict. annotation: option (google.api.routing) = { // The `routing_id` can be a project id or a region id depending on // the table name format, but only if the `app_profile_id` is not set. // If `app_profile_id` is set it should be used instead. routing_parameters { field: "table_name" path_template: "{routing_id=projects/*}/**" } routing_parameters { field: "table_name" path_template: "{routing_id=regions/*}/**" } routing_parameters { field: "app_profile_id" path_template: "{routing_id=**}" } }; result: x-goog-request-params: routing_id=profiles/prof_qux Example 9 Bringing it all together. annotation: option (google.api.routing) = { // For routing both `table_location` and a `routing_id` are needed. // // table_location can be either an instance id or a region+zone id. // // For `routing_id`, take the value of `app_profile_id` // - If it's in the format `profiles/<profile_id>`, send // just the `<profile_id>` part. // - If it's any other literal, send it as is. // If the `app_profile_id` is empty, and the `table_name` starts with // the project_id, send that instead. routing_parameters { field: "table_name" path_template: "projects/*/{table_location=instances/*}/tables/*" } routing_parameters { field: "table_name" path_template: "{table_location=regions/*/zones/*}/tables/*" } routing_parameters { field: "table_name" path_template: "{routing_id=projects/*}/**" } routing_parameters { field: "app_profile_id" path_template: "{routing_id=**}" } routing_parameters { field: "app_profile_id" path_template: "profiles/{routing_id=*}" } }; result: x-goog-request-params: table_location=instances/instance_bar&routing_id=prof_qux

repeated RoutingParameter routing_parameters = 2
A collection of Routing Parameter specifications. **NOTE:** If multiple Routing Parameters describe the same key (via the `path_template` field or via the `field` field when `path_template` is not provided), "last one wins" rule determines which Parameter gets used. See the examples for more details.

`Service` is the root object of Google service configuration schema. It describes basic information about a service, such as the name and the title, and delegates other aspects to sub-sections. Each sub-section is either a proto message or a repeated proto message that configures a specific aspect, such as auth. See each proto message definition for details. Example: type: google.api.Service config_version: 3 name: calendar.googleapis.com title: Google Calendar API apis: - name: google.calendar.v3.Calendar authentication: providers: - id: google_calendar_auth jwks_uri: https://www.googleapis.com/oauth2/v1/certs issuer: https://securetoken.google.com rules: - selector: "*" requirements: provider_id: google_calendar_auth

optional protobuf.UInt32Value config_version = 20
The semantic version of the service configuration. The config version affects the interpretation of the service configuration. For example, certain features are enabled by default for certain config versions. The latest config version is `3`.
string name = 1
The DNS address at which this service is available, e.g. `calendar.googleapis.com`.
string id = 33
A unique ID for a specific instance of this message, typically assigned by the client for tracking purpose. If empty, the server may choose to generate one instead.
string title = 2
The product title for this service.
string producer_project_id = 22
The Google project that owns this service.
repeated protobuf.Api apis = 3
A list of API interfaces exported by this service. Only the `name` field of the [google.protobuf.Api][google.protobuf.Api] needs to be provided by the configuration author, as the remaining fields will be derived from the IDL during the normalization process. It is an error to specify an API interface here which cannot be resolved against the associated IDL files.
repeated protobuf.Type types = 4
A list of all proto message types included in this API service. Types referenced directly or indirectly by the `apis` are automatically included. Messages which are not referenced but shall be included, such as types used by the `google.protobuf.Any` type, should be listed here by name. Example: types: - name: google.protobuf.Int32
repeated protobuf.Enum enums = 5
A list of all enum types included in this API service. Enums referenced directly or indirectly by the `apis` are automatically included. Enums which are not referenced but shall be included should be listed here by name. Example: enums: - name: google.someapi.v1.SomeEnum

repeated LogDescriptor logs = 23
Defines the logs used by this service.
repeated MetricDescriptor metrics = 24
Defines the metrics used by this service.

Source information used to create a Service Config

Used in: Service

repeated protobuf.Any source_files = 1
All files used during config generation.

Define a parameter's name and location. The parameter may be passed as either an HTTP header or a URL query parameter, and if both are passed the behavior is implementation-dependent.

Used in: SystemParameterRule

string name = 1
Define the name of the parameter, such as "api_key" . It is case sensitive.
string http_header = 2
Define the HTTP header name to use for the parameter. It is case insensitive.
string url_query_parameter = 3
Define the URL query parameter name to use for the parameter. It is case sensitive.

Define a system parameter rule mapping system parameter definitions to methods.

Used in: SystemParameters

string selector = 1
Selects the methods to which this rule applies. Use '*' to indicate all methods in all APIs. Refer to [selector][google.api.DocumentationRule.selector] for syntax details.
repeated SystemParameter parameters = 2
Define parameters. Multiple names may be defined for a parameter. For a given method call, only one of them should be used. If multiple names are used the behavior is implementation-dependent. If none of the specified names are present the behavior is parameter-dependent.

### System parameter configuration A system parameter is a special kind of parameter defined by the API system, not by an individual API. It is typically mapped to an HTTP header and/or a URL query parameter. This configuration specifies which methods change the names of the system parameters.

Used in: Service

repeated SystemParameterRule rules = 1
Define system parameters. The parameters defined here will override the default parameters implemented by the system. If this field is missing from the service config, default system parameters will be used. Default system parameters and names is implementation-dependent. Example: define api key for all methods system_parameters rules: - selector: "*" parameters: - name: api_key url_query_parameter: api_key Example: define 2 api key names for a specific method. system_parameters rules: - selector: "/ListShelves" parameters: - name: api_key http_header: Api-Key1 - name: api_key http_header: Api-Key2 **NOTE:** All service configuration rules follow "last one wins" order.

Configuration controlling usage of a service.

Used in: Service

repeated string requirements = 1
Requirements that must be satisfied before a consumer project can use the service. Each requirement is of the form <service.name>/<requirement-id>; for example 'serviceusage.googleapis.com/billing-enabled'.
repeated UsageRule rules = 6
A list of usage rules that apply to individual API methods. **NOTE:** All service configuration rules follow "last one wins" order.
string producer_notification_channel = 7
The full resource name of a channel used for sending notifications to the service producer. Google Service Management currently only supports [Google Cloud Pub/Sub](https://cloud.google.com/pubsub) as a notification channel. To use Google Cloud Pub/Sub as the channel, this must be the name of a Cloud Pub/Sub topic that uses the Cloud Pub/Sub topic name format documented in https://cloud.google.com/pubsub/docs/overview.

Usage configuration rules for the service. NOTE: Under development. Use this rule to configure unregistered calls for the service. Unregistered calls are calls that do not contain consumer project identity. (Example: calls that do not contain an API key). By default, API methods do not allow unregistered calls, and each method call must be identified by a consumer project identity. Use this rule to allow/disallow unregistered calls. Example of an API that wants to allow unregistered calls for entire service. usage: rules: - selector: "*" allow_unregistered_calls: true Example of a method that wants to allow unregistered calls. usage: rules: - selector: "google.example.library.v1.LibraryService.CreateBook" allow_unregistered_calls: true

Used in: Usage

string selector = 1
Selects the methods to which this rule applies. Use '*' to indicate all methods in all APIs. Refer to [selector][google.api.DocumentationRule.selector] for syntax details.
bool allow_unregistered_calls = 2
If true, the selected method allows unregistered calls, e.g. calls that don't identify any user or application.
bool skip_service_control = 3
If true, the selected method should skip service control and the control plane features, such as quota and billing, will not be available. This flag is used by Google Cloud Endpoints to bypass checks for internal methods, such as service health check methods.
