• uint64 timestamp_epoch_millis = 1

  * The UNIX timestamp (in milliseconds) when this attempt was created.

• string sender_name = 2

  * The name of the `VerificationCodeSender` used in this attempt.

• rpc.MessageTransport message_transport = 3

  * The message transport used in the failed attempt

• rpc.ClientType client_type = 4

  * The type of client that initiated this attempt.

• FailedSendReason failed_send_reason = 5

• string selection_reason = 6

  * Indicates the reason we selected particular sender. (e.g. 'adaptive', 'configured', 'lang_support', 'random')

Used in: FailedSendAttempt

• FAILED_SEND_REASON_UNSPECIFIED = 0

• FAILED_SEND_REASON_SUSPECTED_FRAUD = 1

  * The attempt was not sent due to suspected fraud

• FAILED_SEND_REASON_REJECTED = 2

  * The attempt was refused by the sender

• FAILED_SEND_REASON_UNAVAILABLE = 3

  * The attempt failed because the sender could not be reached or had an unexpected error

Used in: RegistrationSession

• uint64 timestamp_epoch_millis = 1

  * The UNIX timestamp (in milliseconds) when this attempt was created.

• string sender_name = 2

  * The name of the `VerificationCodeSender` used in this attempt.

• rpc.MessageTransport message_transport = 3

• bytes sender_data = 4

  * An opaque collection of bytes provided by senders when an attempt is created and presented to senders when a caller checks a verification code. Verification code senders can use this space to store whatever state they may need to check a verification code (the code itself, for example, or an upstream session ID) after an attempt has been created.

• uint64 expiration_epoch_millis = 5

  * The UNIX timestamp (in milliseconds) at which this attempt will no longer be valid.

• string remote_id = 6

  * A sender-specific identifier for this attempt. This may be an upstream session identifier, for example. The interpretation of this value will vary by sender. Senders that do not have remote session identifiers may leave this field blank. Remote session identifiers are not guaranteed to be unique.

• rpc.ClientType client_type = 7

  * The type of client that initiated this attempt.

• string selection_reason = 8

  * Indicates the reason we selected particular sender. (e.g. 'adaptive', 'configured', 'lang_support', 'random')

* A registration session stores information about a current attempt to register a phone number. Registration sessions are created when a client first requests that a verification code be sent to a phone number and store all state related to the registration attempt including the phone number being registered, the VerificationCodeSender responsible for sending and verifying registration codes, and any persistent data that sender may need to verify codes.

• string phone_number = 1

  * The E.164-formatted representation of the phone number being registered in this session.

• string verified_code = 4

  * The successfully-verified code associated with this session. If this field is not blank, the remote client has successfully verified their registration. Callers may use this value to de-duplicate verification attempts (i.e. repeated submissions from a remote client due to an interrupted connection).

• repeated RegistrationAttempt registration_attempts = 5

• bytes id = 6

  * A unique identifier for this session.

• uint32 check_code_attempts = 7

  * The number of times a caller has attempted to check a verification code for the active registration attempt.

• uint64 last_check_code_attempt_epoch_millis = 8

  * The UNIX timestamp (in milliseconds) at which a caller last attempted to check a verification code for the active registration attempt.

• uint64 expiration_epoch_millis = 9

  * The UNIX timestamp (in milliseconds) after which this session will expire.

• uint64 created_epoch_millis = 10

  * The UNIX timestamp (in milliseconds) at which this session was created.

• optional SessionMetadata session_metadata = 11

• repeated rpc.MessageTransport rejected_transports = 12

  * A list of transports that have been rejected by senders when attempting to send verification codes in the scope of this session.

• repeated FailedSendAttempt failed_attempts = 13

  * A list of attempts that failed to send

Used in: RegistrationSession

• bool account_exists_with_e164 = 1

  * Indicates whether an account already exists with the given e164 (i.e. this session represents a "re-registration" attempt).

• string mcc = 2

  * The MCC as reported by a number lookup service.

• string mnc = 3

  * The MNC as reported by a number lookup service.
