service Lightning
lightning.proto:26Lightning is the main RPC server of the daemon.
rpc AbandonChannel (, )
lightning.proto:263lncli: `abandonchannel` AbandonChannel removes all channel state from the database except for a close summary. This method can be used to get rid of permanently unusable channels due to bugs fixed in newer versions of lnd. This method can also be used to remove externally funded channels where the funding transaction was never broadcast. Only available for non-externally funded channels in dev build.
message
lightning.proto:4494optional channel_point = 1
bool pending_funding_shim_only = 2
bool i_know_what_i_am_doing = 3
Override the requirement for being in dev mode by setting this to true and confirming the user knows what they are doing and this is a potential foot gun to lose funds if used on active channels.
message
lightning.proto:4507string status = 1
The status of the abandon operation.
rpc AddInvoice (, )
lightning.proto:270lncli: `addinvoice` AddInvoice attempts to add a new invoice to the invoice database. Any duplicated invoices are rejected, therefore all invoices *must* have a unique payment preimage.
message
lightning.proto:4120bytes r_hash = 1

bytes payment_addr = 17
The payment address of the generated invoice. This is also called payment secret in specifications (e.g. BOLT 11). This value should be used in all payments for this invoice as we require it for end to end security.
rpc BakeMacaroon (, )
lightning.proto:494lncli: `bakemacaroon` BakeMacaroon allows the creation of a new macaroon with custom read and write permissions. No first-party caveats are added since this can be done offline.

lightning.proto:4905string macaroon = 1
The hex encoded macaroon, serialized in binary format.
rpc BatchOpenChannel (, )
lightning.proto:219lncli: `batchopenchannel` BatchOpenChannel attempts to open multiple single-funded channels in a single transaction in an atomic way. This means either all channel open requests succeed at once or all attempts are aborted if any of them fail. This is the safer variant of using PSBTs to manually fund a batch of channels through the OpenChannel RPC.
message
lightning.proto:2162repeated channels = 1
The list of channels to open.
int32 target_conf = 2
The target number of blocks that the funding transaction should be confirmed by.

rpc ChannelAcceptor (stream , stream )
lightning.proto:241ChannelAcceptor dispatches a bi-directional streaming RPC in which OpenChannel requests are sent to the client and the client responds with a boolean that tells LND whether or not to accept the channel. This allows node operators to specify their own criteria for accepting inbound channels through a single persistent connection.
message
lightning.proto:918bool accept = 1
Whether or not the client accepts the channel.
bytes pending_chan_id = 2
The pending channel id to which this response applies.
string error = 3
An optional error to send the initiating party to indicate why the channel was rejected. This field *should not* contain sensitive information, it will be sent to the initiating party. This field should only be set if accept is false, the channel will be rejected if an error is set with accept=true because the meaning of this response is ambiguous. Limited to 500 characters.
string upfront_shutdown = 4

uint32 csv_delay = 5
The csv delay (in blocks) that we require for the remote party.
uint64 reserve_sat = 6
The reserve amount in satoshis that we require the remote peer to adhere to. We require that the remote peer always have some reserve amount allocated to them so that there is always a disincentive to broadcast old state (if they hold 0 sats on their side of the channel, there is nothing to lose).

CheckMacaroonPermissions checks whether the provided macaroon contains all the provided permissions. If the macaroon is valid (e.g. all caveats are satisfied), and all permissions provided in the request are met, then this RPC returns true.
message
lightning.proto:5117bytes macaroon = 1
The macaroon to check permissions for, serialized in binary format. For a macaroon to be valid, it must have been issued by lnd, must succeed all caveat conditions, and must contain all of the permissions specified in the permissions field.
repeated permissions = 2
The list of permissions the macaroon should be checked against. Only if the macaroon contains all of these permissions, it is considered valid. If the list of permissions given is empty, then the macaroon is considered valid only based on issuance authority and caveat validity. An empty list of permissions is therefore equivalent to saying "skip checking permissions" (unless check_default_perms_from_full_method is specified).
string fullMethod = 3
The RPC method to check the macaroon against. This is only used if there are custom `uri:<rpcpackage>.<ServiceName>/<MethodName>` permissions in the permission list above. To check a macaroon against the list of permissions of a certain RPC method, query the `ListPermissions` RPC first, extract the permissions for the method, and then pass them in the `permissions` field above.
bool check_default_perms_from_full_method = 4
If this field is set to true, then the permissions list above MUST be empty. The default permissions for the provided fullMethod will be used to check the macaroon. This is equivalent to looking up the permissions for a method in the `ListPermissions` RPC and then calling this RPC with the permission list returned from that call. Without this flag, the list of permissions must be non-empty for the check to actually perform a permission check.
message
lightning.proto:5151bool valid = 1
rpc CloseChannel (, stream )
lightning.proto:253lncli: `closechannel` CloseChannel attempts to close an active channel identified by its channel outpoint (ChannelPoint). The actions of this method can additionally be augmented to attempt a force close after a timeout period in the case of an inactive peer. If a non-force close (cooperative closure) is requested, then the user can specify either a target number of blocks until the closure transaction is confirmed, or a manual fee rate. If neither are specified, then a default lax, block confirmation target is used.
message
lightning.proto:2070optional channel_point = 1
The outpoint (txid:index) of the funding transaction. With this value, Bob will be able to generate a signature for Alice's version of the commitment transaction.
bool force = 2
If true, then the channel will be closed forcibly. This means the current commitment transaction will be signed and broadcast.
int32 target_conf = 3
The target number of blocks that the closure transaction should be confirmed by.
int64 sat_per_byte = 4
Deprecated, use sat_per_vbyte. A manual fee rate set in sat/vbyte that should be used when crafting the closure transaction.
string delivery_address = 5
An optional address to send funds to in the case of a cooperative close. If the channel was opened with an upfront shutdown script and this field is set, the request to close will fail because the channel must pay out to the upfront shutdown addresss.
uint64 sat_per_vbyte = 6
A manual fee rate set in sat/vbyte that should be used when crafting the closure transaction.
uint64 max_fee_per_vbyte = 7
The maximum fee rate the closer is willing to pay. NOTE: This field is only respected if we're the initiator of the channel.
bool no_wait = 8
If true, then the rpc call will not block while it awaits a closing txid to be broadcasted to the mempool. To obtain the closing tx one has to listen to the stream for the particular updates. Moreover if a coop close is specified and this flag is set to true the coop closing flow will be initiated even if HTLCs are active on the channel. The channel will wait until all HTLCs are resolved and then start the coop closing process. The channel will be disabled in the meantime and will disallow any new HTLCs.

rpc DescribeGraph (, )
lightning.proto:343lncli: `describegraph` DescribeGraph returns a description of the latest graph state from the point of view of the node. The graph information is partitioned into two components: all the nodes/vertexes, and all the edges that connect the vertexes themselves. As this is a directed graph, the edges also contain the node directional specific routing policy which includes: the time lock delta, fee information, etc.
message
lightning.proto:3546bool include_unannounced = 1
Whether unannounced channels are included in the response or not. If set, unannounced channels are included. Unannounced channels are both private channels, and public channels that are not yet announced to the network.

rpc EstimateFee (, )
lightning.proto:56lncli: `estimatefee` EstimateFee asks the chain backend to estimate the fee rate and total fees for a transaction that pays to multiple specified outputs. When using REST, the `AddrToAmount` map type can be set by appending `&AddrToAmount[<address>]=<amount_to_send>` to the URL. Unfortunately this map type doesn't appear in the REST API documentation because of a bug in the grpc-gateway library.

Additionally, a multi-channel backup is returned as well, which contains a single encrypted blob containing the backups of each channel.
message
lightning.proto:4836(message has no fields)
lncli: `exportchanbackup` ExportChannelBackup attempts to return an encrypted static channel backup for the target channel identified by it channel point. The backup is encrypted with a key generated from the aezeed seed of the user. The returned backup can either be restored using the RestoreChannelBackup method once lnd is running, or via the InitWallet and UnlockWallet methods from the WalletUnlocker service.
message

rpc ForwardingHistory (, )
lightning.proto:436lncli: `fwdinghistory` ForwardingHistory allows the caller to query the htlcswitch for a record of all HTLCs forwarded within the target time range, and integer offset within that time range, for a maximum number of events. If no maximum number of events is specified, up to 100 events will be returned. If no time-range is specified, then events will be returned in the order that they occured. A list of forwarding events are returned. The size of each forwarding event is 40 bytes, and the max message size able to be returned in gRPC is 4 MiB. As a result each message can only contain 50k entries. Each response has the index offset of the last entry. The index offset can be provided to the request to allow the caller to skip a series of records.

rpc FundingStateStep (, )
lightning.proto:232FundingStateStep is an advanced funding related call that allows the caller to either execute some preparatory steps for a funding workflow, or manually progress a funding workflow. The primary way a funding flow is identified is via its pending channel ID. As an example, this method can be used to specify that we're expecting a funding flow for a particular pending channel ID, for which we need to use specific parameters. Alternatively, this can be used to interactively drive PSBT signing for funding for partially complete funding transactions.
message
lightning.proto:2653oneof trigger

lightning.proto:210lncli: `openchannel` OpenChannel attempts to open a singly funded channel specified in the request to a remote peer. Users are able to specify a target number of blocks that the funding transaction should be confirmed in, or a manual fee rate to us for the funding transaction. If neither are specified, then a lax block confirmation target is used. Each OpenStatusUpdate will return the pending channel ID of the in-progress channel. Depending on the arguments specified in the OpenChannelRequest, this pending channel ID can then be used to manually progress the channel funding flow.

The returned route contains the full details required to craft and send an HTLC, also including the necessary information that should be present within the Sphinx packet encapsulated within the HTLC. When using REST, the `dest_custom_records` map type can be set by appending `&dest_custom_records[<record_number>]=<record_data_base64_url_encoded>` to the URL. Unfortunately this map type doesn't appear in the REST API documentation because of a bug in the grpc-gateway library.

The amount to send expressed in millisatoshis. The fields amt and amt_msat are mutually exclusive.
int32 final_cltv_delta = 4
An optional CLTV delta from the current height that should be used for the timelock of the final hop. Note that unlike SendPayment, QueryRoutes does not add any additional block padding on top of final_ctlv_delta. This padding of a few blocks needs to be added manually or otherwise failures may happen when a block comes in while the payment is in flight. Note: must not be set if making a payment to a blinded path (delta is set by the aggregate parameters provided by blinded_payment_paths)
optional fee_limit = 5
The maximum number of satoshis that will be paid as a fee of the payment. This value can be represented either as a percentage of the amount being sent, or as a fixed amount of the maximum fee the user is willing the pay to send the payment.

uint32 cltv_limit = 11
An optional maximum total time lock for the route. If the source is empty or ourselves, this should not exceed lnd's `--max-cltv-expiry` setting. If zero, then the value of `--max-cltv-expiry` is used as the limit.
map<uint64, bytes> dest_custom_records = 13
An optional field that can be used to pass an arbitrary set of TLV records to a peer which understands the new records. This can be used to pass application specific data during the payment attempt. If the destination does not support the specified records, an error will be returned. Record types are required to be in the custom range >= 65536. When using REST, the values must be encoded as base64.

Optional route hints to reach the destination through private channels.
repeated blinded_payment_paths = 19
An optional blinded path(s) to reach the destination. Note that the introduction node must be provided as the first hop in the route.
repeated FeatureBit dest_features = 17
Features assumed to be supported by the final node. All transitive feature dependencies must also be set properly. For a given feature bit pair, either optional or remote may be set, but not both. If this field is nil or empty, the router will try to load destination features from the graph as a fallback. Note: must not be set if making a payment to a blinded route (features are provided in blinded_payment_paths).

rpc RegisterRPCMiddleware (stream , stream )
lightning.proto:539RegisterRPCMiddleware adds a new gRPC middleware to the interceptor chain. A gRPC middleware is software component external to lnd that aims to add additional business logic to lnd by observing/intercepting/validating incoming gRPC client requests and (if needed) replacing/overwriting outgoing messages before they're sent to the client. When registering the middleware must identify itself and indicate what custom macaroon caveats it wants to be responsible for. Only requests that contain a macaroon with that specific custom caveat are then sent to the middleware for inspection. The other option is to register for the read-only mode in which all requests/responses are forwarded for interception to the middleware but the middleware is not allowed to modify any responses. As a security measure, _no_ middleware can modify responses for requests made with _unencumbered_ macaroons!
message
lightning.proto:5294uint64 ref_msg_id = 1
The request message ID this response refers to. Must always be set when giving feedback to an intercept but is ignored for the initial registration message.
oneof middleware_message
The middleware can only send two types of messages to lnd: The initial registration message that identifies the middleware and after that only feedback messages to requests sent to the middleware.
register = 2
The registration message identifies the middleware that's being registered in lnd. The registration message must be sent immediately after initiating the RegisterRpcMiddleware stream, otherwise lnd will time out the attempt and terminate the request. NOTE: The middleware will only receive interception messages for requests that contain a macaroon with the custom caveat that the middleware declares it is responsible for handling in the registration message! As a security measure, _no_ middleware can intercept requests made with _unencumbered_ macaroons!
feedback = 3
The middleware received an interception request and gives feedback to it. The request_id indicates what message the feedback refers to.
message
lightning.proto:5155uint64 request_id = 1
The unique ID of the intercepted original gRPC request. Useful for mapping request to response when implementing full duplex message interception. For streaming requests, this will be the same ID for all incoming and outgoing middleware intercept messages of the _same_ stream.
bytes raw_macaroon = 2
The raw bytes of the complete macaroon as sent by the gRPC client in the original request. This might be empty for a request that doesn't require macaroons such as the wallet unlocker RPCs.
string custom_caveat_condition = 3
The parsed condition of the macaroon's custom caveat for convenient access. This field only contains the value of the custom caveat that the handling middleware has registered itself for. The condition _must_ be validated for messages of intercept_type stream_auth and request!
oneof intercept_type
There are three types of messages that will be sent to the middleware for inspection and approval: Stream authentication, request and response interception. The first two can only be accepted (=forward to main RPC server) or denied (=return error to client). Intercepted responses can also be replaced/overwritten.
stream_auth = 4
Intercept stream authentication: each new streaming RPC call that is initiated against lnd and contains the middleware's custom macaroon caveat can be approved or denied based upon the macaroon in the stream header. This message will only be sent for streaming RPCs, unary RPCs must handle the macaroon authentication in the request interception to avoid an additional message round trip between lnd and the middleware.
request = 5
Intercept incoming gRPC client request message: all incoming messages, both on streaming and unary RPCs, are forwarded to the middleware for inspection. For unary RPC messages the middleware is also expected to validate the custom macaroon caveat of the request.
response = 6
Intercept outgoing gRPC response message: all outgoing messages, both on streaming and unary RPCs, are forwarded to the middleware for inspection and amendment. The response in this message is the original response as it was generated by the main RPC server. It can either be accepted (=forwarded to the client), replaced/overwritten with a new message of the same type, or replaced by an error message.
bool reg_complete = 8
This is used to indicate to the client that the server has successfully registered the interceptor. This is only used in the very first message that the server sends to the client after the client sends the server the middleware registration message.
uint64 msg_id = 7
The unique message ID of this middleware intercept message. There can be multiple middleware intercept messages per single gRPC request (one for the incoming request and one for the outgoing response) or gRPC stream (one for each incoming message and one for each outgoing response). This message ID must be referenced when responding (accepting/rejecting/modifying) to an intercept message.
map<string, > metadata_pairs = 9
The metadata pairs that were sent along with the original gRPC request via the golang context.Context using explicit [gRPC metadata](https://grpc.io/docs/guides/metadata/). Context values are not propagated via gRPC and so we send any pairs along explicitly here so that the interceptor can access them.
lncli: `restorechanbackup` RestoreChannelBackups accepts a set of singular channel backups, or a single encrypted multi-chan backup and attempts to recover any funds remaining within the channel.

bool stateless_init = 3
stateless_init is an optional argument instructing the daemon NOT to create any *.macaroon files in its filesystem. If this parameter is set, then the admin macaroon returned in the response MUST be stored by the caller of the RPC as otherwise all access to the daemon will be lost!
bool new_macaroon_root_key = 4
new_macaroon_root_key is an optional argument instructing the daemon to rotate the macaroon root key when set to true. This will invalidate all previously generated macaroons.
message
walletunlocker.proto:328bytes admin_macaroon = 1
The binary serialized admin macaroon that can be used to access the daemon after rotating the macaroon root key. If both the stateless_init and new_macaroon_root_key parameter were set to true, this is the ONLY copy of the macaroon that was created from the new root key and MUST be stored safely by the caller. Otherwise a copy of this macaroon is also persisted on disk by the daemon, together with other macaroon files.
rpc GenSeed (, )
walletunlocker.proto:40GenSeed is the first method that should be used to instantiate a new lnd instance. This method allows a caller to generate a new aezeed cipher seed given an optional passphrase. If provided, the passphrase will be necessary to decrypt the cipherseed to expose the internal wallet seed. Once the cipherseed is obtained and verified by the user, the InitWallet method should be used to commit the newly generated seed, and create the wallet.
message
walletunlocker.proto:71bytes aezeed_passphrase = 1
aezeed_passphrase is an optional user provided passphrase that will be used to encrypt the generated aezeed cipher seed. When using REST, this field must be encoded as base64.
bytes seed_entropy = 2
seed_entropy is an optional 16-bytes generated via CSPRNG. If not specified, then a fresh set of randomness will be used to create the seed. When using REST, this field must be encoded as base64.
message
walletunlocker.proto:86repeated string cipher_seed_mnemonic = 1
cipher_seed_mnemonic is a 24-word mnemonic that encodes a prior aezeed cipher seed obtained by the user. This field is optional, as if not provided, then the daemon will generate a new cipher seed for the user. Otherwise, then the daemon will attempt to recover the wallet state linked to this cipher seed.
bytes enciphered_seed = 2
enciphered_seed are the raw aezeed cipher seed bytes. This is the raw cipher text before run through our mnemonic encoding scheme.
rpc InitWallet (, )
walletunlocker.proto:56InitWallet is used when lnd is starting up for the first time to fully initialize the daemon and its internal wallet. At the very least a wallet password must be provided. This will be used to encrypt sensitive material on disk. In the case of a recovery scenario, the user can also specify their aezeed mnemonic and passphrase. If set, then the daemon will use this prior state to initialize its internal wallet. Alternatively, this can be used along with the GenSeed RPC to obtain a seed, then present it to the user. Once it has been verified by the user, the seed can be fed into this RPC in order to commit the new wallet.
message
walletunlocker.proto:103bytes wallet_password = 1
wallet_password is the passphrase that should be used to encrypt the wallet. This MUST be at least 8 chars in length. After creation, this password is required to unlock the daemon. When using REST, this field must be encoded as base64.
repeated string cipher_seed_mnemonic = 2
cipher_seed_mnemonic is a 24-word mnemonic that encodes a prior aezeed cipher seed obtained by the user. This may have been generated by the GenSeed method, or be an existing seed.
bytes aezeed_passphrase = 3
aezeed_passphrase is an optional user provided passphrase that will be used to encrypt the generated aezeed cipher seed. When using REST, this field must be encoded as base64.
int32 recovery_window = 4
recovery_window is an optional argument specifying the address lookahead when restoring a wallet seed. The recovery window applies to each individual branch of the BIP44 derivation paths. Supplying a recovery window of zero indicates that no addresses should be recovered, such after the first initialization of the wallet.
optional channel_backups = 5
channel_backups is an optional argument that allows clients to recover the settled funds within a set of channels. This should be populated if the user was unable to close out all channels and sweep funds before partial or total data loss occurred. If specified, then after on-chain recovery of funds, lnd begin to carry out the data loss recovery protocol in order to recover the funds in each channel from a remote force closed transaction.
bool stateless_init = 6
stateless_init is an optional argument instructing the daemon NOT to create any *.macaroon files in its filesystem. If this parameter is set, then the admin macaroon returned in the response MUST be stored by the caller of the RPC as otherwise all access to the daemon will be lost!
string extended_master_key = 7
extended_master_key is an alternative to specifying cipher_seed_mnemonic and aezeed_passphrase. Instead of deriving the master root key from the entropy of an aezeed cipher seed, the given extended master root key is used directly as the wallet's master key. This allows users to import/use a master key from another wallet. When doing so, lnd still uses its default SegWit only (BIP49/84) derivation paths and funds from custom/non-default derivation paths will not automatically appear in the on-chain wallet. Using an 'xprv' instead of an aezeed also has the disadvantage that the wallet's birthday is not known as that is an information that's only encoded in the aezeed, not the xprv. Therefore a birthday needs to be specified in extended_master_key_birthday_timestamp or a "safe" default value will be used.
uint64 extended_master_key_birthday_timestamp = 8
extended_master_key_birthday_timestamp is the optional unix timestamp in seconds to use as the wallet's birthday when using an extended master key to restore the wallet. lnd will only start scanning for funds in blocks that are after the birthday which can speed up the process significantly. If the birthday is not known, this should be left at its default value of 0 in which case lnd will start scanning from the first SegWit block (481824 on mainnet).
optional watch_only = 9
watch_only is the third option of initializing a wallet: by importing account xpubs only and therefore creating a watch-only wallet that does not contain any private keys. That means the wallet won't be able to sign for any of the keys and _needs_ to be run with a remote signer that has the corresponding private keys and can serve signing RPC requests.
bytes macaroon_root_key = 10
macaroon_root_key is an optional 32 byte macaroon root key that can be provided when initializing the wallet rather than letting lnd generate one on its own.
message
walletunlocker.proto:196bytes admin_macaroon = 1
The binary serialized admin macaroon that can be used to access the daemon after creating the wallet. If the stateless_init parameter was set to true, this is the ONLY copy of the macaroon and MUST be stored safely by the caller. Otherwise a copy of this macaroon is also persisted on disk by the daemon, together with other macaroon files.
rpc UnlockWallet (, )

message
walletunlocker.proto:264bytes wallet_password = 1

int32 recovery_window = 2
recovery_window is an optional argument specifying the address lookahead when restoring a wallet seed. The recovery window applies to each individual branch of the BIP44 derivation paths. Supplying a recovery window of zero indicates that no addresses should be recovered, such after the first initialization of the wallet.
optional channel_backups = 3
channel_backups is an optional argument that allows clients to recover the settled funds within a set of channels.

int32 funding_expiry_blocks = 3
The number of blocks until the funding transaction is considered expired. If this value gets close to zero, there is a risk that the channel funding will be canceled by the channel responder. The channel should be fee bumped using CPFP (see walletrpc.BumpFee) to ensure that the channel confirms in time. Otherwise a force-close will be necessary if the channel confirms after the funding transaction expires. A negative value means the channel responder has very likely canceled the funding and the channel will never become fully operational.
uint32 confirmations_until_active = 7

"Active" here means both channel peers have the channel marked OPEN and can immediately start using it. For public channels, this does not imply a channel_announcement has been gossiped. It only becomes public on the network after 6 on‐chain confirmations. See BOLT07 "Routing Gossip": https://github.com/lightning/bolts/blob/master/07-routing-gossip.md ZeroConf channels bypass the pending state entirely: they are marked active immediately upon creation, so they never show up as "pending".

An optional base PSBT the new channel output will be added to. If this is non-empty, it must be a binary serialized PSBT.
bool no_publish = 3
If a channel should be part of a batch (multiple channel openings in one transaction), it can be dangerous if the whole batch transaction is published too early before all channel opening negotiations are completed. This flag prevents this particular channel from broadcasting the transaction after the negotiation with the remote peer. In a batch of channel openings this flag should be set to true for every channel but the very last.

ResolverOutcomeAbandoned indicates that an output that we did not claim on chain, for example an anchor that we did not sweep and a third party claimed on chain, or a htlc that we could not decode so left unclaimed.
FIRST_STAGE = 4
If we force closed our channel, our htlcs need to be claimed in two stages. This outcome represents the broadcast of a timeout or success transaction for this two stage htlc claim.

ANCHOR = 1
We resolved an anchor output.
INCOMING_HTLC = 2
We are resolving an incoming htlc on chain. This if this htlc is claimed, we swept the incoming htlc with the preimage. If it is timed out, our peer swept the timeout path.

lightning.proto:3358A path through the channel graph which runs over one or more channels in succession. This struct carries all the information required to craft the Sphinx onion packet, and send the payment along the first hop in the path. A route is only selected as valid if all the channels have sufficient capacity to carry the initial payment amount after fees are accounted for.

uint32 total_time_lock = 1
The cumulative (final) time lock across the entire route. This is the CLTV value that should be extended to the first hop in the route. All other hops will decrement the time-lock as advertised, leaving enough time for all hops to wait for or present the payment preimage to complete the payment.
int64 total_fees = 2
The sum of the fees paid at each hop within the final route. In the case of a one-hop payment, this value will be zero as we don't need to pay a fee to ourselves.
int64 total_amt = 3
The total amount of funds required to complete a payment over this route. This value includes the cumulative fees at each hop. As a result, the HTLC extended to the first-hop in the route will need to have at least this many satoshis, otherwise the route will fail at an intermediate node due to an insufficient amount of fees.
repeated hops = 4
Contains details concerning the specific forwarding details at each hop.
int64 total_fees_msat = 5
The total fees in millisatoshis.
int64 total_amt_msat = 6
The total amount in millisatoshis.
int64 first_hop_amount_msat = 7
The actual on-chain amount that was sent out to the first hop. This value is only different from the total_amt_msat field if this is a custom channel payment and the value transported in the HTLC is different from the BTC amount in the HTLC. If this value is zero, then this is an old payment that didn't have this value yet and can be ignored.
