LND gRPC API Reference

Welcome to the gRPC API reference documentation for LND, the Lightning Network Daemon.

This site features the API documentation for lncli (CLI), Python, and JavaScript in order to communicate with a local lnd instance through gRPC. It is intended for those who already understand how to work with LND. If this is your first time or you need a refresher, you may consider perusing our LND developer site featuring a tutorial, resources and guides at dev.lightning.community.

The examples to the right assume that the there is a local lnd instance running and listening for gRPC connections on port 10009. LND_DIR will be used as a placeholder to denote the base directory of the lnd instance. By default, this is ~/.lnd on Linux and ~/Library/Application Support/Lnd on macOS.

At the time of writing this documentation, two things are needed in order to make a gRPC request to an lnd instance: a TLS/SSL connection and a macaroon used for RPC authentication. The examples to the right will show how these can be used in order to make a successful, secure, and authenticated gRPC request.

The original rpc.proto file from which the gRPC documentation was generated can be found here.

Alternatively, the REST documentation can be found here.

GenSeed

Simple RPC

GenSeed 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.

>>> ssl_creds = grpc.ssl_channel_credentials(cert)
>>> channel = grpc.secure_channel('localhost:10009', ssl_creds)
>>> stub = lnrpc.WalletUnlockerStub(channel)
>>> request = ln.GenSeedRequest(
        aezeed_passphrase=<bytes>,

}

gRPC Request: GenSeedRequest

Parameter	Type	Description
aezeed_passphrase	bytes	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.
seed_entropy	bytes	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.

gRPC Response: GenSeedResponse

Parameter	Type	Description
cipher_seed_mnemonic	array string	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.
enciphered_seed	bytes	enciphered_seed are the raw aezeed cipher seed bytes. This is the raw cipher text before run through our mnemonic encoding scheme.

InitWallet

Simple RPC

InitWallet 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.

gRPC Request: InitWalletRequest

Parameter	Type	Description
wallet_password	bytes	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.
cipher_seed_mnemonic	array string	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.
aezeed_passphrase	bytes	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.
recovery_window	int32	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.
channel_backups	ChanBackupSnapshot	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.

UnlockWallet

Simple RPC

UnlockWallet is used at startup of lnd to provide a password to unlock the wallet database.

SendCoins

Simple RPC

SendCoins executes a request to send coins to a particular address. Unlike SendMany, this RPC call only allows creating a single output at a time. If neither target_conf, or sat_per_byte are set, then the internal wallet will consult its fee model to determine a fee for the default confirmation target.

# Send amt coins in satoshis to the base58 or bech32 encoded bitcoin address addr.
# Fees used when sending the transaction can be specified via the --conf_target, or
# --sat_per_byte optional flags.
# Positional arguments and flags can be used interchangeably but not at the same time!

$ lncli sendcoins [command options] addr amt

# --addr value          the base58 or bech32 encoded bitcoin address to send coins to on-chain
# --sweepall            if set, then the amount field will be ignored, and all the wallet will attempt to sweep all outputs within the wallet to the target address
# --amt value           the number of bitcoin denominated in satoshis to send (default: 0)
# --conf_target value   (optional) the number of blocks that the transaction *should* confirm in, will be used for fee estimation (default: 0)
# --sat_per_byte value  (optional) a manual fee expressed in sat/byte that should be used when crafting the transaction (default: 0)

# The send-json-string' param decodes addresses and the amount to send
# respectively in the following format:
# '{"ExampleAddr": NumCoinsInSatoshis, "SecondAddr": NumCoins}'

$ lncli sendmany [command options] send-json-string [--conf_target=N] [--sat_per_byte=P]

# --conf_target value   (optional) the number of blocks that the transaction *should* confirm in, will be used for fee estimation (default: 0)
# --sat_per_byte value  (optional) a manual fee expressed in sat/byte that should be used when crafting the transaction (default: 0)

gRPC Request: OpenChannelRequest

Parameter	Type	Description
node_pubkey	bytes	The pubkey of the node to open a channel with. When using REST, this field must be encoded as base64.
node_pubkey_string	string	The hex encoded pubkey of the node to open a channel with. Deprecated now that the REST gateway supports base64 encoding of bytes fields.
local_funding_amount	int64	The number of satoshis the wallet should commit to the channel
push_sat	int64	The number of satoshis to push to the remote side as part of the initial commitment state
target_conf	int32	The target number of blocks that the funding transaction should be confirmed by.
sat_per_byte	int64	A manual fee rate set in sat/byte that should be used when crafting the funding transaction.
private	bool	Whether this channel should be private, not announced to the greater network.
min_htlc_msat	int64	The minimum value in millisatoshi we will require for incoming HTLCs on the channel.
remote_csv_delay	uint32	The delay we require on the remote's commitment transaction. If this is not set, it will be scaled automatically with the channel size.
min_confs	int32	The minimum number of confirmations each one of your outputs used for the funding transaction must satisfy.
spend_unconfirmed	bool	Whether unconfirmed outputs should be used as inputs for the funding transaction.
close_address	string	Close address is an optional address which specifies the address to which funds should be paid out to upon cooperative close. This field may only be set if the peer supports the option upfront feature bit (call listpeers to check). The remote peer will only accept cooperative closes to this address if it is set. Note: If this value is set on channel creation, you will not be able to cooperatively close out to a different address.
funding_shim	FundingShim	Funding shims are an optional argument that allow the caller to intercept certain funding functionality. For example, a shim can be provided to use a particular key for the commitment key (ideally cold) rather than use one that is generated by the wallet as normal, or signal that signing will be carried out in an interactive manner (PSBT based).

gRPC Response: ChannelPoint

Parameter	Type	Description
funding_txid_bytes	bytes	Txid of the funding transaction. When using REST, this field must be encoded as base64.
funding_txid_str	string	Hex-encoded string representing the byte-reversed hash of the funding transaction.
output_index	uint32	The index of the output of the funding transaction

OpenChannel

Response-streaming RPC

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.

# Attempt to open a new channel to an existing peer with the key node-key
# optionally blocking until the channel is 'open'.
# One can also connect to a node before opening a new channel to it by
# setting its host:port via the --connect argument. For this to work,
# the node_key must be provided, rather than the peer_id. This is optional.
# The channel will be initialized with local-amt satoshis local and push-amt
# satoshis for the remote node. Note that specifying push-amt means you give that
# amount to the remote node as part of the channel opening. Once the channel is open,
# a channelPoint (txid:vout) of the funding output is returned.
# If the remote peer supports the option upfront shutdown feature bit (query
# listpeers to see their supported feature bits), an address to enforce
# payout of funds on cooperative close can optionally be provided. Note that
# if you set this value, you will not be able to cooperatively close out to
# another address.
# One can manually set the fee to be used for the funding transaction via either
# the --conf_target or --sat_per_byte arguments. This is optional.

$ lncli openchannel [command options] node-key local-amt push-amt

# --node_key value          the identity public key of the target node/peer serialized in compressed format
# --connect value           (optional) the host:port of the target node
# --local_amt value         the number of satoshis the wallet should commit to the channel (default: 0)
# --push_amt value          the number of satoshis to give the remote side as part of the initial commitment state, this is equivalent to first opening a channel and sending the remote party funds, but done all in one step (default: 0)
# --block                   block and wait until the channel is fully open
# --conf_target value       (optional) the number of blocks that the transaction *should* confirm in, will be used for fee estimation (default: 0)
# --sat_per_byte value      (optional) a manual fee expressed in sat/byte that should be used when crafting the transaction (default: 0)
# --private                 make the channel private, such that it won't be announced to the greater network, and nodes other than the two channel endpoints must be explicitly told about it to be able to route through it
# --min_htlc_msat value     (optional) the minimum value we will require for incoming HTLCs on the channel (default: 0)
# --remote_csv_delay value  (optional) the number of blocks we will require our channel counterparty to wait before accessing its funds in case of unilateral close. If this is not set, we will scale the value according to the channel size (default: 0)
# --min_confs value         (optional) the minimum number of confirmations each one of your outputs used for the funding transaction must satisfy (default: 1)
# --close_address value     (optional) an address to enforce payout of our funds to on cooperative close. Note that if this value is set on channel open, you will *not* be able to cooperatively close to a different address.

gRPC Request: OpenChannelRequest

Parameter	Type	Description
node_pubkey	bytes	The pubkey of the node to open a channel with. When using REST, this field must be encoded as base64.
node_pubkey_string	string	The hex encoded pubkey of the node to open a channel with. Deprecated now that the REST gateway supports base64 encoding of bytes fields.
local_funding_amount	int64	The number of satoshis the wallet should commit to the channel
push_sat	int64	The number of satoshis to push to the remote side as part of the initial commitment state
target_conf	int32	The target number of blocks that the funding transaction should be confirmed by.
sat_per_byte	int64	A manual fee rate set in sat/byte that should be used when crafting the funding transaction.
private	bool	Whether this channel should be private, not announced to the greater network.
min_htlc_msat	int64	The minimum value in millisatoshi we will require for incoming HTLCs on the channel.
remote_csv_delay	uint32	The delay we require on the remote's commitment transaction. If this is not set, it will be scaled automatically with the channel size.
min_confs	int32	The minimum number of confirmations each one of your outputs used for the funding transaction must satisfy.
spend_unconfirmed	bool	Whether unconfirmed outputs should be used as inputs for the funding transaction.
close_address	string	Close address is an optional address which specifies the address to which funds should be paid out to upon cooperative close. This field may only be set if the peer supports the option upfront feature bit (call listpeers to check). The remote peer will only accept cooperative closes to this address if it is set. Note: If this value is set on channel creation, you will not be able to cooperatively close out to a different address.
funding_shim	FundingShim	Funding shims are an optional argument that allow the caller to intercept certain funding functionality. For example, a shim can be provided to use a particular key for the commitment key (ideally cold) rather than use one that is generated by the wallet as normal, or signal that signing will be carried out in an interactive manner (PSBT based).

gRPC Response: OpenStatusUpdate (Streaming)

Parameter	Type	Description
chan_pending	PendingUpdate
chan_open	ChannelOpenUpdate
pending_chan_id	bytes	The pending channel ID of the created channel. This value may be used to further the funding flow manually via the FundingStateStep method.

FundingStateStep

Simple RPC

FundingStateStep 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.

gRPC Request: FundingTransitionMsg

Parameter	Type	Description
shim_register	FundingShim	The funding shim to regsiter. This should be used before any channel funding has began by the remote party, as it is intended as a prepatory step for the full channel funding.
shim_cancel	FundingShimCancel	Used to cancel an existing registered funding shim.

gRPC Response: FundingStateStepResp

This response has no parameters.

ChannelAcceptor

Bidirectional-streaming RPC

ChannelAcceptor 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.

CloseChannel

Response-streaming RPC

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.

# Close an existing channel. The channel can be closed either cooperatively,
# or unilaterally (--force).
# A unilateral channel closure means that the latest commitment
# transaction will be broadcast to the network. As a result, any settled
# funds will be time locked for a few blocks before they can be spent.
# In the case of a cooperative closure, one can manually set the fee to
# be used for the closing transaction via either the --conf_target or
# --sat_per_byte arguments. This will be the starting value used during
# fee negotiation. This is optional.
# In the case of a cooperative closure, one can manually set the address
# to deliver funds to upon closure. This is optional, and may only be used
# if an upfront shutdown address has not already been set. If neither are
# set the funds will be delivered to a new wallet address.
# To view which funding_txids/output_indexes can be used for a channel close,
# see the channel_point values within the listchannels command output.
# The format for a channel_point is 'funding_txid:output_index'.

$ lncli closechannel [command options] funding_txid [output_index]

# --funding_txid value   the txid of the channel's funding transaction
# --output_index value   the output index for the funding output of the funding transaction (default: 0)
# --force                attempt an uncooperative closure
# --block                block until the channel is closed
# --conf_target value    (optional) the number of blocks that the transaction *should* confirm in, will be used for fee estimation (default: 0)
# --sat_per_byte value   (optional) a manual fee expressed in sat/byte that should be used when crafting the transaction (default: 0)
# --delivery_addr value  (optional) an address to deliver funds upon cooperative channel closing, may only be used if an upfront shutdown addresss is notalready set

gRPC Request: CloseChannelRequest

Parameter	Type	Description
channel_point	ChannelPoint	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.
force	bool	If true, then the channel will be closed forcibly. This means the current commitment transaction will be signed and broadcast.
target_conf	int32	The target number of blocks that the closure transaction should be confirmed by.
sat_per_byte	int64	A manual fee rate set in sat/byte that should be used when crafting the closure transaction.
delivery_address	string	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.

SendPayment

Bidirectional-streaming RPC

SendPayment dispatches a bi-directional streaming RPC for sending payments through the Lightning Network. A single RPC invocation creates a persistent bi-directional stream allowing clients to rapidly send payments through the Lightning Network with a single persistent connection.

# Send a payment over Lightning. One can either specify the full
# parameters of the payment, or just use a payment request which encodes
# all the payment details.
# If payment isn't manually specified, then only a payment request needs
# to be passed using the --pay_req argument.
# If the payment *is* manually specified, then all four alternative
# arguments need to be specified in order to complete the payment:
# * --dest=N
# * --amt=A
# * --final_cltv_delta=T
# * --payment_hash=H

$ lncli sendpayment [command options] dest amt payment_hash final_cltv_delta | --pay_req=[payment request]

# --pay_req value                 a zpay32 encoded payment request to fulfill
# --fee_limit value               maximum fee allowed in satoshis when sending the payment (default: 0)
# --fee_limit_percent value       percentage of the payment's amount used as the maximum fee allowed when sending the payment (default: 0)
# --cltv_limit value              the maximum time lock that may be used for this payment (default: 0)
# --last_hop value                pubkey of the last hop (penultimate node in the path) to route through for this payment
# --outgoing_chan_id value        short channel id of the outgoing channel to use for the first hop of the payment (default: 0)
# --force, -f                     will skip payment request confirmation
# --allow_self_payment            allow sending a circular payment to self
# --data value                    attach custom data to the payment. The required format is: <record_id>=<hex_value>,<record_id>=<hex_value>,.. For example: --data 3438382=0a21ff. Custom record ids start from 65536.
# --dest value, -d value          the compressed identity pubkey of the payment recipient
# --amt value, -a value           number of satoshis to send (default: 0)
# --payment_hash value, -r value  the hash to use within the payment's HTLC
# --final_cltv_delta value        the number of blocks the last hop has to reveal the preimage (default: 0)

Parameter	Type	Description
dest	bytes	The identity pubkey of the payment recipient. When using REST, this field must be encoded as base64.
dest_string	string	The hex-encoded identity pubkey of the payment recipient. Deprecated now that the REST gateway supports base64 encoding of bytes fields.
amt	int64	The amount to send expressed in satoshis. The fields amt and amt_msat are mutually exclusive.
amt_msat	int64	The amount to send expressed in millisatoshis. The fields amt and amt_msat are mutually exclusive.
payment_hash	bytes	The hash to use within the payment's HTLC. When using REST, this field must be encoded as base64.
payment_hash_string	string	The hex-encoded hash to use within the payment's HTLC. Deprecated now that the REST gateway supports base64 encoding of bytes fields.
payment_request	string	A bare-bones invoice for a payment within the Lightning Network. With the details of the invoice, the sender has all the data necessary to send a payment to the recipient.
final_cltv_delta	int32	The CLTV delta from the current height that should be used to set the timelock for the final hop.
fee_limit	FeeLimit	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.

SendToRoute

Bidirectional-streaming RPC

SendToRoute is a bi-directional streaming RPC for sending payment through the Lightning Network. This method differs from SendPayment in that it allows users to specify a full route manually. This can be used for things like rebalancing, and atomic swaps.

# Send a payment over Lightning using a specific route. One must specify
# the route to attempt and the payment hash. This command can even
# be chained with the response to queryroutes or buildroute. This command
# can be used to implement channel rebalancing by crafting a self-route,
# or even atomic swaps using a self-route that crosses multiple chains.
# There are three ways to specify a route:
# * using the --routes parameter to manually specify a JSON encoded
# route in the format of the return value of queryroutes or
# buildroute:
# (lncli sendtoroute --payment_hash=<pay_hash> --routes=<route>)
# * passing the route as a positional argument:
# (lncli sendtoroute --payment_hash=pay_hash <route>)
# * or reading in the route from stdin, which can allow chaining the
# response from queryroutes or buildroute, or even read in a file
# with a pre-computed route:
# (lncli queryroutes --args.. | lncli sendtoroute --payment_hash= -
# notice the '-' at the end, which signals that lncli should read
# the route in from stdin

$ lncli sendtoroute [command options] [arguments...]

# --payment_hash value, --pay_hash value  the hash to use within the payment's HTLC
# --routes value, -r value                a json array string in the format of the response of queryroutes that denotes which routes to use

AddInvoice

Simple RPC

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.

# Add a new invoice, expressing intent for a future payment.
# Invoices without an amount can be created by not supplying any
# parameters or providing an amount of 0. These invoices allow the payee
# to specify the amount of satoshis they wish to send.

$ lncli addinvoice [command options] value preimage

# --memo value              a description of the payment to attach along with the invoice (default="")
# --preimage value          the hex-encoded preimage (32 byte) which will allow settling an incoming HTLC payable to this preimage. If not set, a random preimage will be created.
# --amt value               the amt of satoshis in this invoice (default: 0)
# --description_hash value  SHA-256 hash of the description of the payment. Used if the purpose of payment cannot naturally fit within the memo. If provided this will be used instead of the description(memo) field in the encoded invoice.
# --fallback_addr value     fallback on-chain address that can be used in case the lightning payment fails
# --expiry value            the invoice's expiry time in seconds. If not specified an expiry of 3600 seconds (1 hour) is implied. (default: 0)
# --private                 encode routing hints in the invoice with private channels in order to assist the payer in reaching you

gRPC Request: Invoice

Parameter	Type	Description
memo	string	An optional memo to attach along with the invoice. Used for record keeping purposes for the invoice's creator, and will also be set in the description field of the encoded payment request if the description_hash field is not being used.
r_preimage	bytes	The hex-encoded preimage (32 byte) which will allow settling an incoming HTLC payable to this preimage. When using REST, this field must be encoded as base64.
r_hash	bytes	The hash of the preimage. When using REST, this field must be encoded as base64.
value	int64	The value of this invoice in satoshis The fields value and value_msat are mutually exclusive.
value_msat	int64	The value of this invoice in millisatoshis The fields value and value_msat are mutually exclusive.
settled	bool	Whether this invoice has been fulfilled
creation_date	int64	When this invoice was created
settle_date	int64	When this invoice was settled
payment_request	string	A bare-bones invoice for a payment within the Lightning Network. With the details of the invoice, the sender has all the data necessary to send a payment to the recipient.
description_hash	bytes	Hash (SHA-256) of a description of the payment. Used if the description of payment (memo) is too long to naturally fit within the description field of an encoded payment request. When using REST, this field must be encoded as base64.
expiry	int64	Payment request expiry time in seconds. Default is 3600 (1 hour).
fallback_addr	string	Fallback on-chain address.
cltv_expiry	uint64	Delta to use for the time-lock of the CLTV extended to the final hop.
route_hints	array RouteHint	Route hints that can each be individually used to assist in reaching the invoice's destination.
private	bool	Whether this invoice should include routing hints for private channels.
add_index	uint64	The "add" index of this invoice. Each newly created invoice will increment this index making it monotonically increasing. Callers to the SubscribeInvoices call can use this to instantly get notified of all added invoices with an add_index greater than this one.
settle_index	uint64	The "settle" index of this invoice. Each newly settled invoice will increment this index making it monotonically increasing. Callers to the SubscribeInvoices call can use this to instantly get notified of all settled invoices with an settle_index greater than this one.
amt_paid	int64	Deprecated, use amt_paid_sat or amt_paid_msat.
amt_paid_sat	int64	The amount that was accepted for this invoice, in satoshis. This will ONLY be set if this invoice has been settled. We provide this field as if the invoice was created with a zero value, then we need to record what amount was ultimately accepted. Additionally, it's possible that the sender paid MORE that was specified in the original invoice. So we'll record that here as well.
amt_paid_msat	int64	The amount that was accepted for this invoice, in millisatoshis. This will ONLY be set if this invoice has been settled. We provide this field as if the invoice was created with a zero value, then we need to record what amount was ultimately accepted. Additionally, it's possible that the sender paid MORE that was specified in the original invoice. So we'll record that here as well.
state	InvoiceState	The state the invoice is in.
htlcs	array InvoiceHTLC	List of HTLCs paying to this invoice [EXPERIMENTAL].
features	array FeaturesEntry	List of features advertised on the invoice.
is_keysend	bool	Indicates if this invoice was a spontaneous payment that arrived via keysend [EXPERIMENTAL].

gRPC Response: AddInvoiceResponse

Parameter	Type	Description
r_hash	bytes
payment_request	string	A bare-bones invoice for a payment within the Lightning Network. With the details of the invoice, the sender has all the data necessary to send a payment to the recipient.
add_index	uint64	The "add" index of this invoice. Each newly created invoice will increment this index making it monotonically increasing. Callers to the SubscribeInvoices call can use this to instantly get notified of all added invoices with an add_index greater than this one.

ListInvoices

Simple RPC

ListInvoices returns a list of all the invoices currently stored within the database. Any active debug invoices are ignored. It has full support for paginated responses, allowing users to query for specific invoices through their add_index. This can be done by using either the first_index_offset or last_index_offset fields included in the response as the index_offset of the next request. By default, the first 100 invoices created will be returned. Backwards pagination is also supported through the Reversed flag.

# This command enables the retrieval of all invoices currently stored
# within the database. It has full support for paginationed responses,
# allowing users to query for specific invoices through their add_index.
# This can be done by using either the first_index_offset or
# last_index_offset fields included in the response as the index_offset of
# the next request. Backward pagination is enabled by default to receive
# current invoices first. If you wish to paginate forwards, set the
# paginate-forwards flag.  If none of the parameters are specified, then
# the last 100 invoices will be returned.
# For example: if you have 200 invoices, "lncli listinvoices" will return
# the last 100 created. If you wish to retrieve the previous 100, the
# first_offset_index of the response can be used as the index_offset of
# the next listinvoices request.

$ lncli listinvoices [command options] [arguments...]

# --pending_only        toggles if all invoices should be returned, or only those that are currently unsettled
# --index_offset value  the index of an invoice that will be used as either the start or end of a query to determine which invoices should be returned in the response (default: 0)
# --max_invoices value  the max number of invoices to return (default: 0)
# --paginate-forwards   if set, invoices succeeding the index_offset will be returned

SubscribeInvoices

Response-streaming RPC

SubscribeInvoices returns a uni-directional stream (server -> client) for notifying the client of newly added/settled invoices. The caller can optionally specify the add_index and/or the settle_index. If the add_index is specified, then we'll first start by sending add invoice events for all invoices with an add_index greater than the specified value. If the settle_index is specified, the next, we'll send out all settle events for invoices with a settle_index greater than the specified value. One or both of these fields can be set. If no fields are set, then we'll only send out the latest add/settle events.

DescribeGraph

Simple RPC

DescribeGraph returns a description of the latest graph state from the point of view of the node.

gRPC Request: QueryRoutesRequest

Parameter	Type	Description
pub_key	string	The 33-byte hex-encoded public key for the payment destination
amt	int64	The amount to send expressed in satoshis. The fields amt and amt_msat are mutually exclusive.
amt_msat	int64	The amount to send expressed in millisatoshis. The fields amt and amt_msat are mutually exclusive.
final_cltv_delta	int32	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.
fee_limit	FeeLimit	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.
ignored_nodes	array bytes	A list of nodes to ignore during path finding. When using REST, these fields must be encoded as base64.
ignored_edges	array EdgeLocator	Deprecated. A list of edges to ignore during path finding.
source_pub_key	string	The source node where the request route should originated from. If empty, self is assumed.
use_mission_control	bool	If set to true, edge probabilities from mission control will be used to get the optimal route.
ignored_pairs	array NodePair	A list of directed node pairs that will be ignored during path finding.
cltv_limit	uint32	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.
dest_custom_records	array DestCustomRecordsEntry	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 recrods, and 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.
outgoing_chan_id	uint64	The channel id of the channel that must be taken to the first hop. If zero, any channel may be used.
last_hop_pubkey	bytes	The pubkey of the last hop of the route. If empty, any hop may be used.
route_hints	array RouteHint	Optional route hints to reach the destination through private channels.
dest_features	array FeatureBit	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.

gRPC Response: QueryRoutesResponse

Parameter	Type	Description
routes	array Route	The route that results from the path finding operation. This is still a repeated field to retain backwards compatibility.
success_prob	double	The success probability of the returned route based on the current mission control state. [EXPERIMENTAL]

DebugLevel

Simple RPC

DebugLevel allows a caller to programmatically set the logging verbosity of lnd. The logging can be targeted according to a coarse daemon-wide logging level, or in a granular fashion to specify the logging for a target sub-system.

# Logging level for all subsystems {trace, debug, info, warn, error, critical, off}
# You may also specify <subsystem>=<level>,<subsystem2>=<level>,... to set the log level for individual subsystems
# Use show to list available subsystems

$ lncli debuglevel [command options] [arguments...]

# --show         if true, then the list of available sub-systems will be printed out
# --level value  the level specification to target either a coarse logging level, or granular set of specific sub-systems with logging levels for each

ForwardingHistory

Simple RPC

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. If no time-range is specified, then the first chunk of the past 24 hrs of forwarding history are returned. 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.

# Query the HTLC switch's internal forwarding log for all completed
# payment circuits (HTLCs) over a particular time range (--start_time and
# --end_time). The start and end times are meant to be expressed in
# seconds since the Unix epoch. If --start_time isn't provided,
# then 24 hours ago is used.  If --end_time isn't provided,
# then the current time is used.
# The max number of events returned is 50k. The default number is 100,
# callers can use the --max_events param to modify this value.
# Finally, callers can skip a series of events using the --index_offset
# parameter. Each response will contain the offset index of the last
# entry. Using this callers can manually paginate within a time slice.

$ lncli fwdinghistory [command options] start_time [end_time] [index_offset] [max_events]

# --start_time value    the starting time for the query, expressed in seconds since the unix epoch (default: 0)
# --end_time value      the end time for the query, expressed in seconds since the unix epoch (default: 0)
# --index_offset value  the number of events to skip (default: 0)
# --max_events value    the max number of events to return (default: 0)

index_offset	uint32	Index offset is the offset in the time series to start at. As each response can only contain 50k records, callers can use this to skip around within a packed time series.
num_max_events	uint32	The max number of events to return in the response to this query.

gRPC Response: ForwardingHistoryResponse

Parameter	Type	Description
forwarding_events	array ForwardingEvent	A list of forwarding events from the time slice of the time series specified in the request.
last_offset_index	uint32	The index of the last time in the set of returned forwarding events. Can be used to seek further, pagination style.

ExportChannelBackup

Simple RPC

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.

# This command allows a user to export a Static Channel Backup (SCB) for
# a selected channel. SCB's are encrypted backups of a channel's initial
# state that are encrypted with a key derived from the seed of a user. In
# the case of partial or complete data loss, the SCB will allow the user
# to reclaim settled funds in the channel at its final state. The
# exported channel backups can be restored at a later time using the
# restorechanbackup command.
# This command will return one of two types of channel backups depending
# on the set of passed arguments:
# * If a target channel point is specified, then a single channel
# backup containing only the information for that channel will be
# returned.
# * If the --all flag is passed, then a multi-channel backup will be
# returned. A multi backup is a single encrypted blob (displayed in
# hex encoding) that contains several channels in a single cipher
# text.
# Both of the backup types can be restored using the restorechanbackup
# command.

$ lncli exportchanbackup [command options] [chan_point] [--all] [--output_file]

# --chan_point value   the target channel to obtain an SCB for
# --all                if specified, then a multi backup of all active channels will be returned
# --output_file value  if specified, then rather than printing a JSON output
# of the static channel backup, a serialized version of
# the backup (either Single or Multi) will be written to
# the target file, this is the same format used by lnd in
# its channels.backup file

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. If we are able to unpack the backup, then the new channel will be shown under listchannels, as well as pending channels.

# Allows a user to restore a Static Channel Backup (SCB) that was
# obtained either via the exportchanbackup command, or from lnd's
# automatically manged channels.backup file. This command should be used
# if a user is attempting to restore a channel due to data loss on a
# running node restored with the same seed as the node that created the
# channel. If successful, this command will allows the user to recover
# the settled funds stored in the recovered channels.
# The command will accept backups in one of three forms:
# * A single channel packed SCB, which can be obtained from
# exportchanbackup. This should be passed in hex encoded format.
# * A packed multi-channel SCB, which couples several individual
# static channel backups in single blob.
# * A file path which points to a packed multi-channel backup within a
# file, using the same format that lnd does in its channels.backup
# file.

$ lncli restorechanbackup [command options] [--single_backup] [--multi_backup] [--multi_file=

# --single_backup value  a hex encoded single channel backup obtained from exportchanbackup
# --multi_backup value   a hex encoded multi-channel backup obtained from exportchanbackup
# --multi_file value     the path to a multi-channel back up file

SubscribeChannelBackups

Response-streaming RPC

SubscribeChannelBackups allows a client to sub-subscribe to the most up to date information concerning the state of all channel backups. Each time a new channel is added, we return the new set of channels, along with a multi-chan backup containing the backup info for all channels. Each time a channel is closed, we send a new update, which contains new new chan back ups, but the updated set of encrypted multi-chan backups with the closed channel(s) removed.

BakeMacaroon

Simple RPC

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.

# Bake a new macaroon that grants the provided permissions and
# optionally adds restrictions (timeout, IP address) to it.
# The new macaroon can either be shown on command line in hex serialized
# format or it can be saved directly to a file using the --save_to
# argument.
# A permission is a tuple of an entity and an action, separated by a
# colon. Multiple operations can be added as arguments, for example:
# lncli bakemacaroon info:read invoices:write foo:bar

$ lncli bakemacaroon [command options] [--save_to=] [--timeout=] [--ip_address=] permissions...

# --save_to value     save the created macaroon to this file using the default binary format
# --timeout value     the number of seconds the macaroon will be valid before it times out (default: 0)
# --ip_address value  the IP address the macaroon will be bound to

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.
channel_backups	ChanBackupSnapshot	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.

amt_paid	int64	Deprecated, use amt_paid_sat or amt_paid_msat.
amt_paid_sat	int64	The amount that was accepted for this invoice, in satoshis. This will ONLY be set if this invoice has been settled. We provide this field as if the invoice was created with a zero value, then we need to record what amount was ultimately accepted. Additionally, it's possible that the sender paid MORE that was specified in the original invoice. So we'll record that here as well.
amt_paid_msat	int64	The amount that was accepted for this invoice, in millisatoshis. This will ONLY be set if this invoice has been settled. We provide this field as if the invoice was created with a zero value, then we need to record what amount was ultimately accepted. Additionally, it's possible that the sender paid MORE that was specified in the original invoice. So we'll record that here as well.
