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.

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. |
| 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. |
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. |
| 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. |
| recovery_window |
int32 |
recovery_window is an optional argument specifying the address lookahead when restoring a wallet seed. The recovery window applies to each invdividual 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. |

UnlockWallet
Simple RPC
UnlockWallet is used at startup of lnd to provide a password to unlock the wallet database.
# The unlock command is used to decrypt lnd's wallet state in order to
# start up. This command MUST be run after booting up lnd before it's
# able to carry out its duties. An exception is if a user is running with
# --noseedbackup, then a default passphrase will be used.
$ lncli unlock [command options] [arguments...]
# --recovery_window value address lookahead to resume recovery rescan, value should be non-zero -- To recover all funds, this should be greater than the maximum number of consecutive, unused addresses ever generated by the wallet. (default: 0)

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 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 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)

Simple RPC
SendMany handles a request for a transaction that creates multiple specified outputs in parallel. 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.
# Create and broadcast a transaction paying the specified amount(s) to the passed address(es).
# 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)

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.
# 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.
# 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)

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.
# 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 [time_limit]]
# --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)
# --time_limit value a relative deadline afterwhich the attempt should be abandoned
# --force after the time limit has passed, 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)

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
# The --debug_send flag is provided for usage *purely* in test
# environments. If specified, then the payment hash isn't required, as
# it'll use the hash of all zeroes. This mode allows one to quickly test
# payment connectivity without having to create an invoice at the
# destination.
$ lncli sendpayment [command options] dest amt payment_hash final_cltv_delta | --pay_req=[payment request]
# --dest value, -d value the compressed identity pubkey of the payment recipient
# --amt value, -a value number of satoshis to send (default: 0)
# --fee_limit value maximum fee allowed in satoshis when sendingthe payment (default: 0)
# --fee_limit_percent value percentage of the payment's amount used as themaximum fee allowed when sending the payment (default: 0)
# --payment_hash value, -r value the hash to use within the payment's HTLC
# --debug_send use the debug rHash when sending the HTLC
# --pay_req value a zpay32 encoded payment request to fulfill
# --final_cltv_delta value the number of blocks the last hop has to reveal the preimage (default: 0)
# --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

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
# a list of routes to attempt and the payment hash. This command can even
# be chained with the response to queryroutes. 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 routes:
# * using the --routes parameter to manually specify a JSON encoded
# set of routes in the format of the return value of queryroutes:
# (lncli sendtoroute --payment_hash=<pay_hash> --routes=<route>)
# * passing the routes as a positional argument:
# (lncli sendtoroute --payment_hash=pay_hash <route>)
# * or reading in the routes from stdin, which can allow chaining the
# response from queryroutes, or even read in a file with a set of
# pre-computed routes:
# (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="")
# --receipt value an optional cryptographic receipt of payment
# --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. |
| receipt |
bytes |
Deprecated. An optional cryptographic receipt of payment which is not implemented. |
| r_preimage |
bytes |
The hex-encoded preimage (32 byte) which will allow settling an incoming HTLC payable to this preimage |
| r_hash |
bytes |
The hash of the preimage |
| value |
int64 |
The value of this invoice in satoshis |
| settled |
bool |

| 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. |
| 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 |

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. |

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. The reversed flag is set by default in order to
# paginate backwards. If you wish to paginate forwards, you must
# explicitly set the flag to false. 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)
# --reversed if set, the invoices returned precede the given index_offset, allowing backwards pagination

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.

gRPC Response: PolicyUpdateResponse
This response has no parameters.
ForwardingHistory
Simple RPC
ForwardingHistory allows the caller to query the htlcswitch for a record of all HTLC’s 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 a start and end time aren't provided,
# then events over the past 24 hours are queried for.
# 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)
