SYNOPSIS
|
|||
|
|
--------
|
|||
|
|
|
|||
|
|
**invoice** *msatoshi* *label* *description* \[*expiry*\]

|
|
DESCRIPTION
|
|||
|
|
-----------
|
|||
|
|
|
|||
|
|
The **invoice** RPC command creates the expectation of a payment of a
|
|||
|
|
given amount of milli-satoshi: it returns a unique token which another
|
|||
|
|
lightning daemon can use to pay this invoice. This token includes a
|
|||
|
|
*route hint* description of an incoming channel with capacity to pay the
|
|||
|
|
invoice, if any exists.
|
|||
|
|
|
|||
|
|
The *msatoshi* parameter can be the string "any", which creates an
|
|||
|
|
invoice that can be paid with any amount. Otherwise it is in
|
|||
|
|
millisatoshi precision; it can be a whole number, or a whole number
|
|||
|
|
ending in *msat* or *sat*, or a number with three decimal places ending
|
|||
|
|
in *sat*, or a number with 1 to 11 decimal places ending in *btc*.
|
|||
|
|
|
|||
|
|
The *label* must be a unique string or number (which is treated as a
|
|||
|
|
string, so "01" is different from "1"); it is never revealed to other
|
|||
|
|
nodes on the lightning network, but it can be used to query the status
|
|||
|
|
of this invoice.
|
|||
|
|
|
|||
|
|
The *description* is a short description of purpose of payment, e.g. *1
|
|||
|
|
cup of coffee*. This value is encoded into the BOLT11 invoice and is
|
|||
|
|
viewable by any node you send this invoice to. It must be UTF-8, and
|
|||
|
|
cannot use *\\u* JSON escape codes.
|
|||
|
|
|
|||
|
|
The *expiry* is optionally the time the invoice is valid for; without a
|
|||
|
|
suffix it is interpreted as seconds, otherwise suffixes *s*, *m*, *h*,
|
|||
|
|
*d*, *w* indicate seconds, minutes, hours, days and weeks respectively.
|
|||
|
|
If no value is provided the default of 604800 (1w) is used.
|
|||
|
|
|
|||
|
|
The *fallbacks* array is one or more fallback addresses to include in
|
|||
|
|
the invoice (in order from most-preferred to least): note that these
|
|||
|
|
arrays are not currently tracked to fulfill the invoice.
|
|||
|
|
|
|||
|
|
The *preimage* is a 64-digit hex string to be used as payment preimage
|
|||
|
|
for the created invoice. By default, if unspecified, lightningd will
|
|||
|
|
generate a secure pseudorandom preimage seeded from an appropriate
|
|||
|
|
entropy source on your system. **IMPORTANT**: if you specify the
|
|||
|
|
*preimage*, you are responsible, to ensure appropriate care for
|
|||
|
|
generating using a secure pseudorandom generator seeded with sufficient
|
|||
|
|
entropy, and keeping the preimage secret. This parameter is an advanced
|
|||
|
|
feature intended for use with cutting-edge cryptographic protocols and
|
|||
|
|
should not be used unless explicitly needed.
|
|||
|
|
|
|||
|
|
If specified, *exposeprivatechannels* overrides the default route hint
|
|||
|
|
logic, which will use unpublished channels only if there are no
|
|||
|
|
published channels. If *true* unpublished channels are always considered
|
|||
|
|
as a route hint candidate; if *false*, never.
|
|||
|
|
|
|||
|
|
The route hint is selected from the set of incoming channels of which:
|
|||
|
|
peer’s balance minus their reserves is at least *msatoshi*, state is
|
|||
|
|
normal, the peer is connected and not a dead end (i.e. has at least one
|
|||
|
|
other public channel). The selection uses some randomness to prevent
|
|||
|
|
probing, but favors channels that become more balanced after the
|
|||
|
|
payment.
|
|||
|
|
|
|||
|
|
RETURN VALUE
|
|||
|
|
------------
|
|||
|
|
|
|||
|
|
On success, a hash is returned as *payment\_hash* to be given to the
|
|||
|
|
payer, and the *expiry\_time* as a UNIX timestamp. It also returns a
|
|||
|
|
BOLT11 invoice as *bolt11* to be given to the payer.
|
|||
|
|
|
|||
|
|
On failure, an error is returned and no invoice is created. If the
|
|||
|
|
lightning process fails before responding, the caller should use
|
|||
|
|
lightning-listinvoice(7) to query whether this invoice was created or
|
|||
|
|
not.
|
|||
|
|
|
|||
|
|
The following error codes may occur:
|
|||
|
|
- -1: Catchall nonspecific error.
|
|||
|
|
- 900: An invoice with the given *label* already exists.
|
|||
|
|
- 901: An invoice with the given *preimage* already exists.
|
|||
|
|
|
|||
|
|
One of the following warnings may occur (on success):
|
|||
|
|
- *warning\_offline* if no channel with a currently connected peer has
|
|||
|
|
the incoming capacity to pay this invoice
|
|||
|
|
- *warning\_capacity* if there is no channel that has both sufficient
|
|||
|
|
incoming capacity and has a peer that is publicly connected (i.e.
|
|||
|
|
not a dead end)
