.SH "NAME"
|
|
lightning-invoice \- Protocol for accepting payments\&.
|
|
.SH "SYNOPSIS"
|
|
.sp
|
|
\fBinvoice\fR \fImsatoshi\fR \fIlabel\fR \fIdescription\fR [\fIexpiry\fR]
|
|
.SH "DESCRIPTION"
|
|
.sp
|
|
The \fBinvoice\fR 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\&.
|
|
.sp
|
|
The \fImsatoshi\fR can be the string "any", which creates an invoice that can be paid with any amount\&.
|
|
.sp
|
|
The \fIlabel\fR 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\&.
|
|
.sp
|
|
The \fIdescription\fR is a short description of purpose of payment, e\&.g\&. \fI1 cup of coffee\fR\&. 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 \fI\eu\fR JSON escape codes\&.
|
|
.sp
|
|
The \fIexpiry\fR is optionally the number of seconds the invoice is valid for\&. If no value is provided the default of 3600 (1 Hour) is used\&.
|
|
.SH "RETURN VALUE"
|
|
.sp
|
|
On success, a hash is returned as \fIpayment_hash\fR to be given to the payer, and the \fIexpiry_time\fR as a UNIX timestamp\&. It also returns a BOLT11 invoice as \fIbolt11\fR 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\&.
|
|
.SH "AUTHOR"
|
|
.sp
|
|
Rusty Russell <rusty@rustcorp\&.com\&.au> is mainly responsible\&.
