lightning-fetchinvoice -- Command for fetch an invoice for an offer
|
|
===================================================================
|
|
|
|
SYNOPSIS
|
|
--------
|
|
|
|
**(WARNING: experimental-offers only)**
|
|
|
|
**fetchinvoice** *offer* \[*msatoshi*\] \[*quantity*\] \[*recurrence_counter*\] \[*recurrence_start*\] \[*recurrence_label*\] \[*timeout*\]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
The **fetchinvoice** RPC command contacts the issuer of an *offer* to get
|
|
an actual invoice that can be paid. It highlights any changes between the
|
|
offer and the returned invoice.
|
|
|
|
The offer must not contain *send_invoice*; see lightning-sendinvoice(7).
|
|
|
|
*msatoshi* is required if the *offer* does not specify
|
|
an amount at all, otherwise it is not allowed.
|
|
|
|
*quantity* is is required if the *offer* specifies
|
|
*quantity_min* or *quantity_max*, otherwise it is not allowed.
|
|
|
|
*recurrence_counter* is required if the *offer*
|
|
specifies *recurrence*, otherwise it is not allowed.
|
|
*recurrence_counter* should first be set to 0, and incremented for
|
|
each successive invoice in a given series.
|
|
|
|
*recurrence_start* is required if the *offer*
|
|
specifies *recurrence_base* with *start_any_period* set, otherwise it
|
|
is not allowed. It indicates what period number to start at.
|
|
|
|
*recurrence_label* is required if *recurrence_counter* is set, and
|
|
otherwise is not allowed. It must be the same as prior fetchinvoice
|
|
calls for the same recurrence, as it is used to link them together.
|
|
|
|
*timeout* is an optional timeout; if we don't get a reply before this
|
|
we fail (default, 60 seconds).
|
|
|
|
