lightning-waitanyinvoice -- Command for waiting for payments
============================================================
SYNOPSIS
--------
**waitanyinvoice** \[*lastpay\_index*\] \[*timeout*\]
DESCRIPTION
-----------
The **waitanyinvoice** RPC command waits until an invoice is paid, then
returns a single entry as per **listinvoice**. It will not return for
any invoices paid prior to or including the *lastpay\_index*.
This is usually called iteratively: once with no arguments, then
repeatedly with the returned *pay\_index* entry. This ensures that no
paid invoice is missed.
The *pay\_index* is a monotonically-increasing number assigned to an
invoice when it gets paid. The first valid *pay\_index* is 1; specifying
*lastpay\_index* of 0 equivalent to not specifying a *lastpay\_index*.
Negative *lastpay\_index* is invalid.
If *timeout* is specified, wait at most that number of seconds, which
must be an integer.
If the specified *timeout* is reached, this command will return with an
error.
You can specify this to 0 so that **waitanyinvoice** will return
immediately with an error if no pending invoice is available yet.
If unspecified, this command will wait indefinitely.
RETURN VALUE
------------
On success, an invoice description will be returned as per
lightning-listinvoice(7): *complete* will always be *true*.
Possible errors are:
* 904.
The *timeout* was reached without an invoice being paid.
