.SH "NAME"
|
|
lightning-waitsendpay \- Protocol for sending a payment via a route\&.
|
|
.SH "SYNOPSIS"
|
|
.sp
|
|
\fBwaitsendpay\fR \fIpayment_hash\fR [\fItimeout\fR]
|
|
.SH "DESCRIPTION"
|
|
.sp
|
|
The \fBwaitsendpay\fR RPC command polls or waits for the status of an outgoing payment that was initiated by a previous \fBsendpay\fR invocation\&.
|
|
.sp
|
|
Optionally the client may provide a \fItimeout\fR, an integer in seconds, for this RPC command to return\&. If the \fItimeout\fR is provided and the given amount of time passes without the payment definitely succeeding or definitely failing, this command returns with a 200 error code (payment still in progress)\&. If \fItimeout\fR is not provided this call will wait indefinitely\&.
|
|
.sp
|
|
Indicating a \fItimeout\fR of 0 effectively makes this call a pollable query of the status of the payment\&.
|
|
.sp
|
|
If the payment completed with success, this command returns with success\&. Otherwise, if the payment completed with failure, this command returns an error\&.
|
|
.SH "RETURN VALUE"
|
|
.sp
|
|
On success, an object similar to the output of \fBlistpayments\fR will be returned\&. This object will have a \fIstatus\fR field that is the string \fI"complete"\fR\&.
|
|
.sp
|
|
On error, if the error occurred from a node other than the final destination, the route table will be updated so that getroute(7) should return an alternate route (if any)\&. An error from the final destination implies the payment should not be retried\&.
|
|
.sp
|
|
The following error codes may occur:
|
|
