NAME
|
|
----
|
|
lightning-sendpay - Protocol for sending a payment via a route.
|
|
|
|
SYNOPSIS
|
|
--------
|
|
*sendpay* 'route' 'hash'
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
The *sendpay* RPC command attempts to send funds associated with the
|
|
given 'hash', along a route to the final destination in the route.
|
|
|
|
Generally, a client would call getroute(7) to resolve a route, then
|
|
use *sendpay* to send it. If it fails, it would call getroute(7)
|
|
again to retry.
|
|
|
|
The response will occur when the payment fails or succeeds. Once a
|
|
payment has succeeded, calls to *sendpay* with the same 'hash' will
|
|
fail; this prevents accidental multiple payments.
|
|
|
|
RETURN VALUE
|
|
------------
|
|
|
|
On success, a 'preimage' hex string is returned as proof that the
|
|
destination received the payment. The 'preimage' will SHA256 to the
|
|
'hash' given by the caller.
|
|
|
|
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.
