NOTIFICATIONS
|
||
|
|
-------------
|
||
|
|
|
||
|
|
Notifications are JSON-RPC objects without an *id* field. *lightningd* sends
|
||
|
|
notifications (once enabled with this *notifications* command) with a *params*
|
||
|
|
*id* field indicating which command the notification refers to.
|
||
|
|
|
||
|
|
Implementations should ignore notifications without an *id* parameter, or
|
||
|
|
unknown *method*.
|
||
|
|
|
||
|
|
Common *method*s include:
|
||
|
|
|
||
|
|
- *message*: param *message*: a descriptional string indicating something
|
||
|
|
which occurred relating to the command. Param *level* indicates the level,
|
||
|
|
as per lightning-getlog(7): *info* and *debug* are typical.
|
||
|
|
- *progress*: param *num* and *total*, where *num* starts at 0 and is always
|
||
|
|
less than *total*. Optional param *stage* with fields *num* and *total*,
|
||
|
|
indicating what stage we are progressing through.
|
||
|
|
|
||
|
|
RETURN VALUE
|
||
|
|
------------
|
||
|
|
|
||
|
|
On success, an empty object will be returned, and if the level was
|
||
|
|
*true*, notifications will be forwarded from then on.
|
||
|
|
|
||
|
|
On failure, one of the following error codes may be returned:
|
||
|
|
|
||
|
|
- -32602: Error in given parameters.
