.SH DESCRIPTION
.sp
Syncthing provides a simple long polling interface for exposing events from the
core utility towards a GUI.
.sp
To receive events, perform a HTTP GET of \fB/rest/events?since=<lastSeenID>\fP,
where \fB<lastSeenID>\fP is the ID of the last event you\(aqve already seen or zero.
Syncthing returns a JSON encoded array of event objects, starting at the event
just after the one with the last seen ID. There is a limit to the number of
events buffered, so if the rate of events is high or the time between polling
calls is long some events might be missed. This can be detected by noting a
discontinuity in the event IDs.
.sp
If no new events are produced since \fB<lastSeenID>\fP, the HTTP call blocks and
waits for new events to happen before returning, or if no new events are
produced within 60 seconds, times out.
.sp
To receive only a limited number of events, add the \fBlimit=n\fP parameter with a
suitable value for \fBn\fP and only the \fIlast\fP \fBn\fP events will be returned. This
can be used to catch up with the latest event ID after a disconnection for
example: \fB/rest/events?since=0&limit=1\fP\&.
.SH EVENT STRUCTURE
.sp
Each event is represented by an object similar to the following:

A unique ID for this event on the events API. It always increases by 1: the first
event generated has id \fB1\fP, the next has id \fB2\fP etc. If this increases by
more than 1, then one or more events have been skipped by the events API.

A global ID for this event, across the events API, the audit log, and any other

than or equal to the id.
