.sp
Syncthing exposes a REST interface over HTTP on the GUI port. This is used by
the GUI (from Javascript) and can be used by other processes wishing to control
Syncthing. In most cases both the input and output data is in JSON format. The
interface is subject to change.
.SH API KEY
.sp
To use the REST API an API key must be set and used. The API key can be
generated in the GUI, or set in the \fBconfiguration/gui/apikey\fP element in
the configuration file. To use an API key, set the request header
\fBX\-API\-Key\fP to the API key value. For example, \fBcurl \-X POST \-H
"X\-API\-Key: abc123" http://localhost:8384/rest/...\fP can be used to invoke
with \fBcurl\fP (add \fB\-k\fP flag when using HTTPS with a Syncthing generated or self signed certificate).
.SH SYSTEM ENDPOINTS
.SS GET /rest/system/browse
.sp
Returns a list of directories matching the path given by the optional parameter
\fBcurrent\fP\&. The path can use \fI\%patterns as described in Go’s filepath package\fP <\fBhttps://golang.org/pkg/path/filepath/#Match\fP>\&. A ‘*’ will always be appended
to the given path (e.g. \fB/tmp/\fP matches all its subdirectories). If the option
\fBcurrent\fP is not given, filesystem root paths are returned.

.SH CONFIG ENDPOINTS
.SS Config Endpoints
.sp
New in version 1.12.0.

.sp
These endpoints facilitate access and modification of the configuration in a granular way. Config sent to the endpoints must be in the same
format as returned by the corresponding GET request. When posting the
configuration succeeds, the posted configuration is immediately applied, except
for changes that require a restart. Query \fI\%/rest/system/config/insync\fP to check if
a restart is required.
.sp
For all endpoints supporting \fBPATCH\fP, it takes the existing config and
unmarshals the given JSON object on top of it. This means all child objects will
replace the existing objects, not extend them. For example for
\fBRawListenAddresses\(ga in options, which is an array of strings, sending
\(ga\(ga{RawListenAddresses: ["tcp://10.0.0.2"]\fP will replace all existing listen
addresses.
.SS /rest/config
.sp
\fBGET\fP returns the entire config and \fBPUT\fP replaces it.
.SS /rest/system/config/insync
.sp
\fBGET\fP returns whether the config is in sync, i.e. whether the running configuration is
the same as that on disk or if a restart is required.
.SS /rest/config/folders, /rest/config/devices
.sp
\fBGET\fP returns all folders respectively devices as an array. \fBPUT\fP takes an array and
\fBPOST\fP a single object. In both cases if a given folder/device already exists,
it’s replaced, otherwise a new one is added.
.SS /rest/config/folders/*id*, /rest/config/devices/*id*
.sp
Put the desired folder\- respectively device\-ID in place of *id*. \fBGET\fP
returns the folder/device for the given ID, \fBPUT\fP replaces the entire config
and \fBPATCH\fP replaces only the given child objects.
.SS /rest/config/options, /rest/config/ldap, /rest/config/gui
.sp
\fBGET\fP returns the respective object, \fBPUT\fP replaces the entire object and
\fBPATCH\fP replaces only the given child objects.

.SH EVENT ENDPOINTS
.SS GET /rest/events
.sp
To receive events, perform a HTTP GET of \fB/rest/events\fP\&.
.sp
To filter the event list, in effect creating a specific subscription for
only the desired event types, add a parameter
\fBevents=EventTypeA,EventTypeB,...\fP where the event types are any of the event\-types\&.
.sp
The optional parameter \fBsince=<lastSeenID>\fP sets the ID of the last event
you’ve already seen. Syncthing returns a JSON encoded array of event objects,
starting at the event just after the one with this last seen ID. The default
value is 0, which returns all events. 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. By default it times out after
60 seconds returning an empty array. The time out duration can be customized
with the optional parameter \fBtimeout=<seconds>\fP\&.
.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\&.
