REST API 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 …
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 configuration/gui/apikey element in the configuration file. To use an API key, set the request header X-API-Key to the API key value. For example, curl -X POST -H "X-API-Key: abc123" http://localhost:8384/rest/... can be used to invoke with curl.
Returns a list of directories matching the path given by the optional parameter current. The path can use patterns as described in Go’s filepath package <https://golang.org/pkg/path/filepath/#Match>. A ‘*’ will always be appended to the given path (e.g. /tmp/ matches all its subdirectories). If the option current is not given, filesystem root paths are returned.

The call takes one mandatory folder parameter and two optional parameters. Optional parameter levels defines how deep within the tree we want to dwell down (0 based, defaults to unlimited depth) Optional parameter prefix defines a prefix within the tree where to start building the structure.

Takes one parameter, folder, and returns the content of the .stignore as the ignore field. A second field, expanded, provides a list of strings which represent globbing patterns described by gobwas/glob (based on standard wildcards) that match the patterns in .stignore and all the includes. If appropriate these globs are prepended by the following modifiers: ! to negate the glob, (?i) to do case insensitive matching and (?d) to enable removing of ignored files in an otherwise empty directory.
{
"ignore": [
"(?i)/Backups"
],
"expanded": [
"(?i)Backups",
"(?i)Backups/**"
]
}
Expects a format similar to the output of GET call, but only containing the ignore field (expanded field should be omitted). It takes one parameter, folder, and either updates the content of the .stignore echoing it back as a response, or returns an error.
Takes one mandatory parameter, folder, and returns lists of files which are needed by this device in order for it to become in sync.
Furthermore takes an optional page and perpage arguments for pagination. Pagination happens, across the union of all needed files, that is - across all 3 sections of the response. For example, given the current need state is as follows:
If you issue a query with page=1 and perpage=10, only the progress section in the response will have 10 items. If you issue a request query with page=2 and perpage=10, progress section will have the last 5 items, queued section will have all 3 items, and rest section will have first 2 items. If you issue a query for page=3 and perpage=10, you will only have the last 10 items of the rest section.
In all these calls, total will be 30 to indicate the total number of available items.

NOTE:
Request override of a send only folder. Override means to make the local version latest, overriding changes made on other devices. This API call does nothing if the folder is not a send only folder.
Takes the mandatory parameter folder (folder ID).
curl -X POST -H X-API-key:... http://127.0.0.1:8384/rest/db/override?folder=default
Moves the file to the top of the download queue.
curl -X POST http://127.0.0.1:8384/rest/db/prio?folder=default&file=foo/bar
Response contains the same output as GET /rest/db/need
New in version 0.14.50.
Request revert of a receive only folder. Reverting a folder means to undo all local changes. This API call does nothing if the folder is not a receive only folder.
Takes the mandatory parameter folder (folder ID).
curl -X POST -H X-API-Key:... http://127.0.0.1:8384/rest/db/revert?folder=default
Request immediate scan. Takes the optional parameters folder (folder ID), sub (path relative to the folder root) and next (time in seconds). If folder is omitted or empty all folders are scanned. If sub is given, only this path (and children, in case it’s a directory) is scanned. The next argument delays Syncthing’s automated rescan interval for a given amount of seconds.
Requesting scan of a path that no longer exists, but previously did, is valid and will result in Syncthing noticing the deletion of the path in question.
Returns status 200 and no content upon success, or status 500 and a plain text error if an error occurred during scanning.
curl -X POST http://127.0.0.1:8384/rest/db/scan?folder=default&sub=foo/bar
Returns information about the current status of a folder.
Parameters: folder, the ID of a folder.

The various fields have the following meaning:
NOTE:
To receive events, perform a HTTP GET of /rest/events.
To filter the event list, in effect creating a specific subscription for only the desired event types, add a parameter events=EventTypeA,EventTypeB,... where the event types are any of the event-types.
The optional parameter since=<lastSeenID> 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.
If no new events are produced since <lastSeenID>, 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 timeout=seconds.
To receive only a limited number of events, add the limit=n parameter with a suitable value for n and only the last n events will be returned. This can be used to catch up with the latest event ID after a disconnection for example: /rest/events?since=0&limit=1.
Returns general statistics about devices. Currently, only contains the time the device was last seen.
$ curl -s http://localhost:8384/rest/stats/device | json

"lastSeen" : "2015-04-18T11:21:31.3256277+01:00"
}
