NAME
syncthing-rest-api - 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 the input and output
data is in JSON format. The interface is subject to change.
API KEY
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 (add -k flag when using HTTPS with a
Syncthing generated or self signed certificate).
SYSTEM ENDPOINTS
GET /rest/system/browse
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.

GET /rest/system/config/insync
Deprecated since version v1.12.0: This endpoint still works as before but is deprecated. Use
rest-config-insync instead.
Returns whether the config is in sync, i.e. whether the running configuration is the same as that on
disk.
{
"configInSync": true
}
POST /rest/system/config
Deprecated since version v1.12.0: This endpoint still works as before but is deprecated. Use rest-config
instead.
Post the full contents of the configuration, 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 rest-config-insync to check if a restart is required.
This endpoint is the main point to control Syncthing, even if the change only concerns a very small part
of the config: The usual workflow is to get the config, modify the needed parts and post it again.
GET /rest/system/connections
NOTE:
Return format changed in 0.13.0.
Returns the list of configured devices and some metadata associated with them. The list also contains the
local device itself as not connected.

New in version 1.2.0: The lastDialStatus dictionary contains the last error (or null for success) for
each peer address that Syncthing has attempted to contact. The connectionServiceStatus entries gained
"error": null attributes where previously there would be no error attribute at all in the success case.
New in version 1.18.0: The discoveryStatus dictionary lists all configured discovery methods, not only
failed ones like the now deprecated discoveryErrors. Each entry is an object itself (for consistency
with other fields), where a null value for the error attribute means the method is running successfully.
This effectively deprecates the discoveryMethods attribute as well, which now always matches the number
of entries in discoveryStatus.
GET /rest/system/upgrade
Checks for a possible upgrade and returns an object describing the newest version and upgrade
possibility.
{
"latest": "v0.14.47",
"majorNewer": false,
"newer": true,
"running": "v0.14.46"

CONFIG ENDPOINTS
Config Endpoints
New in version 1.12.0.
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 /rest/config/restart-required to check if a restart is required.
For all endpoints supporting PATCH, 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 RawListenAddresses in options, which is an array of strings, sending {RawListenAddresses:
["tcp://10.0.0.2"]} will replace all existing listen addresses.
/rest/config
GET returns the entire config and PUT replaces it.
/rest/config/restart-required
GET returns whether a restart of Syncthing is required for the current config to take effect.
/rest/config/folders, /rest/config/devices
GET returns all folders respectively devices as an array. PUT takes an array and POST a single object. In
both cases if a given folder/device already exists, it’s replaced, otherwise a new one is added.
/rest/config/folders/*id*, /rest/config/devices/*id*
Put the desired folder- respectively device-ID in place of *id*. GET returns the folder/device for the
given ID, PUT replaces the entire config and PATCH replaces only the given child objects.
/rest/config/options, /rest/config/ldap, /rest/config/gui
GET returns the respective object, PUT replaces the entire object and PATCH replaces only the given child
objects.
CLUSTER ENDPOINTS
Concerns the mesh network structure.
DELETE /rest/cluster/pending/devices
New in version 1.18.0.
Remove records about a pending remote device which tried to connect. Valid values for the device
parameter are those from the corresponding /rest/cluster-pending-devices-get endpoint.
$ curl -X DELETE -H "X-API-Key: abc123" http://localhost:8384/rest/cluster/pending/devices?device=P56IOI7-MZJNU2Y-IQGDREY-DM2MGTI-MGL3BXN-PQ6W5BM-TBBZ4TJ-XZWICQ2
Returns status 200 and no content upon success, or status 500 and a plain text error on failure. A
/events/pendingdeviceschanged event will be generated in response.
For a more permanent effect, also for future connections from the same device ID, the device should be
ignored in the configuration instead.
GET /rest/cluster/pending/devices
New in version 1.13.0.
Lists remote devices which have tried to connect, but are not yet configured in our instance.

}
DELETE /rest/cluster/pending/folders
New in version 1.18.0.
Remove records about a pending folder announced from a remote device. Valid values for the folder and
device parameters are those from the corresponding /rest/cluster-pending-folders-get endpoint. The
device parameter is optional and affects announcements of this folder from the given device, or from any
device if omitted.
$ curl -X DELETE -H "X-API-Key: abc123" http://localhost:8384/rest/cluster/pending/folders?folder=cpkn4-57ysy&device=P56IOI7-MZJNU2Y-IQGDREY-DM2MGTI-MGL3BXN-PQ6W5BM-TBBZ4TJ-XZWICQ2
Returns status 200 and no content upon success, or status 500 and a plain text error on failure. A
/events/pendingfolderschanged event will be generated in response.
For a more permanent effect, also for future announcements of the same folder ID, the folder should be
ignored in the configuration instead.
GET /rest/cluster/pending/folders
New in version 1.13.0.
Lists folders which remote devices have offered to us, but are not yet shared from our instance to them.
Takes the optional device parameter to only return folders offered by a specific remote device. Other
offering devices are also omitted from the result.

DATABASE ENDPOINTS
GET /rest/db/browse
Returns the directory tree of the global model. Directories are always JSON objects (map/dictionary), and
files are always arrays of modification time and size. The first integer is the files modification time,
and the second integer is the file size.
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.

GET /rest/db/completion
Returns the completion percentage (0 to 100) and byte / item counts. Takes optional device and folder
parameters:
• folder specifies the folder ID to calculate completion for. An empty or absent folder parameter means
all folders as an aggregate.
• device specifies the device ID to calculate completion for. An empty or absent device parameter means
the local device.
If a device is specified but no folder, completion is calculated for all folders shared with that device.
Example Queries
Completion status for folder abcd-1234 on device I6KAH76-...-3PSROAU:
/rest/db/completion?folder=abcd-1234&device=I6KAH76-...-3PSROAU
Aggregated completion status for device I6KAH76-...-3PSROAU (all folders shared with them):
/rest/db/completion?device=I6KAH76-...-3PSROAU
Completion status for folder abcd-1234 on the local device:
/rest/db/completion?folder=abcd-1234
Aggregated completion status for all folders on the local device:

GET /rest/db/ignores
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/**"
]
}
POST /rest/db/ignores
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.
GET /rest/db/need
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:
1. progress has 15 items
2. queued has 3 items
3. rest has 12 items
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.

POST /rest/db/override
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
POST /rest/db/prio
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
POST /rest/db/revert
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
POST /rest/db/scan
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
GET /rest/db/status
Returns information about the current status of a folder.
Parameters: folder, the ID of a folder.

The various fields have the following meaning:
global*:
Data in the cluster latest version.
inSync*:
Data that is locally the same as the cluster latest version.
local*:
Data that is locally present, regardless of whether it’s the same or different version as the
cluster latest version.
need*: Data that is needed to become up to date with the cluster latest version (i.e., data that is out
of sync).
receiveOnlyChanged*:
Data that has changed locally in a receive only folder, and thus not been sent to the cluster.
invalid:
Deprecated, always empty.
pullErrors:
The number of files that failed to sync during the last sync operations.
sequence:
The current folder sequence number.
state: The current folder state.
stateChanged:
When the folder state last changed.
version:
Deprecated, equivalent to the sequence number.
NOTE:
This is an expensive call, increasing CPU and RAM usage on the device. Use sparingly.
EVENT ENDPOINTS
GET /rest/events
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.
STATISTICS ENDPOINTS
