SYNCTHING-REST-API(7)

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, or set it as a Bearer token in the Authorization header. For example, curl -X POST -H "X-API-Key: abc123" http://localhost:8384/rest/... or curl -X POST -H "Authorization: Bearer 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).

One exception to this requirement is /rest/noauth, you do not need an API key to use those endpoints. This way third-party devices and services can do simple calls that don’t expose sensitive information without having to expose your API key.

RESULT PAGINATION

Some GET endpoints take optional page and perpage arguments for pagination. No more than perpage (defaults to 65536 if not given) result entries are returned in an array. To access further entries, passing the page parameter will advance in the results by that many pages. The actually used parameters are always returned as attributes in the response object.

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://pkg.go.dev/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.

    $ curl -H "X-API-Key: yourkey" localhost:8384/rest/system/browse | json_pp
    [
        "/"
    ]
    $ curl -H "X-API-Key: yourkey" localhost:8384/rest/system/browse?current=/var/ | json_pp
    [
        "/var/backups/",
        "/var/cache/",

    $ curl -H "X-API-Key: yourkey" localhost:8384/rest/system/browse?current=/var/*o | json_pp
    [
        "/var/local/",
        "/var/lock/",
        "/var/log/",

        "/var/spool/"
    ]

  GET /rest/system/config (DEPRECATED)

Deprecated since version v1.12.0: This endpoint still works as before but is deprecated. Use /rest/config instead.

Returns the current configuration.

  GET /rest/system/config/insync (DEPRECATED)

Deprecated since version v1.12.0: This endpoint still works as before but is deprecated. Use /rest/config/restart-required 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)

Deprecated since version v1.12.0: This endpoint still works as before but is deprecated. Use Config Endpoints 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/restart-required 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 versions 0.13.0, 1.19.0 and 1.23.0.

Returns the list of configured devices and some metadata associated with them. The list also contains the local device itself as not connected.

The connection types are TCP (Client), TCP (Server), Relay (Client) and Relay (Server).

Added 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.

Added 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"
    }

  POST /rest/system/upgrade

Perform an upgrade to the newest released version and restart. Does nothing if there is no newer version than currently running.

  GET /rest/system/version

Returns the current Syncthing version information.

    {
      "arch": "amd64",
      "longVersion": "syncthing v0.10.27+3-gea8c3de (go1.4 darwin-amd64 default) jb@syno 2015-03-16 11:01:29 UTC",

      "version": "v0.10.27+3-gea8c3de"
    }

CONFIG ENDPOINTS

  Config Endpoints

Added 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, PATCH replaces only the given child objects and DELETE removes the folder/device.

  /rest/config/defaults/folder, /rest/config/defaults/device

GET returns a template folder / device configuration object with all default values, which only needs a unique ID to be applied. PUT replaces the default config (omitted values are reset to the hard-coded defaults), PATCH replaces only the given child objects.

  /rest/config/defaults/ignores

Added in version 1.19.0.

GET returns an object with a single lines attribute listing ignore patterns to be used by default on folders, as an array of single-line strings. PUT replaces the default ignore patterns from an object of the same format.

  /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.

NOTE: The gui.password configuration option has special handling to accept already hashed passwords. Any valid bcrypt hash is stored verbatim, while a plaintext password is first hashed.

CLUSTER ENDPOINTS

Concerns the mesh network structure.

  DELETE /rest/cluster/pending/devices

Added 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 GET /rest/cluster/pending/devices 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 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

Added in version 1.13.0.

Lists remote devices which have tried to connect, but are not yet configured in our instance.

    {
      "P56IOI7-MZJNU2Y-IQGDREY-DM2MGTI-MGL3BXN-PQ6W5BM-TBBZ4TJ-XZWICQ2": {
        "time": "2020-03-18T11:43:07Z",
        "name": "Friend Joe",
        "address": "192.168.1.2:22000"
      }
    }

  DELETE /rest/cluster/pending/folders

Added 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 GET /rest/cluster/pending/folders 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 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

Added 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.

    {
      "cpkn4-57ysy": {
        "offeredBy": {

      "perpage": 100
    }

  GET /rest/folder/pullerrors (DEPRECATED)

Deprecated since version v0.14.53: This endpoint still works as before but is deprecated. Use GET /rest/folder/errors instead, which returns the same information.

See https://github.com/syncthing/syncthing/commit/d510e3cca3d5caae42121fa206b3decc981ae59e

  GET /rest/folder/versions

Added in version 0.14.44.

Takes one mandatory parameter, folder, and returns the list of archived files that could be recovered. How many versions are available depends on the File Versioning configuration. Each entry specifies when the file version was archived as the versionTime, the modTime when it was last modified before being archived, and the size in bytes.

      ]
    }

  POST /rest/folder/versions

Restore archived versions of a given set of files. Expects an object with attributes named after the relative file paths, with timestamps as values matching valid versionTime entries in the corresponding GET /rest/folder/versions response object.

Takes the mandatory parameter folder (folder ID). Returns an object containing any error messages that occurred during restoration of the file, with the file path as attribute name.

    curl -X POST -H X-API-key:... http://127.0.0.1:8384/rest/folder/versions?folder=default -d '{

    }'

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.

    $ curl -s http://localhost:8384/rest/db/browse?folder=j663y-3ct3e&prefix=DCIM&levels=2

NOTE: This is an expensive call, increasing CPU and RAM usage on the device. Use sparingly.

  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:

    /rest/db/completion

  Example Response

    {
      "completion": 99.9937565835,
      "globalBytes": 156793013575,
      "needBytes": 9789241,
      "globalItems": 7823,
      "needItems": 412,
      "needDeletes": 0,
      "remoteState": "valid",
      "sequence": 12
    }

Added in version 1.8.0: The ability to aggregate multiple folders by leaving out the folder ID. Querying data for the local device by leaving out the device ID. Returning the globalItems counter in the response.

Added in version 1.20.0: Indication whether the remote device has accepted the folder (shares it with us) as well, and whether it is paused. The remoteState field is meaningless for aggregated responses, unknown when the remote device is not connected. Otherwise it can be either paused, notSharing, or valid if the remote is sharing back.

  GET /rest/db/file

Returns most data about a given file, including version and availability.

  Request

The call requires parameters for folder and file in the query string:

•   folder is the folder ID which you can find in the Syncthing Web GUI, e.g. 5camp-slpa8.

•   file is the relative path of the file starting from the folder root to the file you are interested in. The path and filename must be correctly URL-encoded.

  Example Request

    $ curl -s -H X-API-KEY:... "http://localhost:8384/rest/db/file?folder=YOUR_FOLDER_ID" --url-query "file=path/to/file.pdf"

  Response

    {
      "availability": [
        {
          "id": "ITZRNXE-YNROGBZ-HXTH5P7-VK5NYE5-QHRQGE2-7JQ6VNJ-KZUEDIU-5PPR5AM",
          "fromTemporary": false
        }
      ],
      "global": { /* a file entry */ },
      "local": { /* a file entry */ },
      "mtime": {
        "err": null,
        "value": {
          "real": "0001-01-01T00:00:00Z",
          "virtual": "0001-01-01T00:00:00Z"
      }
    }

local and global refer to the current file on the local device and the globally newest file, respectively. A file entry looks like this:

    {
      "deleted": false,
      "ignored": false,
      "inodeChange": "1970-01-01T01:00:00+01:00",
      "invalid": false,
      "localFlags": 0,
      "modified": "2022-09-28T08:07:19.979723+02:00",
      "modifiedBy": "523ITIE",
      "mustRescan": false,
      "name": "img",
      "noPermissions": false,
      "numBlocks": 0,
      "permissions": "0755",
      "platform": { /* platform specific data */ },
      "sequence": 914,
      "size": 128,

      "version": [
        "523ITIE:1664345275"
      ]
    }

Platform specific data may be ownership, extended attributes, etc. and is divided into entries per operating system / platform. An example platform entry containing ownership information for Unix systems and an extended attribute for macOS (“darwin”) looks as follows:

    {
      "darwin": {
        "xattrs": [
          {
            "name": "net.kastelo.xattrtest",
            "value": "aGVsbG8="
          }
        ]
      },
      "freebsd": null,
      "linux": null,
      "netbsd": null,
      "unix": {
        "gid": 20,
        "groupName": "staff",
        "ownerName": "jb",
        "uid": 501
      },
      "windows": null
    }

  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 /rest/db/ignores 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/localchanged

Added in version 0.14.55.

Takes one mandatory parameter, folder, and returns the list of files which were changed locally in a receive-only folder. Thus they differ from the global state and could be reverted by pulling from remote devices again, see POST /rest/db/revert.

The results can be paginated using the common pagination parameters.

    {
      "files": [
        {
          "flags": "0755",
          "sequence": 6,
          "modified": "2015-04-20T23:06:12+09:00",
          "name": "ls",
          "size": 34640,
          "version": [
            "5157751870738175669:1"
          ]
        }
      ],
      "page": 1,
      "perpage": 100
    }

NOTE: This is an expensive call, increasing CPU and RAM usage on the device. Use sparingly.

  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.

The results can be paginated using the common pagination parameters. 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.

    NOTE: Return format changed in version 0.14.43, removing the total count attribute.

        {
          # Files currently being downloaded
          "progress": [
            {
              "flags": "0755",

              "version": [
                "5157751870738175669:1"
              ]
            }
          ],
          # Files queued to be downloaded next (as per array order)
          "queued": [
              ...
          ],
          # Files to be downloaded after all queued files will be downloaded.
          # This happens when we start downloading files, and new files get added while we are downloading.
          "rest": [
              ...
          ],
          "page": 1,
          "perpage": 100
        }

    NOTE: This is an expensive call, increasing CPU and RAM usage on the device. Use sparingly.

  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.

  GET /rest/db/remoteneed

Added in version 0.14.43.

Takes the mandatory parameters folder and device, and returns the list of files which are needed by that remote device in order for it to become in sync with the shared folder.

The results can be paginated using the common pagination parameters.

    {
      "files": [
        {
          "flags": "0755",
          "sequence": 6,

          ]
        }
      ],
      "page": 1,
      "perpage": 100
    }

NOTE: This is an expensive call, increasing CPU and RAM usage on the device. Use sparingly.

  POST /rest/db/revert

Added 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. If no filter is specified, all events except LocalChangeDetected and RemoteChangeDetected are included.

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. If <lastSeenID> is a future ID, the HTTP call blocks until such ID is reached or timeouts. 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.

  GET /rest/events/disk

This convenience endpoint provides the same event stream, but pre-filtered to show only LocalChangeDetected and RemoteChangeDetected event types. The events parameter is not used.

STATISTICS ENDPOINTS

  GET /rest/stats/device
