SYNCTHING-REST-API(7) Syncthing SYNCTHING-REST-API(7)

NAME

syncthing-rest-api - REST API

DESCRIPTION

Syncthing exposes a REST interface over HTTP on the GUI port. This is used by the GUI code (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 AP 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.

SYSTEM ENDPOINTS

GET /rest/system/config

Returns the current configuration.

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=default | json_pp

   "directory": {
      "file": ["2015-04-20T22:20:45+09:00", 130940928],

   "subdirectory": {}
}


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) for a given device and folder. Takes device and folder parameters. 

{
  "completion": 0
}


NOTE:

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


GET /rest/db/file

Returns most data available about a given file, including version and availability. Takes folder and file parameters. 

{
  "availability": [
    "I6KAH76-66SLLLB-5PFXSOA-UFJCDZC-YAOMLEK-CP2GB32-BV5RQST-3PSROAU"

      "5407294127585413568:1"
    ]
  }
}


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.

NOTE:

curl -X POST 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/scan

Request immediate rescan of a folder, or a specific path within a folder. Takes the mandatory parameter folder (folder ID), an optional parameter sub (path relative to the folder root) and an optional parameter next. If sub is omitted or empty, the entire folder is scanned for changes, otherwise only the given 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.
