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 POST methods, or any method when authentication is enabled, 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 authenticated POST methods via curl.
SYSTEM ENDPOINTS

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.

"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.

}
}
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 (patterns 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 master folder. Takes the mandatory parameter
folder (folder ID).
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.
