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/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.

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/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.

Request override of a send-only 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 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.

EVENT ENDPOINTS
Event API
Description
Syncthing provides a simple long polling interface for exposing events from the core utility towards a
GUI.
To receive events, perform a HTTP GET of /rest/events or /rest/events/disk. The latter returns only
local-change-detected and remote-change-detected events, the former all other events unless filtered.
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 from the list below.
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.
Event Structure
Each event is represented by an object similar to the following:
{
"id": 2,
"globalID": 3,
"type": "DeviceConnected",
"time": "2014-07-13T21:04:33.687836696+02:00",
"data": {
"addr": "172.16.32.25:22000",
"id": "NFGKEKE-7Z6RTH7-I3PRZXS-DEJF3UJ-FRWJBFO-VBBTDND-4SGNGVZ-QUQHJAG"
}
}
The top level keys id, globalID, time, type and data are always present, though data may be null.
id A unique ID for this event on the events API. It always increases by 1: the first event generated
has id 1, the next has id 2 etc. If this increases by more than 1, then one or more events have
been skipped by the events API.
globalID
A global ID for this event, across the events API, the audit log, and any other sources. It may
increase by more than 1, but it will always be greater than or equal to the id.
time The time the event was generated.
type Indicates the type of (i.e. reason for) the event and is one of the event types below.
data An object containing optional extra information; the exact structure is determined by the event
type.
Event Types
ConfigSaved
Emitted after the config has been saved by the user or by Syncthing itself.
{
"id": 50,
"type": "ConfigSaved",

Generated each time a connection to a device has been established.
{
"id": 2,
"type": "DeviceConnected",
"time": "2014-07-13T21:04:33.687836696+02:00",
"data": {

"clientName": "syncthing",
"clientVersion": "v0.13.4",
"type": "TCP (Client)"
}
}
DeviceDisconnected
Generated each time a connection to a device has been terminated.

• Total - total number of blocks in the file
• Pulling - number of blocks currently being downloaded
• CopiedFromOrigin - number of blocks copied from the file we are about to replace
• Reused - number of blocks reused from a previous temporary file
• CopiedFromElsewhere - number of blocks copied from other files or potentially other folders
• Pulled - number of blocks actually downloaded so far
• BytesTotal - approximate total file size
• BytesDone - approximate number of bytes already handled (already reused, copied or pulled)
Where block size is 128KB.
Files/folders appearing in the event data imply that the download has been started for that file/folder,
where disappearing implies that the downloads have been finished or failed for that file/folder. There is
always a last event emitted with no data, which implies all downloads have finished/failed.
FolderCompletion
The FolderCompletion event is emitted when the local or remote contents for a folder changes. It contains
the completion percentage for a given remote device and is emitted once per currently connected remote
device.

"folder": "default"
}
}
FolderErrors
The FolderErrors event is emitted when a folder cannot be successfully synchronized. The event contains
the ID of the affected folder and a list of errors for files or directories therein. This list of errors
is obsolete once the folder changes state to syncing - if errors remain after the next synchronization
attempt, a new FolderErrors event is emitted.
{
"id": 132,
"type": "FolderErrors",
"time": "2015-06-26T13:39:24.697401384+02:00",

}
],
"folder": "default"
}
}
New in version 0.11.12.
