.SH DESCRIPTION
.sp
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.
.SH API KEY
.sp
To use the POST methods, or \fIany\fP 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
\fBconfiguration/gui/apikey\fP element in the configuration file. To use an API
key, set the request header \fBX\-API\-Key\fP to the API key value. For example,
\fBcurl \-X POST \-H "X\-API\-Key: abc123" http://localhost:8384/rest/...\fP can be
used to invoke authenticated POST methods via \fBcurl\fP\&.

.SS POST /rest/db/scan
.sp
Request immediate rescan of a folder, or a specific path within a folder.
Takes the mandatory parameter \fIfolder\fP (folder ID), an optional parameter
\fBsub\fP (path relative to the folder root) and an optional parameter \fBnext\fP\&. If
\fBsub\fP is omitted or empty, the entire folder is scanned for changes, otherwise
only the given path (and children, in case it\(aqs a directory) is scanned. The
\fBnext\fP argument delays Syncthing\(aqs automated rescan interval for a given
amount of seconds.
.sp
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
