.SH ANNOUNCEMENTS
|
|
.sp
|
|
A device should announce itself at startup. It does this by an HTTPS POST to
|
|
the announce server URL. Standard discovery currently requires the path to be
|
|
"/v2/", yet this can be up to the discovery server. The POST has a JSON payload
|
|
listing connection addresses (if any):
|
|
.INDENT 0.0
|
|
.INDENT 3.5
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
{
|
|
addresses: ["tcp://192.0.2.45:22000", "tcp://:22202", "relay://192.0.2.99:22028"],
|
|
}
|
|
.ft P
|
|
.fi

|
.UNINDENT

|
.UNINDENT
|
|
.sp
|
|
It\(aqs OK for the "addresses" field to be either the empty list (\fB[]\fP),
|
|
\fBnull\fP, or missing entirely. An announcement with the field missing
|
|
or empty is however not useful...
|
|
.sp
|
|
Any empty or unspecified IP addresses (i.e. addresses like \fBtcp://:22000\fP,
|
|
\fBtcp://0.0.0.0:22000\fP, \fBtcp://[::]:22000\fP) are interpreted as referring to
|
|
the source IP address of the announcement.
|
|
.sp
|
|
The device ID of the announcing device is not part of the announcement.
|
|
Instead, the server requires that the client perform certificate
|
|
authentication. The device ID is deduced from the presented certificate.
|
|
.sp
|
|
The server response is empty, with code \fB204\fP (No Content) on success. If no
|
|
certificate was presented, status \fB403\fP (Forbidden) is returned. If the
|
|
posted data doesn\(aqt conform to the expected format, \fB400\fP (Bad Request) is
|
|
returned.
|
|
.sp
|
|
In successful responses, the server may return a \fBReannounce\-After\fP header
|
|
containing the number of seconds after which the client should perform a new
|
|
announcement.
|
|
.sp
|
|
In error responses, the server may return a \fBRetry\-After\fP header containing
|
|
the number of seconds after which the client should retry.
|
|
.sp
|
|
Performing announcements significantly more often than indicated by the
|
|
\fBReannounce\-After\fP or \fBRetry\-After\fP headers may result in the client being
|
|
throttled. In such cases the server may respond with status code \fB429\fP (Too
|
|
Many Requests).
|
|
.SH QUERIES
|
|
.sp
|
|
Queries are performed as HTTPS GET requests to the announce server URL. The
|
|
requested device ID is passed as the query parameter "device", in canonical
|
|
string form, i.e. \fBhttps://announce.syncthing.net/v2/?device=ABC12345\-....\fP
|
|
.sp
|
|
Successful responses will have status code \fB200\fP (OK) and carry a JSON payload
|
|
of the same format as the announcement above. The response will not contain
|
|
empty or unspecified addresses.
|
|
.sp
|
|
If the "device" query parameter is missing or malformed, the status code 400
|
|
(Bad Request) is returned.
|
|
.sp
|
|
If the device ID is of a valid format but not found in the registry, 404 (Not
|
|
Found) is returned.
|
|
.sp
|
|
If the client has exceeded a rate limit, the server may respond with 429 (Too
|
|
Many Requests).
