**Note:**
|
|
This API is nearly identical to the v1 API with the
|
|
exception of the response format being fixed.
|
|
|
|
This endpoint is preferred over the v1 API as it provides
|
|
a more standarised response format. Senders which receive
|
|
a 400, 404, or other status code which indicates this endpoint
|
|
is not available should retry using the v1 API instead.
|
|
|
|
Submits a signed join event to the resident server for it
|
|
to accept it into the room's graph. Note that events have
|
|
a different format depending on the room version - check
|
|
the [room version specification](/rooms) for precise event formats.
|

**The request and response body here describe the common
|
|
event fields in more detail and may be missing other required

[Client-Server /sync

server should include these members' membership events in the

response `state` field, and include the auth chains for these
|
|
membership events in the response `auth_chain` field.

An arbitrary user ID belonging to the resident server in

The request is invalid in some way.

The error should be passed through to clients so that they

may give better feedback to users.
|
|
|
|
New in `v1.2`, the following error conditions might happen:
|
|
|
|
If the room is [restricted](/client-server-api/#restricted-rooms)
|
|
and none of the conditions can be validated by the server then
|
|
the `errcode` `M_UNABLE_TO_AUTHORISE_JOIN` must be used. This can
|
|
happen if the server does not know about any of the rooms listed
|
|
as conditions, for example.
|
|
|
|
`M_UNABLE_TO_GRANT_JOIN` is returned to denote that a different
|
|
server should be attempted for the join. This is typically because
|
|
the resident server can see that the joining user satisfies one or
|
|
more conditions, such as in the case of
|
|
[restricted rooms](/client-server-api/#restricted-rooms), but the
|
|
resident server would be unable to meet the auth rules governing
|
|
`join_authorised_via_users_server` on the resulting `m.room.member`
|
|
event.
