|
|
|
description: |-
|
|
|
|
|
Synchronise the client's state with the latest state on the server.
|
|
|
|
|
Clients use this API when they first log in to get an initial snapshot
|
|
|
|
|
of the state on the server, and then continue to call this API to get
|
|
|
|
|
incremental deltas to the state, and to receive new messages.
|
|
|
|
|
|
|
|
|
|
*Note*: This endpoint supports lazy-loading. See [Filtering](/client-server-api/#filtering)
|
|
|
|
|
for more information. Lazy-loading members is only supported on a `StateFilter`
|
|
|
|
|
for this endpoint. When lazy-loading is enabled, servers MUST include the
|
|
|
|
|
syncing user's own membership event when they join a room, or when the
|
|
|
|
|
full state of rooms is requested, to aid discovering the user's avatar &
|
|
|
|
|
displayname.
|
|
|
|
|
|
|
|
|
|
Further, like other members, the user's own membership event is eligible
|
|
|
|
|
for being considered redundant by the server. When a sync is `limited`,
|
|
|
|
|
the server MUST return membership events for events in the gap
|
|
|
|
|
(between `since` and the start of the returned timeline), regardless
|
|
|
|
|
as to whether or not they are redundant. This ensures that joins/leaves
|
|
|
|
|
and profile changes which occur during the gap are not lost.
|
|
|
|
|
|
|
|
|
|
Note that the default behaviour of `state` is to include all membership
|
|
|
|
|
events, alongside other state, when lazy-loading is not enabled.

The ID of a filter created using the filter API or a filter JSON

object encoded as a string. The server will detect whether it is
|
|
|
|
|
an ID or a JSON object by whether the first character is a `"{"`
|
|
|
|
|
open brace. Passing the JSON inline is best suited to one off
|
|
|
|
|
requests. Creating a filter using the filter API is recommended for
|
|
|
|
|
clients that reuse the same filter multiple times, for example in
|
|
|
|
|
long poll requests.

If this is set to `true`, then all state events will be returned,
|
|
|
|
|
even if `since` is non-empty. The timeline will still be limited
|
|
|
|
|
by the `since` parameter. In this case, the `timeout` parameter
|
|
|
|
|
will be ignored and the query will return immediately, possibly with
|
|
|
|
|
an empty timeline.
|
|
|
|
|
|
|
|
|
|
If `false`, and `since` is non-empty, only state which has
|
|
|
|
|
changed since the point indicated by `since` will be returned.
|
|
|
|
|

This should be the first 5 members of the room, ordered

no joined or invited members are available, this should

may be provided, however less than 5 should only be provided

when there are less than 5 members to represent.

When lazy-loading room members is enabled, the membership
