title: Matrix Client-Server sync API
version: 1.0.0
paths:
/sync:
get:
summary: Synchronise the client's state and receive new messages.
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.
operationId: sync
security:
- accessTokenQuery: []
- accessTokenBearer: []
parameters:
- in: query
name: filter
description: |-
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.
See [Filtering](/client-server-api/#filtering) for more information.
example: 66696p746572
schema:
type: string
- in: query
name: since
description: |-
A point in time to continue a sync from. This should be the
`next_batch` token returned by an earlier call to this endpoint.
example: s72594_4483_1934
schema:
type: string
- in: query
name: full_state
description: |-
Controls whether to include the full state for all rooms the user
is a member of.
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.
By default, this is `false`.
example: false
schema:
type: boolean
- in: query
name: set_presence
description: |-
Controls whether the client is automatically marked as online by
polling this API. If this parameter is omitted then the client is
automatically marked as online when it uses this API. Otherwise if
the parameter is set to "offline" then the client is not marked as
being online when it uses this API. When set to "unavailable", the
client is marked as being idle.
example: offline
schema:
type: string
enum:
- offline
- online
- unavailable
- in: query
name: timeout
description: |-
The maximum time to wait, in milliseconds, before returning this
request. If no events (or other data) become available before this
time elapses, the server will return a response with empty fields.
By default, this is `0`, so the server will return immediately
even if the response is empty.

summary:
title: RoomSummary
type: object
description: |-
Information about the room which clients may need to
correctly render it to users.
properties:
m.heroes:
type: array
description: |-
The users which can be used to generate a room name
if the room does not have one. Required if the room's
`m.room.name` or `m.room.canonical_alias` state events
are unset or empty.
This should be the first 5 members of the room, ordered
by stream ordering, which are joined or invited. The
list must never include the client's own user ID. When
no joined or invited members are available, this should
consist of the banned and left users. More than 5 members
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
events for the heroes MUST be included in the `state`,
unless they are redundant. When the list of users changes,
the server notifies the client by sending a fresh list of
heroes. If there are no changes since the last sync, this
field may be omitted.
items:
type: string
m.joined_member_count:
type: integer
description: |-
The number of users with `membership` of `join`,

Required otherwise.

description: |-
The number of users with `membership` of `invite`.
If this field has not changed since the last sync, it
may be omitted. Required otherwise.
state:

Updates to the state, between the time indicated by
the `since` parameter, and the start of the
`timeline` (or all state up to the start of the
`timeline`, if `since` is not given, or
`full_state` is true).
N.B. state updates for `m.room.member` events will
be incomplete if `lazy_load_members` is enabled in
the `/sync` filter, and only return the member events
required to display the senders of the timeline events
in this response.
