List Room API
The List Room admin API allows server admins to get a list of rooms on their server. There are various parameters available that allow for filtering and sorting the returned list. This API supports pagination.
Parameters
The following query parameters are available:
from
- Offset in the returned list. Defaults to0
.limit
- Maximum amount of rooms to return. Defaults to100
.order_by
- The method in which to sort the returned list of rooms. Valid values are:alphabetical
- Same asname
. This is deprecated.size
- Same asjoined_members
. This is deprecated.name
- Rooms are ordered alphabetically by room name. This is the default.canonical_alias
- Rooms are ordered alphabetically by main alias address of the room.joined_members
- Rooms are ordered by the number of members. Largest to smallest.joined_local_members
- Rooms are ordered by the number of local members. Largest to smallest.version
- Rooms are ordered by room version. Largest to smallest.creator
- Rooms are ordered alphabetically by creator of the room.encryption
- Rooms are ordered alphabetically by the end-to-end encryption algorithm.federatable
- Rooms are ordered by whether the room is federatable.public
- Rooms are ordered by visibility in room list.join_rules
- Rooms are ordered alphabetically by join rules of the room.guest_access
- Rooms are ordered alphabetically by guest access option of the room.history_visibility
- Rooms are ordered alphabetically by visibility of history of the room.state_events
- Rooms are ordered by number of state events. Largest to smallest.
dir
- Direction of room order. Eitherf
for forwards orb
for backwards. Setting this value tob
will reverse the above sort order. Defaults tof
.search_term
- Filter rooms by their room name. Search term can be contained in any part of the room name. Defaults to no filtering.
The following fields are possible in the JSON response body:
rooms
- An array of objects, each containing information about a room.- Room objects contain the following fields:
room_id
- The ID of the room.name
- The name of the room.canonical_alias
- The canonical (main) alias address of the room.joined_members
- How many users are currently in the room.joined_local_members
- How many local users are currently in the room.version
- The version of the room as a string.creator
- Theuser_id
of the room creator.encryption
- Algorithm of end-to-end encryption of messages. Isnull
if encryption is not active.federatable
- Whether users on other servers can join this room.public
- Whether the room is visible in room directory.join_rules
- The type of rules used for users wishing to join this room. One of: ["public", "knock", "invite", "private"].guest_access
- Whether guests can join the room. One of: ["can_join", "forbidden"].history_visibility
- Who can see the room history. One of: ["invited", "joined", "shared", "world_readable"].state_events
- Total number of state_events of a room. Complexity of the room.
- Room objects contain the following fields:
offset
- The current pagination offset in rooms. This parameter should be used instead ofnext_token
for room offset asnext_token
is not intended to be parsed.total_rooms
- The total number of rooms this query can return. Using this andoffset
, you have enough information to know the current progression through the list.next_batch
- If this field is present, we know that there are potentially more rooms on the server that did not all fit into this response. We can usenext_batch
to get the "next page" of results. To do so, simply repeat your request, setting thefrom
parameter to the value ofnext_batch
.prev_batch
- If this field is present, it is possible to paginate backwards. Useprev_batch
for thefrom
value in the next request to get the "previous page" of results.
Usage

}
Paginating through a list of rooms:
GET /_synapse/admin/v1/rooms?order_by=size
{}
Response:
{
"rooms": [
{
"room_id": "!OGEhHVWSdvArJzumhm:matrix.org",

"state_events": 8345
}
],
"offset": 0,
"total_rooms": 150
"next_token": 100
}
The presence of the next_token
parameter tells us that there are more rooms
than returned in this request, and we need to make another request to get them.
To get the next batch of room results, we repeat our request, setting the from
parameter to the value of next_token
.
GET /_synapse/admin/v1/rooms?order_by=size&from=100
{}
Response:
{
"rooms": [
{
"room_id": "!mscvqgqpHYjBGDxNym:matrix.org",

}
],
"offset": 100,

Room Members API
The Room Members admin API allows server admins to get a list of all members of a room.
The response includes the following fields:
members
- A list of all the members that are present in the room, represented by their ids.total
- Total number of members in the room.
Usage
A standard request:
GET /_synapse/admin/v1/rooms/<room_id>/members
{}
Response:
{
"members": [
"@foo:matrix.org",
"@bar:matrix.org",
"@foobar:matrix.org"
],
"total": 3
}
Delete Room API
The Delete Room admin API allows server admins to remove rooms from server and block these rooms.
Shuts down a room. Moves all local users and room aliases automatically to a
new room if new_room_user_id
is set. Otherwise local users only
leave the room without any information.
The new room will be created with the user specified by the new_room_user_id
parameter
as room administrator and will contain a message explaining what happened. Users invited
to the new room will have power level -10
by default, and thus be unable to speak.
If block
is True
it prevents new joins to the old room.
This API will remove all trace of the old room from your database after removing
all local users. If purge
is true
(the default), all traces of the old room will
be removed from your database after removing all local users. If you do not want
this to happen, set purge
to false
.
Depending on the amount of history being purged a call to the API may take
several minutes or longer.
The local server will only have the power to move local user and room aliases to the new room. Users on other servers will be unaffected.
The API is:
POST /_synapse/admin/v1/rooms/<room_id>/delete
with a body of:
{
"new_room_user_id": "@someuser:example.com",
"room_name": "Content Violation Notification",
"message": "Bad Room has been shutdown due to content violations on this server. Please review our Terms of Service.",
"block": true,
"purge": true
}
To use it, you will need to authenticate by providing an access_token
for a
server admin: see README.rst.
A response body like the following is returned:
{
"kicked_users": [
"@foobar:example.com"
],
"failed_to_kick_users": [],
"local_aliases": [
"#badroom:example.com",
"#evilsaloon:example.com"
],
"new_room_id": "!newroomid:example.com"
}
Parameters
The following parameters should be set in the URL:
room_id
- The ID of the room.
The following JSON body parameters are available:
new_room_user_id
- Optional. If set, a new room will be created with this user ID as the creator and admin, and all users in the old room will be moved into that room. If not set, no new room will be created and the users will just be removed from the old room. The user ID must be on the local server, but does not necessarily have to belong to a registered user.room_name
- Optional. A string representing the name of the room that new users will be invited to. Defaults toContent Violation Notification
message
- Optional. A string containing the first message that will be sent asnew_room_user_id
in the new room. Ideally this will clearly convey why the original room was shut down. Defaults toSharing illegal content on this server is not permitted and rooms in violation will be blocked.
block
- Optional. If set totrue
, this room will be added to a blocking list, preventing future attempts to join the room. Defaults tofalse
.purge
- Optional. If set totrue
, it will remove all traces of the room from your database. Defaults totrue
.force_purge
- Optional, and ignored unlesspurge
istrue
. If set totrue
, it will force a purge to go ahead even if there are local users still in the room. Do not use this unless a regularpurge
operation fails, as it could leave those users' clients in a confused state.
The JSON body must not be empty. The body must be at least {}
.
Response
The following fields are returned in the JSON response body:
kicked_users
- An array of users (user_id
) that were kicked.failed_to_kick_users
- An array of users (user_id
) that that were not kicked.local_aliases
- An array of strings representing the local aliases that were migrated from the old room to the new.new_room_id
- A string representing the room ID of the new room.
Undoing room shutdowns
Note: This guide may be outdated by the time you read it. By nature of room shutdowns being performed at the database level, the structure can and does change without notice.
First, it's important to understand that a room shutdown is very destructive. Undoing a shutdown is not as simple as pretending it never happened - work has to be done to move forward instead of resetting the past. In fact, in some cases it might not be possible to recover at all:
- If the room was invite-only, your users will need to be re-invited.
- If the room no longer has any members at all, it'll be impossible to rejoin.
- The first user to rejoin will have to do so via an alias on a different server.
With all that being said, if you still want to try and recover the room:
- For safety reasons, shut down Synapse.
- In the database, run
DELETE FROM blocked_rooms WHERE room_id = '!example:example.org';
- For caution: it's recommended to run this in a transaction:
BEGIN; DELETE ...;
, verify you got 1 result, thenCOMMIT;
. - The room ID is the same one supplied to the shutdown room API, not the Content Violation room.
- For caution: it's recommended to run this in a transaction:
- Restart Synapse.
You will have to manually handle, if you so choose, the following:
- Aliases that would have been redirected to the Content Violation room.
- Users that would have been booted from the room (and will have been force-joined to the Content Violation room).
- Removal of the Content Violation room if desired.
Make Room Admin API
Grants another user the highest power available to a local user who is in the room. If the user is not in the room, and it is not publicly joinable, then invite the user.
By default the server admin (the caller) is granted power, but another user can optionally be specified, e.g.:
POST /_synapse/admin/v1/rooms/<room_id_or_alias>/make_room_admin
{
"user_id": "@foo:example.com"
}
Forward Extremities Admin API
Enables querying and deleting forward extremities from rooms. When a lot of forward extremities accumulate in a room, performance can become degraded.
When using this API endpoint to delete any extra forward extremities for a room, the server does not need to be restarted as the relevant caches will be cleared in the API call.
Check for forward extremities
To check the status of forward extremities for a room:
GET /_synapse/admin/v1/rooms/<room_id_or_alias>/forward_extremities
A response as follows will be returned:
{
"count": 1,
"results": [
{
"event_id": "$M5SP266vsnxctfwFgFLNceaCo3ujhRtg_NiiHabcdfgh",
"state_group": 439
}
]
}
Deleting forward extremities
If a room has lots of forward extremities, the extra can be deleted as follows:
DELETE /_synapse/admin/v1/rooms/<room_id_or_alias>/forward_extremities
A response as follows will be returned, indicating the amount of forward extremities that were deleted.
{
"deleted": 1
}
The cache get_latest_event_ids_in_room
will be invalidated, if any forward extremities
were deleted.
