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 to 0.
  • limit - Maximum amount of rooms to return. Defaults to 100.
  • order_by - The method in which to sort the returned list of rooms. Valid values are:
    • alphabetical - Same as name. This is deprecated.
    • size - Same as joined_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. Either f for forwards or b for backwards. Setting this value to b will reverse the above sort order. Defaults to f.
  • 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 - The user_id of the room creator.
      • encryption - Algorithm of end-to-end encryption of messages. Is null 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.
  • offset - The current pagination offset in rooms. This parameter should be used instead of next_token for room offset as next_token is not intended to be parsed.
  • total_rooms - The total number of rooms this query can return. Using this and offset, 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 use next_batch to get the "next page" of results. To do so, simply repeat your request, setting the from parameter to the value of next_batch.
  • prev_batch - If this field is present, it is possible to paginate backwards. Use prev_batch for the from value in the next request to get the "previous page" of results.

{}

Response:

{
  "rooms": [

      "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",
      "name": "Music Theory",
      "canonical_alias": "#musictheory:matrix.org",
      "joined_members": 127
      "joined_local_members": 2,
      "version": "1",
      "creator": "@foo:matrix.org",
      "encryption": null,
      "federatable": true,
      "public": true,
      "join_rules": "invite",
      "guest_access": null,
      "history_visibility": "shared",
      "state_events": 93534
    },
    ... (48 hidden items) ...
    {
      "room_id": "!twcBhHVdZlQWuuxBhN:termina.org.uk",
      "name": "weechat-matrix",
      "canonical_alias": "#weechat-matrix:termina.org.uk",
      "joined_members": 137
      "joined_local_members": 20,
      "version": "4",
      "creator": "@foo:termina.org.uk",
      "encryption": null,
      "federatable": true,
      "public": true,
      "join_rules": "invite",
      "guest_access": null,
      "history_visibility": "shared",
      "state_events": 8345
    }
  ],
  "offset": 100,
  "prev_batch": 0,
  "total_rooms": 150
}

Once the next_token parameter is no longer present, we know we've reached the end of the list.

}

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:

{

    "@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. It is a combination and improvement of "Shutdown room" and "Purge room" API.

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 to Content Violation Notification
  • message - Optional. A string containing the first message that will be sent as new_room_user_id in the new room. Ideally this will clearly convey why the original room was shut down. Defaults to Sharing illegal content on this server is not permitted and rooms in violation will be blocked.
  • block - Optional. If set to true, this room will be added to a blocking list, preventing future attempts to join the room. Defaults to false.
  • purge - Optional. If set to true, it will remove all traces of the room from your database. Defaults to true.

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.
