<h1 id="list-room-api"><a class="header" href="#list-room-api">List Room API</a></h1>
<p>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.</p>
<p>To use it, you will need to authenticate by providing an <code>access_token</code>
for a server admin: see <a href="../usage/administration/admin_api">Admin API</a>.</p>
<p><strong>Parameters</strong></p>
<p>The following query parameters are available:</p>
<ul>
<li>
<p><code>from</code> - Offset in the returned list. Defaults to <code>0</code>.</p>
</li>
<li>
<p><code>limit</code> - Maximum amount of rooms to return. Defaults to <code>100</code>.</p>
</li>
<li>
<p><code>order_by</code> - The method in which to sort the returned list of rooms. Valid values are:</p>
<ul>
<li><code>alphabetical</code> - Same as <code>name</code>. This is deprecated.</li>
<li><code>size</code> - Same as <code>joined_members</code>. This is deprecated.</li>
<li><code>name</code> - Rooms are ordered alphabetically by room name. This is the default.</li>
<li><code>canonical_alias</code> - Rooms are ordered alphabetically by main alias address of the room.</li>
<li><code>joined_members</code> - Rooms are ordered by the number of members. Largest to smallest.</li>
<li><code>joined_local_members</code> - Rooms are ordered by the number of local members. Largest to smallest.</li>
<li><code>version</code> - Rooms are ordered by room version. Largest to smallest.</li>
<li><code>creator</code> - Rooms are ordered alphabetically by creator of the room.</li>
<li><code>encryption</code> - Rooms are ordered alphabetically by the end-to-end encryption algorithm.</li>
<li><code>federatable</code> - Rooms are ordered by whether the room is federatable.</li>
<li><code>public</code> - Rooms are ordered by visibility in room list.</li>
<li><code>join_rules</code> - Rooms are ordered alphabetically by join rules of the room.</li>
<li><code>guest_access</code> - Rooms are ordered alphabetically by guest access option of the room.</li>
<li><code>history_visibility</code> - Rooms are ordered alphabetically by visibility of history of the room.</li>
<li><code>state_events</code> - Rooms are ordered by number of state events. Largest to smallest.</li>
</ul>
</li>
<li>
<p><code>dir</code> - Direction of room order. Either <code>f</code> for forwards or <code>b</code> for backwards. Setting
this value to <code>b</code> will reverse the above sort order. Defaults to <code>f</code>.</p>
</li>
<li>
<p><code>search_term</code> - Filter rooms by their room name, canonical alias and room id.
Specifically, rooms are selected if the search term is contained in</p>
<ul>
<li>the room's name,</li>
<li>the local part of the room's canonical alias, or</li>
<li>the complete (local and server part) room's id (case sensitive).</li>
</ul>
<p>Defaults to no filtering.</p>
</li>
</ul>
<p><strong>Response</strong></p>
<p>The following fields are possible in the JSON response body:</p>
<ul>
<li><code>rooms</code> - An array of objects, each containing information about a room.
<ul>
<li>Room objects contain the following fields:
<ul>
<li><code>room_id</code> - The ID of the room.</li>
<li><code>name</code> - The name of the room.</li>
<li><code>canonical_alias</code> - The canonical (main) alias address of the room.</li>
<li><code>joined_members</code> - How many users are currently in the room.</li>
<li><code>joined_local_members</code> - How many local users are currently in the room.</li>
<li><code>version</code> - The version of the room as a string.</li>
<li><code>creator</code> - The <code>user_id</code> of the room creator.</li>
<li><code>encryption</code> - Algorithm of end-to-end encryption of messages. Is <code>null</code> if encryption is not active.</li>
<li><code>federatable</code> - Whether users on other servers can join this room.</li>
<li><code>public</code> - Whether the room is visible in room directory.</li>
<li><code>join_rules</code> - The type of rules used for users wishing to join this room. One of: ["public", "knock", "invite", "private"].</li>
<li><code>guest_access</code> - Whether guests can join the room. One of: ["can_join", "forbidden"].</li>
<li><code>history_visibility</code> - Who can see the room history. One of: ["invited", "joined", "shared", "world_readable"].</li>
<li><code>state_events</code> - Total number of state_events of a room. Complexity of the room.</li>
</ul>
</li>
</ul>
</li>
<li><code>offset</code> - The current pagination offset in rooms. This parameter should be
used instead of <code>next_token</code> for room offset as <code>next_token</code> is
not intended to be parsed.</li>
<li><code>total_rooms</code> - The total number of rooms this query can return. Using this
and <code>offset</code>, you have enough information to know the current
progression through the list.</li>
<li><code>next_batch</code> - 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 <code>next_batch</code> to get the "next page" of results. To do
so, simply repeat your request, setting the <code>from</code> parameter to
the value of <code>next_batch</code>.</li>
<li><code>prev_batch</code> - If this field is present, it is possible to paginate backwards.
Use <code>prev_batch</code> for the <code>from</code> value in the next request to
get the "previous page" of results.</li>
</ul>

<h1 id="delete-room-api"><a class="header" href="#delete-room-api">Delete Room API</a></h1>
<p>The Delete Room admin API allows server admins to remove rooms from the server
and block these rooms.</p>
<p>Shuts down a room. Moves all local users and room aliases automatically to a
new room if <code>new_room_user_id</code> is set. Otherwise local users only
leave the room without any information.</p>
<p>The new room will be created with the user specified by the <code>new_room_user_id</code> parameter
as room administrator and will contain a message explaining what happened. Users invited
to the new room will have power level <code>-10</code> by default, and thus be unable to speak.</p>
<p>If <code>block</code> is <code>true</code>, users will be prevented from joining the old room.
This option can in <a href="#version-1-old-version">Version 1</a> also be used to pre-emptively
block a room, even if it's unknown to this homeserver. In this case, the room will be
blocked, and no further action will be taken. If <code>block</code> is <code>false</code>, attempting to
delete an unknown room is invalid and will be rejected as a bad request.</p>
<p>This API will remove all trace of the old room from your database after removing
all local users. If <code>purge</code> is <code>true</code> (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 <code>purge</code> to <code>false</code>.
Depending on the amount of history being purged, a call to the API may take
several minutes or longer.</p>
<p>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.</p>
<h2 id="version-1-old-version"><a class="header" href="#version-1-old-version">Version 1 (old version)</a></h2>
<p>This version works synchronously. That means you only get the response once the server has
finished the action, which may take a long time. If you request the same action
a second time, and the server has not finished the first one, the second request will block.
This is fixed in version 2 of this API. The parameters are the same in both APIs.
This API will become deprecated in the future.</p>
<p>The API is:</p>
<pre><code>DELETE /_synapse/admin/v1/rooms/<room_id>
</code></pre>
<p>with a body of:</p>
<pre><code class="language-json">{
"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
}
</code></pre>
<p>A response body like the following is returned:</p>
<pre><code class="language-json">{
"kicked_users": [
"@foobar:example.com"
],
"failed_to_kick_users": [],
"local_aliases": [
"#badroom:example.com",
"#evilsaloon:example.com"
],
"new_room_id": "!newroomid:example.com"
}
</code></pre>
<p>The parameters and response values have the same format as
<a href="#version-2-new-version">version 2</a> of the API.</p>
<h2 id="version-2-new-version"><a class="header" href="#version-2-new-version">Version 2 (new version)</a></h2>
<p><strong>Note</strong>: This API is new, experimental and "subject to change".</p>
<p>This version works asynchronously, meaning you get the response from server immediately
while the server works on that task in background. You can then request the status of the action
to check if it has completed.</p>
<p>The API is:</p>
<pre><code>DELETE /_synapse/admin/v2/rooms/<room_id>
</code></pre>
<p>with a body of:</p>
<pre><code class="language-json">{
"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
}
</code></pre>
<p>The API starts the shut down and purge running, and returns immediately with a JSON body with
a purge id:</p>
<pre><code class="language-json">{
"delete_id": "<opaque id>"
}
</code></pre>
<p><strong>Parameters</strong></p>
<p>The following parameters should be set in the URL:</p>
<ul>
<li><code>room_id</code> - The ID of the room.</li>
</ul>
<p>The following JSON body parameters are available:</p>
<ul>
<li><code>new_room_user_id</code> - 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.</li>
<li><code>room_name</code> - Optional. A string representing the name of the room that new users will be
invited to. Defaults to <code>Content Violation Notification</code></li>
<li><code>message</code> - Optional. A string containing the first message that will be sent as
<code>new_room_user_id</code> in the new room. Ideally this will clearly convey why the
original room was shut down. Defaults to <code>Sharing illegal content on this server is not permitted and rooms in violation will be blocked.</code></li>
<li><code>block</code> - Optional. If set to <code>true</code>, this room will be added to a blocking list,
preventing future attempts to join the room. Rooms can be blocked
even if they're not yet known to the homeserver (only with
<a href="#version-1-old-version">Version 1</a> of the API). Defaults to <code>false</code>.</li>
<li><code>purge</code> - Optional. If set to <code>true</code>, it will remove all traces of the room from your database.
Defaults to <code>true</code>.</li>
<li><code>force_purge</code> - Optional, and ignored unless <code>purge</code> is <code>true</code>. If set to <code>true</code>, it
will force a purge to go ahead even if there are local users still in the room. Do not
use this unless a regular <code>purge</code> operation fails, as it could leave those users'
clients in a confused state.</li>
</ul>
<p>The JSON body must not be empty. The body must be at least <code>{}</code>.</p>
<h2 id="status-of-deleting-rooms"><a class="header" href="#status-of-deleting-rooms">Status of deleting rooms</a></h2>

<h2 id="undoing-room-deletions"><a class="header" href="#undoing-room-deletions">Undoing room deletions</a></h2>
<p><em>Note</em>: This guide may be outdated by the time you read it. By nature of room deletions being performed at the database level,
the structure can and does change without notice.</p>
<p>First, it's important to understand that a room deletion is very destructive. Undoing a deletion 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:</p>
<ul>
<li>If the room was invite-only, your users will need to be re-invited.</li>
<li>If the room no longer has any members at all, it'll be impossible to rejoin.</li>
<li>The first user to rejoin will have to do so via an alias on a different
server (or receive an invite from a user on a different server).</li>
</ul>
<p>With all that being said, if you still want to try and recover the room:</p>
<ol>
<li>
<p>If the room was <code>block</code>ed, you must unblock it on your server. This can be
accomplished as follows:</p>
<ol>
<li>For safety reasons, shut down Synapse.</li>
<li>In the database, run <code>DELETE FROM blocked_rooms WHERE room_id = '!example:example.org';</code>
<ul>
<li>For caution: it's recommended to run this in a transaction: <code>BEGIN; DELETE ...;</code>, verify you got 1 result, then <code>COMMIT;</code>.</li>
<li>The room ID is the same one supplied to the delete room API, not the Content Violation room.</li>
</ul>
</li>
<li>Restart Synapse.</li>
</ol>
<p>This step is unnecessary if <code>block</code> was not set.</p>
</li>
<li>
<p>Any room aliases on your server that pointed to the deleted room may have
been deleted, or redirected to the Content Violation room. These will need
to be restored manually.</p>
</li>
<li>
<p>Users on your server that were in the deleted room will have been kicked
from the room. Consider whether you want to update their membership
(possibly via the <a href="room_membership.html">Edit Room Membership API</a>) or let
them handle rejoining themselves.</p>
</li>
<li>
<p>If <code>new_room_user_id</code> was given, a 'Content Violation' will have been
created. Consider whether you want to delete that roomm.</p>
</li>
</ol>
<h1 id="make-room-admin-api"><a class="header" href="#make-room-admin-api">Make Room Admin API</a></h1>
<p>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.</p>
<p>By default the server admin (the caller) is granted power, but another user can
optionally be specified, e.g.:</p>
<pre><code>POST /_synapse/admin/v1/rooms/<room_id_or_alias>/make_room_admin
