<h1 id="deprecated-shutdown-room-api"><a class="header" href="#deprecated-shutdown-room-api">Deprecated: Shutdown room API</a></h1>
<p><strong>The old Shutdown room API is deprecated and will be removed in a future release.
See the new <a href="rooms.html#delete-room-api">Delete Room API</a> for more details.</strong></p>
<p>Shuts down a room, preventing new joins and moves local users and room aliases automatically
to a new room. 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
-10 by default, and thus be unable to speak. The old room's power levels will be changed to
disallow any further invites or joins.</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="api"><a class="header" href="#api">API</a></h2>
<p>You will need to authenticate with an access token for an admin user.</p>
<h3 id="url"><a class="header" href="#url">URL</a></h3>
<p><code>POST /_synapse/admin/v1/shutdown_room/{room_id}</code></p>
<h3 id="url-parameters"><a class="header" href="#url-parameters">URL Parameters</a></h3>
<ul>
<li><code>room_id</code> - The ID of the room (e.g <code>!someroom:example.com</code>)</li>
</ul>
<h3 id="json-body-parameters"><a class="header" href="#json-body-parameters">JSON Body Parameters</a></h3>
<ul>
<li><code>new_room_user_id</code> - Required. A string representing the user ID of the user that will admin
the new room that all users in the old room will be moved to.</li>
<li><code>room_name</code> - Optional. A string representing the name of the room that new users will be
invited to.</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.</li>
</ul>
<p>If not specified, the default value of <code>room_name</code> is "Content Violation
Notification". The default value of <code>message</code> is "Sharing illegal content on
othis server is not permitted and rooms in violation will be blocked."</p>
<h3 id="response-parameters"><a class="header" href="#response-parameters">Response Parameters</a></h3>
<ul>
<li><code>kicked_users</code> - An integer number representing the number of users that
were kicked.</li>
<li><code>failed_to_kick_users</code> - An integer number representing the number of users
that were not kicked.</li>
<li><code>local_aliases</code> - An array of strings representing the local aliases that were migrated from
the old room to the new.</li>
<li><code>new_room_id</code> - A string representing the room ID of the new room.</li>
</ul>
<h2 id="example"><a class="header" href="#example">Example</a></h2>
<p>Request:</p>
<pre><code>POST /_synapse/admin/v1/shutdown_room/!somebadroom%3Aexample.com
{
"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."
}
</code></pre>
<p>Response:</p>
<pre><code>{
"kicked_users": 5,
"failed_to_kick_users": 0,
"local_aliases": ["#badroom:example.com", "#evilsaloon:example.com],
"new_room_id": "!newroomid:example.com",

</code></pre>
<h2 id="undoing-room-shutdowns"><a class="header" href="#undoing-room-shutdowns">Undoing room shutdowns</a></h2>
<p><em>Note</em>: 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.</p>
<p>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:</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.</li>
</ul>
<p>With all that being said, if you still want to try and recover the room:</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 shutdown room API, not the Content Violation room.</li>
</ul>
</li>
<li>Restart Synapse.</li>
</ol>
<p>You will have to manually handle, if you so choose, the following:</p>
<ul>
<li>Aliases that would have been redirected to the Content Violation room.</li>
<li>Users that would have been booted from the room (and will have been force-joined to the Content Violation room).</li>
<li>Removal of the Content Violation room if desired.</li>
</ul>
