<h1 id="querying-media"><a class="header" href="#querying-media">Querying media</a></h1>
<p>These APIs allow extracting media information from the homeserver.</p>
<p>Details about the format of the <code>media_id</code> and storage of the media in the file system
are documented under <a href="../media_repository.html">media repository</a>.</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>
<h2 id="list-all-media-in-a-room"><a class="header" href="#list-all-media-in-a-room">List all media in a room</a></h2>
<p>This API gets a list of known media in a room.
However, it only shows media from unencrypted events or rooms.</p>
<p>The API is:</p>
<pre><code>GET /_synapse/admin/v1/room/&lt;room_id&gt;/media
</code></pre>
<p>The API returns a JSON body like the following:</p>
<pre><code class="language-json">{
&quot;local&quot;: [
&quot;mxc://localhost/xwvutsrqponmlkjihgfedcba&quot;,
&quot;mxc://localhost/abcdefghijklmnopqrstuvwx&quot;
],
&quot;remote&quot;: [
&quot;mxc://matrix.org/xwvutsrqponmlkjihgfedcba&quot;,
&quot;mxc://matrix.org/abcdefghijklmnopqrstuvwx&quot;
]
}
</code></pre>
<h2 id="list-all-media-uploaded-by-a-user"><a class="header" href="#list-all-media-uploaded-by-a-user">List all media uploaded by a user</a></h2>
<p>Listing all media that has been uploaded by a local user can be achieved through
the use of the
<a href="user_admin_api.html#list-media-uploaded-by-a-user">List media uploaded by a user</a>
Admin API.</p>
<h1 id="quarantine-media"><a class="header" href="#quarantine-media">Quarantine media</a></h1>
<p>Quarantining media means that it is marked as inaccessible by users. It applies
to any local media, and any locally-cached copies of remote media.</p>
<p>The media file itself (and any thumbnails) is not deleted from the server.</p>
<h2 id="quarantining-media-by-id"><a class="header" href="#quarantining-media-by-id">Quarantining media by ID</a></h2>
<p>This API quarantines a single piece of local or remote media.</p>
<p>Request:</p>
<pre><code>POST /_synapse/admin/v1/media/quarantine/&lt;server_name&gt;/&lt;media_id&gt;
{}
</code></pre>
<p>Where <code>server_name</code> is in the form of <code>example.org</code>, and <code>media_id</code> is in the
form of <code>abcdefg12345...</code>.</p>
<p>Response:</p>
<pre><code class="language-json">{}
</code></pre>
<h2 id="remove-media-from-quarantine-by-id"><a class="header" href="#remove-media-from-quarantine-by-id">Remove media from quarantine by ID</a></h2>
<p>This API removes a single piece of local or remote media from quarantine.</p>
<p>Request:</p>
<pre><code>POST /_synapse/admin/v1/media/unquarantine/&lt;server_name&gt;/&lt;media_id&gt;
{}
</code></pre>
<p>Where <code>server_name</code> is in the form of <code>example.org</code>, and <code>media_id</code> is in the
form of <code>abcdefg12345...</code>.</p>
<p>Response:</p>
<pre><code class="language-json">{}
</code></pre>
<h2 id="quarantining-media-in-a-room"><a class="header" href="#quarantining-media-in-a-room">Quarantining media in a room</a></h2>
<p>This API quarantines all local and remote media in a room.</p>
<p>Request:</p>
<pre><code>POST /_synapse/admin/v1/room/&lt;room_id&gt;/media/quarantine
{}
</code></pre>
<p>Where <code>room_id</code> is in the form of <code>!roomid12345:example.org</code>.</p>
<p>Response:</p>
<pre><code class="language-json">{
&quot;num_quarantined&quot;: 10
}
</code></pre>
<p>The following fields are returned in the JSON response body:</p>
<ul>
<li><code>num_quarantined</code>: integer - The number of media items successfully quarantined</li>
</ul>
<p>Note that there is a legacy endpoint, <code>POST /_synapse/admin/v1/quarantine_media/&lt;room_id&gt;</code>, that operates the same.
However, it is deprecated and may be removed in a future release.</p>
<h2 id="quarantining-all-media-of-a-user"><a class="header" href="#quarantining-all-media-of-a-user">Quarantining all media of a user</a></h2>
<p>This API quarantines all <em>local</em> media that a <em>local</em> user has uploaded. That is to say, if
you would like to quarantine media uploaded by a user on a remote homeserver, you should
instead use one of the other APIs.</p>
<p>Request:</p>
<pre><code>POST /_synapse/admin/v1/user/&lt;user_id&gt;/media/quarantine
{}
</code></pre>
<p>URL Parameters</p>
<ul>

</ul>
<h2 id="protecting-media-from-being-quarantined"><a class="header" href="#protecting-media-from-being-quarantined">Protecting media from being quarantined</a></h2>
<p>This API protects a single piece of local media from being quarantined using the
above APIs. This is useful for sticker packs and other shared media which you do
not want to get quarantined, especially when
<a href="#quarantining-media-in-a-room">quarantining media in a room</a>.</p>
<p>Request:</p>
<pre><code>POST /_synapse/admin/v1/media/protect/&lt;media_id&gt;
{}
</code></pre>
<p>Where <code>media_id</code> is in the form of <code>abcdefg12345...</code>.</p>
