+Admin APIs
+==========
+
+**Note**: The latest documentation can be viewed `here <https://matrix-org.github.io/synapse>`_.
+See `docs/README.md <../README.md>`_ for more information.
+
+**Please update links to point to the website instead.** Existing files in this directory
+are preserved to maintain historical links, but may be moved in the future.
+
+This directory includes documentation for the various synapse specific admin
+APIs available. Updates to the existing Admin API documentation should still
+be made to these files, but any new documentation files should instead be placed under
+`docs/usage/administration/admin_api <../usage/administration/admin_api>`_.

+<p>This API allows a server administrator to manage the validity of an account. To
+use it, you must enable the account validity feature (under
+<code>account_validity</code>) in Synapse's configuration.</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="renew-account"><a class="header" href="#renew-account">Renew account</a></h2>
+<p>This API extends the validity of an account by as much time as configured in the
+<code>period</code> parameter from the <code>account_validity</code> configuration.</p>
+<p>The API is:</p>
+<pre><code>POST /_synapse/admin/v1/account_validity/validity
+</code></pre>
+<p>with the following body:</p>
+<pre><code class="language-json">{
+    &quot;user_id&quot;: &quot;&lt;user ID for the account to renew&gt;&quot;,
+    &quot;expiration_ts&quot;: 0,
+    &quot;enable_renewal_emails&quot;: true
+}
+</code></pre>
+<p><code>expiration_ts</code> is an optional parameter and overrides the expiration date,
+which otherwise defaults to now + validity period.</p>
+<p><code>enable_renewal_emails</code> is also an optional parameter and enables/disables
+sending renewal emails to the user. Defaults to true.</p>
+<p>The API returns with the new expiration date for this account, as a timestamp in
+milliseconds since epoch:</p>
+<pre><code class="language-json">{
+    &quot;expiration_ts&quot;: 0
+}
+</code></pre>

+<p>The purge history API allows server admins to purge historic events from their
+database, reclaiming disk space.</p>
+<p>Depending on the amount of history being purged a call to the API may take
+several minutes or longer. During this period users will not be able to
+paginate further back in the room from the point being purged from.</p>
+<p>Note that Synapse requires at least one message in each room, so it will never
+delete the last message in a room.</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>The API is:</p>
+<pre><code>POST /_synapse/admin/v1/purge_history/&lt;room_id&gt;[/&lt;event_id&gt;]
+</code></pre>
+<p>By default, events sent by local users are not deleted, as they may represent
+the only copies of this content in existence. (Events sent by remote users are
+deleted.)</p>
+<p>Room state data (such as joins, leaves, topic) is always preserved.</p>
+<p>To delete local message events as well, set <code>delete_local_events</code> in the body:</p>
+<pre><code class="language-json">{
+   &quot;delete_local_events&quot;: true
+}
+</code></pre>
+<p>The caller must specify the point in the room to purge up to. This can be
+specified by including an event_id in the URI, or by setting a
+<code>purge_up_to_event_id</code> or <code>purge_up_to_ts</code> in the request body. If an event
+id is given, that event (and others at the same graph depth) will be retained.
+If <code>purge_up_to_ts</code> is given, it should be a timestamp since the unix epoch,
+in milliseconds.</p>
+<p>The API starts the purge running, and returns immediately with a JSON body with
+a purge id:</p>
+<pre><code class="language-json">{
+    &quot;purge_id&quot;: &quot;&lt;opaque id&gt;&quot;
+}
+</code></pre>
+<h2 id="purge-status-query"><a class="header" href="#purge-status-query">Purge status query</a></h2>
+<p>It is possible to poll for updates on recent purges with a second API;</p>
+<pre><code>GET /_synapse/admin/v1/purge_history_status/&lt;purge_id&gt;
+</code></pre>
+<p>This API returns a JSON body like the following:</p>
+<pre><code class="language-json">{
+    &quot;status&quot;: &quot;active&quot;
+}
+</code></pre>
+<p>The status will be one of <code>active</code>, <code>complete</code>, or <code>failed</code>.</p>
+<p>If <code>status</code> is <code>failed</code> there will be a string <code>error</code> with the error message.</p>
+<h2 id="reclaim-disk-space-postgres"><a class="header" href="#reclaim-disk-space-postgres">Reclaim disk space (Postgres)</a></h2>
+<p>To reclaim the disk space and return it to the operating system, you need to run
+<code>VACUUM FULL;</code> on the database.</p>

+<p>This API allows for the creation of users in an administrative and
+non-interactive way. This is generally used for bootstrapping a Synapse
+instance with administrator accounts.</p>
+<p>To authenticate yourself to the server, you will need both the shared secret
+(<code>registration_shared_secret</code> in the homeserver configuration), and a
+one-time nonce. If the registration shared secret is not configured, this API
+is not enabled.</p>
+<p>To fetch the nonce, you need to request one from the API:</p>
+<pre><code>&gt; GET /_synapse/admin/v1/register
+
+&lt; {&quot;nonce&quot;: &quot;thisisanonce&quot;}
+</code></pre>
+<p>Once you have the nonce, you can make a <code>POST</code> to the same URL with a JSON
+body containing the nonce, username, password, whether they are an admin
+(optional, False by default), and a HMAC digest of the content. Also you can
+set the displayname (optional, <code>username</code> by default).</p>
+<p>As an example:</p>
+<pre><code>&gt; POST /_synapse/admin/v1/register
+&gt; {
+   &quot;nonce&quot;: &quot;thisisanonce&quot;,
+   &quot;username&quot;: &quot;pepper_roni&quot;,
+   &quot;displayname&quot;: &quot;Pepper Roni&quot;,
+   &quot;password&quot;: &quot;pizza&quot;,
+   &quot;admin&quot;: true,
+   &quot;mac&quot;: &quot;mac_digest_here&quot;
+  }
+
+&lt; {
+   &quot;access_token&quot;: &quot;token_here&quot;,
+   &quot;user_id&quot;: &quot;@pepper_roni:localhost&quot;,
+   &quot;home_server&quot;: &quot;test&quot;,
+   &quot;device_id&quot;: &quot;device_id_here&quot;
+  }
+</code></pre>
+<p>The MAC is the hex digest output of the HMAC-SHA1 algorithm, with the key being
+the shared secret and the content being the nonce, user, password, either the
+string &quot;admin&quot; or &quot;notadmin&quot;, and optionally the user_type
+each separated by NULs. For an example of generation in Python:</p>
+<pre><code class="language-python">import hmac, hashlib
+
+def generate_mac(nonce, user, password, admin=False, user_type=None):
+
+    mac = hmac.new(
+      key=shared_secret,
+      digestmod=hashlib.sha1,
+    )
+
+    mac.update(nonce.encode('utf8'))
+    mac.update(b&quot;\x00&quot;)
+    mac.update(user.encode('utf8'))
+    mac.update(b&quot;\x00&quot;)
+    mac.update(password.encode('utf8'))
+    mac.update(b&quot;\x00&quot;)
+    mac.update(b&quot;admin&quot; if admin else b&quot;notadmin&quot;)
+    if user_type:
+        mac.update(b&quot;\x00&quot;)
+        mac.update(user_type.encode('utf8'))
+
+    return mac.hexdigest()
+</code></pre>

+<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: [&quot;public&quot;, &quot;knock&quot;, &quot;invite&quot;, &quot;private&quot;].</li>
+<li><code>guest_access</code> - Whether guests can join the room. One of: [&quot;can_join&quot;, &quot;forbidden&quot;].</li>
+<li><code>history_visibility</code> - Who can see the room history. One of: [&quot;invited&quot;, &quot;joined&quot;, &quot;shared&quot;, &quot;world_readable&quot;].</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 &quot;next page&quot; 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 &quot;previous page&quot; of results.</li>
+</ul>

+<p>The Delete Room admin API allows server admins to remove rooms from the server

+<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.

+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>

+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'

+<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>

+<p>The API to send notices is as follows:</p>
+<pre><code>POST /_synapse/admin/v1/send_server_notice
+</code></pre>
+<p>or:</p>
+<pre><code>PUT /_synapse/admin/v1/send_server_notice/{txnId}
+</code></pre>
+<p>You will need to authenticate with an access token for an admin user.</p>
+<p>When using the <code>PUT</code> form, retransmissions with the same transaction ID will be
+ignored in the same way as with <code>PUT /_matrix/client/r0/rooms/{roomId}/send/{eventType}/{txnId}</code>.</p>
+<p>The request body should look something like the following:</p>
+<pre><code class="language-json">{
+    &quot;user_id&quot;: &quot;@target_user:server_name&quot;,
+    &quot;content&quot;: {
+        &quot;msgtype&quot;: &quot;m.text&quot;,
+        &quot;body&quot;: &quot;This is my message&quot;
+    }
+}
+</code></pre>
+<p>You can optionally include the following additional parameters:</p>
+<ul>
+<li><code>type</code>: the type of event. Defaults to <code>m.room.message</code>.</li>
+<li><code>state_key</code>: Setting this will result in a state event being sent.</li>
+</ul>
+<p>Once the notice has been sent, the API will return the following response:</p>
+<pre><code class="language-json">{
+    &quot;event_id&quot;: &quot;&lt;event_id&gt;&quot;
+}
+</code></pre>
+<p>Note that server notices must be enabled in <code>homeserver.yaml</code> before this API
+can be used. See <a href="../server_notices.html">the server notices documentation</a> for more information.</p>

+<p>Returns information about all local media usage of users. Gives the
+possibility to filter them by time and user.</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>The API is:</p>
+<pre><code>GET /_synapse/admin/v1/statistics/users/media
+</code></pre>
+<p>A response body like the following is returned:</p>
+<pre><code class="language-json">{
+  &quot;users&quot;: [
+    {
+      &quot;displayname&quot;: &quot;foo_user_0&quot;,
+      &quot;media_count&quot;: 2,
+      &quot;media_length&quot;: 134,
+      &quot;user_id&quot;: &quot;@foo_user_0:test&quot;
+    },
+    {
+      &quot;displayname&quot;: &quot;foo_user_1&quot;,
+      &quot;media_count&quot;: 2,
+      &quot;media_length&quot;: 134,
+      &quot;user_id&quot;: &quot;@foo_user_1:test&quot;
+    }
+  ],
+  &quot;next_token&quot;: 3,
+  &quot;total&quot;: 10
+}
+</code></pre>
+<p>To paginate, check for <code>next_token</code> and if present, call the endpoint
+again with <code>from</code> set to the value of <code>next_token</code>. This will return a new page.</p>
+<p>If the endpoint does not return a <code>next_token</code> then there are no more
+reports to paginate through.</p>
+<p><strong>Parameters</strong></p>
+<p>The following parameters should be set in the URL:</p>
+<ul>
+<li><code>limit</code>: string representing a positive integer - Is optional but is
+used for pagination, denoting the maximum number of items to return
+in this call. Defaults to <code>100</code>.</li>
+<li><code>from</code>: string representing a positive integer - Is optional but used for pagination,
+denoting the offset in the returned results. This should be treated as an opaque value
+and not explicitly set to anything other than the return value of <code>next_token</code> from a
+previous call. Defaults to <code>0</code>.</li>
+<li><code>order_by</code> - string - The method in which to sort the returned list of users. Valid values are:
+<ul>
+<li><code>user_id</code> - Users are ordered alphabetically by <code>user_id</code>. This is the default.</li>
+<li><code>displayname</code> - Users are ordered alphabetically by <code>displayname</code>.</li>
+<li><code>media_length</code> - Users are ordered by the total size of uploaded media in bytes.
+Smallest to largest.</li>
+<li><code>media_count</code> - Users are ordered by number of uploaded media. Smallest to largest.</li>
+</ul>
+</li>
+<li><code>from_ts</code> - string representing a positive integer - Considers only
+files created at this timestamp or later. Unix timestamp in ms.</li>
+<li><code>until_ts</code> - string representing a positive integer - Considers only
+files created at this timestamp or earlier. Unix timestamp in ms.</li>
+<li><code>search_term</code> - string - Filter users by their user ID localpart <strong>or</strong> displayname.
+The search term can be found in any part of the string.
+Defaults to no filtering.</li>
+<li><code>dir</code> - string - Direction of 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>.</li>
+</ul>
+<p><strong>Response</strong></p>
+<p>The following fields are returned in the JSON response body:</p>
+<ul>
+<li><code>users</code> - An array of objects, each containing information
+about the user and their local media. Objects contain the following fields:
+<ul>
+<li><code>displayname</code> - string - Displayname of this user.</li>
+<li><code>media_count</code> - integer - Number of uploaded media by this user.</li>
+<li><code>media_length</code> - integer - Size of uploaded media in bytes by this user.</li>
+<li><code>user_id</code> - string - Fully-qualified user ID (ex. <code>@user:server.com</code>).</li>
+</ul>
+</li>
+<li><code>next_token</code> - integer - Opaque value used for pagination. See above.</li>
+<li><code>total</code> - integer - Total number of users after filtering.</li>
+</ul>

+that contain this value. This parameter is ignored when using the <code>name</code> parameter.</p>
+</li>
+<li>
+<p><code>name</code> - Is optional and filters to only return users with user ID localparts
+<strong>or</strong> displaynames that contain this value.</p>
+</li>
+<li>
+<p><code>guests</code> - string representing a bool - Is optional and if <code>false</code> will <strong>exclude</strong> guest users.
+Defaults to <code>true</code> to include guest users.</p>
+</li>
+<li>
+<p><code>deactivated</code> - string representing a bool - Is optional and if <code>true</code> will <strong>include</strong> deactivated users.
+Defaults to <code>false</code> to exclude deactivated users.</p>
+</li>
+<li>
+<p><code>limit</code> - string representing a positive integer - Is optional but is used for pagination,
+denoting the maximum number of items to return in this call. Defaults to <code>100</code>.</p>
+</li>
+<li>
+<p><code>from</code> - string representing a positive integer - Is optional but used for pagination,
+denoting the offset in the returned results. This should be treated as an opaque value and
+not explicitly set to anything other than the return value of <code>next_token</code> from a previous call.
+Defaults to <code>0</code>.</p>
+</li>
+<li>
+<p><code>order_by</code> - The method by which to sort the returned list of users.
+If the ordered field has duplicates, the second order is always by ascending <code>name</code>,
+which guarantees a stable ordering. Valid values are:</p>
+<ul>
+<li><code>name</code> - Users are ordered alphabetically by <code>name</code>. This is the default.</li>
+<li><code>is_guest</code> - Users are ordered by <code>is_guest</code> status.</li>
+<li><code>admin</code> - Users are ordered by <code>admin</code> status.</li>
+<li><code>user_type</code> - Users are ordered alphabetically by <code>user_type</code>.</li>
+<li><code>deactivated</code> - Users are ordered by <code>deactivated</code> status.</li>
+<li><code>shadow_banned</code> - Users are ordered by <code>shadow_banned</code> status.</li>
+<li><code>displayname</code> - Users are ordered alphabetically by <code>displayname</code>.</li>
+<li><code>avatar_url</code> - Users are ordered alphabetically by avatar URL.</li>
+<li><code>creation_ts</code> - Users are ordered by when the users was created in ms.</li>
+</ul>
+</li>
+<li>
+<p><code>dir</code> - Direction of media 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>
+</ul>
+<p>Caution. The database only has indexes on the columns <code>name</code> and <code>creation_ts</code>.
+This means that if a different sort order is used (<code>is_guest</code>, <code>admin</code>,
+<code>user_type</code>, <code>deactivated</code>, <code>shadow_banned</code>, <code>avatar_url</code> or <code>displayname</code>),
+this can cause a large load on the database, especially for large environments.</p>

+<p><strong>Parameters</strong></p>
+<p>The following parameters should be set in the URL:</p>
+<ul>
+<li>
+<p><code>user_id</code> - string - fully qualified: for example, <code>@user:server.com</code>.</p>
+</li>
+<li>
+<p><code>limit</code>: string representing a positive integer - Is optional but is used for pagination,
+denoting the maximum number of items to return in this call. Defaults to <code>100</code>.</p>
+</li>
+<li>
+<p><code>from</code>: string representing a positive integer - Is optional but used for pagination,
+denoting the offset in the returned results. This should be treated as an opaque value and
+not explicitly set to anything other than the return value of <code>next_token</code> from a previous call.
+Defaults to <code>0</code>.</p>
+</li>
+<li>
+<p><code>order_by</code> - The method by which to sort the returned list of media.
+If the ordered field has duplicates, the second order is always by ascending <code>media_id</code>,
+which guarantees a stable ordering. Valid values are:</p>
+<ul>
+<li><code>media_id</code> - Media are ordered alphabetically by <code>media_id</code>.</li>
+<li><code>upload_name</code> - Media are ordered alphabetically by name the media was uploaded with.</li>
+<li><code>created_ts</code> - Media are ordered by when the content was uploaded in ms.
+Smallest to largest. This is the default.</li>
+<li><code>last_access_ts</code> - Media are ordered by when the content was last accessed in ms.
+Smallest to largest.</li>
+<li><code>media_length</code> - Media are ordered by length of the media in bytes.
+Smallest to largest.</li>
+<li><code>media_type</code> - Media are ordered alphabetically by MIME-type.</li>
+<li><code>quarantined_by</code> - Media are ordered alphabetically by the user ID that
+initiated the quarantine request for this media.</li>
+<li><code>safe_from_quarantine</code> - Media are ordered by the status if this media is safe
+from quarantining.</li>
+</ul>
+</li>
+<li>
+<p><code>dir</code> - Direction of media 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>
+</ul>
+<p>If neither <code>order_by</code> nor <code>dir</code> is set, the default order is newest media on top
+(corresponds to <code>order_by</code> = <code>created_ts</code> and <code>dir</code> = <code>b</code>).</p>
+<p>Caution. The database only has indexes on the columns <code>media_id</code>,
+<code>user_id</code> and <code>created_ts</code>. This means that if a different sort order is used
+(<code>upload_name</code>, <code>last_access_ts</code>, <code>media_length</code>, <code>media_type</code>,
+<code>quarantined_by</code> or <code>safe_from_quarantine</code>), this can cause a large load on the
+database, especially for large environments.</p>
+<p><strong>Response</strong></p>
+<p>The following fields are returned in the JSON response body:</p>

+<h3 id="delete-media-uploaded-by-a-user"><a class="header" href="#delete-media-uploaded-by-a-user">Delete media uploaded by a user</a></h3>
+<p>This API deletes the <em>local</em> media from the disk of your own server
+that a specific <code>user_id</code> has created. This includes any local thumbnails.</p>
+<p>This API will not affect media that has been uploaded to external
+media repositories (e.g https://github.com/turt2live/matrix-media-repo/).</p>
+<p>By default, the API deletes media ordered by descending creation date and ascending media ID.
+The newest media is deleted first. You can change the order with parameters
+<code>order_by</code> and <code>dir</code>. If no <code>limit</code> is set the API deletes <code>100</code> files per request.</p>
+<p>The API is:</p>
+<pre><code>DELETE /_synapse/admin/v1/users/&lt;user_id&gt;/media
+</code></pre>
+<p>A response body like the following is returned:</p>

+</ul>
+<p><strong>Note</strong>: There is no <code>next_token</code>. This is not useful for deleting media, because
+after deleting media the remaining media have a new order.</p>
+<p><strong>Parameters</strong></p>
+<p>This API has the same parameters as
+<a href="#list-media-uploaded-by-a-user">List media uploaded by a user</a>.
+With the parameters you can for example limit the number of files to delete at once or

+<p>Shadow-banning is a useful tool for moderating malicious or egregiously abusive users.
+A shadow-banned users receives successful responses to their client-server API requests,
+but the events are not propagated into rooms. This can be an effective tool as it
+(hopefully) takes longer for the user to realise they are being moderated before
+pivoting to another account.</p>
+<p>Shadow-banning a user should be used as a tool of last resort and may lead to confusing
+or broken behaviour for the client. A shadow-banned user will not receive any
+notification and it is generally more appropriate to ban or kick abusive users.
+A shadow-banned user will be unable to contact anyone on the server.</p>
+<p>To shadow-ban a user the API is:</p>
+<pre><code>POST /_synapse/admin/v1/users/&lt;user_id&gt;/shadow_ban
+</code></pre>
+<p>To un-shadow-ban a user the API is:</p>
+<pre><code>DELETE /_synapse/admin/v1/users/&lt;user_id&gt;/shadow_ban
+</code></pre>
+<p>An empty JSON dict is returned in both cases.</p>
+<p><strong>Parameters</strong></p>
+<p>The following parameters should be set in the URL:</p>

+<pre><code>GET /_synapse/admin/v1/server_version
