+<p>This API allows a server administrator to manage the background updates being
+run against the database.</p>
+<h2 id="status"><a class="header" href="#status">Status</a></h2>
+<p>This API gets the current status of the background updates.</p>
+<p>The API is:</p>
+<pre><code>GET /_synapse/admin/v1/background_updates/status
+</code></pre>
+<p>Returning:</p>
+<pre><code class="language-json">{
+    &quot;enabled&quot;: true,
+    &quot;current_updates&quot;: {
+        &quot;&lt;db_name&gt;&quot;: {
+            &quot;name&quot;: &quot;&lt;background_update_name&gt;&quot;,
+            &quot;total_item_count&quot;: 50,
+            &quot;total_duration_ms&quot;: 10000.0,
+            &quot;average_items_per_ms&quot;: 2.2,
+        },
+    }
+}
+</code></pre>
+<p><code>enabled</code> whether the background updates are enabled or disabled.</p>
+<p><code>db_name</code> the database name (usually Synapse is configured with a single database named 'master').</p>
+<p>For each update:</p>
+<p><code>name</code> the name of the update.
+<code>total_item_count</code> total number of &quot;items&quot; processed (the meaning of 'items' depends on the update in question).
+<code>total_duration_ms</code> how long the background process has been running, not including time spent sleeping.
+<code>average_items_per_ms</code> how many items are processed per millisecond based on an exponential average.</p>
+<h2 id="enabled"><a class="header" href="#enabled">Enabled</a></h2>
+<p>This API allow pausing background updates.</p>
+<p>Background updates should <em>not</em> be paused for significant periods of time, as
+this can affect the performance of Synapse.</p>
+<p><em>Note</em>: This won't persist over restarts.</p>
+<p><em>Note</em>: This won't cancel any update query that is currently running. This is
+usually fine since most queries are short lived, except for <code>CREATE INDEX</code>
+background updates which won't be cancelled once started.</p>
+<p>The API is:</p>
+<pre><code>POST /_synapse/admin/v1/background_updates/enabled
+</code></pre>
+<p>with the following body:</p>
+<pre><code class="language-json">{
+    &quot;enabled&quot;: false
+}
+</code></pre>
+<p><code>enabled</code> sets whether the background updates are enabled or disabled.</p>
+<p>The API returns the <code>enabled</code> param.</p>
+<pre><code class="language-json">{
+    &quot;enabled&quot;: false
+}
+</code></pre>
+<p>There is also a <code>GET</code> version which returns the <code>enabled</code> state.</p>
+<h2 id="run"><a class="header" href="#run">Run</a></h2>
+<p>This API schedules a specific background update to run. The job starts immediately after calling the API.</p>
+<p>The API is:</p>
+<pre><code>POST /_synapse/admin/v1/background_updates/start_job
+</code></pre>
+<p>with the following body:</p>
+<pre><code class="language-json">{
+    &quot;job_name&quot;: &quot;populate_stats_process_rooms&quot;
+}
+</code></pre>
+<p>The following JSON body parameters are available:</p>
+<ul>
+<li><code>job_name</code> - A string which job to run. Valid values are:
+<ul>
+<li><code>populate_stats_process_rooms</code> - Recalculate the stats for all rooms.</li>
+<li><code>regenerate_directory</code> - Recalculate the <a href="../../../user_directory.html">user directory</a> if it is stale or out of sync.</li>

+<p>This API allows a server administrator to manage Synapse's federation with other homeservers.</p>
+<p>Note: This API is new, experimental and &quot;subject to change&quot;.</p>
+<h2 id="list-of-destinations"><a class="header" href="#list-of-destinations">List of destinations</a></h2>
+<p>This API gets the current destination retry timing info for all remote servers.</p>
+<p>The list contains all the servers with which the server federates,
+regardless of whether an error occurred or not.
+If an error occurs, it may take up to 20 minutes for the error to be displayed here,
+as a complete retry must have failed.</p>
+<p>The API is:</p>
+<p>A standard request with no filtering:</p>
+<pre><code>GET /_synapse/admin/v1/federation/destinations
+</code></pre>
+<p>A response body like the following is returned:</p>
+<pre><code class="language-json">{
+   &quot;destinations&quot;:[
+      {
+         &quot;destination&quot;: &quot;matrix.org&quot;,
+         &quot;retry_last_ts&quot;: 1557332397936,

+         &quot;failure_ts&quot;: 1557329397936,
+         &quot;last_successful_stream_ordering&quot;: null
+      }
+   ],
+   &quot;total&quot;: 1
+}
+</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 destinations
+to paginate through.</p>
+<p><strong>Parameters</strong></p>
+<p>The following query parameters are available:</p>
+<ul>
+<li><code>from</code> - Offset in the returned list. Defaults to <code>0</code>.</li>
+<li><code>limit</code> - Maximum amount of destinations to return. Defaults to <code>100</code>.</li>
+<li><code>order_by</code> - The method in which to sort the returned list of destinations.
+Valid values are:
+<ul>
+<li><code>destination</code> - Destinations are ordered alphabetically by remote server name.
+This is the default.</li>
+<li><code>retry_last_ts</code> - Destinations are ordered by time of last retry attempt in ms.</li>
+<li><code>retry_interval</code> - Destinations are ordered by how long until next retry in ms.</li>
+<li><code>failure_ts</code> - Destinations are ordered by when the server started failing in ms.</li>
+<li><code>last_successful_stream_ordering</code> - Destinations are ordered by the stream ordering
+of the most recent successfully-sent PDU.</li>
+</ul>
+</li>
+<li><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>.</li>
+</ul>
+<p><em>Caution:</em> The database only has an index on the column <code>destination</code>.
+This means that if a different sort order is used,
+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>
+<ul>
+<li><code>destinations</code> - An array of objects, each containing information about a destination.
+Destination objects contain the following fields:
+<ul>
+<li><code>destination</code> - string - Name of the remote server to federate.</li>
+<li><code>retry_last_ts</code> - integer - The last time Synapse tried and failed to reach the
+remote server, in ms. This is <code>0</code> if the last attempt to communicate with the
+remote server was successful.</li>
+<li><code>retry_interval</code> - integer - How long since the last time Synapse tried to reach
+the remote server before trying again, in ms. This is <code>0</code> if no further retrying occurring.</li>
+<li><code>failure_ts</code> - nullable integer - The first time Synapse tried and failed to reach the
+remote server, in ms. This is <code>null</code> if communication with the remote server has never failed.</li>
+<li><code>last_successful_stream_ordering</code> - nullable integer - The stream ordering of the most
+recent successfully-sent <a href="../understanding_synapse_through_grafana_graphs.html#federation">PDU</a>
+to this destination, or <code>null</code> if this information has not been tracked yet.</li>
+</ul>
+</li>
+<li><code>next_token</code>: string representing a positive integer - Indication for pagination. See above.</li>

+<h2 id="reset-connection-timeout"><a class="header" href="#reset-connection-timeout">Reset connection timeout</a></h2>
+<p>Synapse makes federation requests to other homeservers. If a federation request fails,
+Synapse will mark the destination homeserver as offline, preventing any future requests
+to that server for a &quot;cooldown&quot; period. This period grows over time if the server
+continues to fail its responses
+(<a href="https://en.wikipedia.org/wiki/Exponential_backoff">exponential backoff</a>).</p>
+<p>Admins can cancel the cooldown period with this API.</p>
+<p>This API resets the retry timing for a specific remote server and tries to connect to
+the remote server again. It does not wait for the next <code>retry_interval</code>.
+The connection must have previously run into an error and <code>retry_last_ts</code>
+(<a href="#destination-details-api">Destination Details API</a>) must not be equal to <code>0</code>.</p>
+<p>The connection attempt is carried out in the background and can take a while
+even if the API already returns the http status 200.</p>
+<p>The API is:</p>
+<pre><code>POST /_synapse/admin/v1/federation/destinations/&lt;destination&gt;/reset_connection
+
+{}
+</code></pre>
+<p><strong>Parameters</strong></p>
+<p>The following parameters should be set in the URL:</p>

+<h2 id="authenticate-as-a-server-admin"><a class="header" href="#authenticate-as-a-server-admin">Authenticate as a server admin</a></h2>
+<p>Many of the API calls in the admin api will require an <code>access_token</code> for a
+server admin. (Note that a server admin is distinct from a room admin.)</p>
+<p>An existing user can be marked as a server admin by updating the database directly.</p>
+<p>Check your <a href="../../configuration/config_documentation.html#database">database settings</a> in the configuration file, connect to the correct database using either <code>psql [database name]</code> (if using PostgreSQL) or <code>sqlite3 path/to/your/database.db</code> (if using SQLite) and elevate the user <code>@foo:bar.com</code> to administrator.</p>
+<pre><code class="language-sql">UPDATE users SET admin = 1 WHERE name = '@foo:bar.com';
+</code></pre>
+<p>A new server admin user can also be created using the <code>register_new_matrix_user</code>
+command. This is a script that is distributed as part of synapse. It is possibly
+already on your <code>$PATH</code> depending on how Synapse was installed.</p>
+<p>Finding your user's <code>access_token</code> is client-dependent, but will usually be shown in the client's settings.</p>
+<h2 id="making-an-admin-api-request"><a class="header" href="#making-an-admin-api-request">Making an Admin API request</a></h2>
+<p>For security reasons, we <a href="../../../reverse_proxy.html#synapse-administration-endpoints">recommend</a>
+that the Admin API (<code>/_synapse/admin/...</code>) should be hidden from public view using a
+reverse proxy. This means you should typically query the Admin API from a terminal on
+the machine which runs Synapse.</p>
+<p>Once you have your <code>access_token</code>, you will need to authenticate each request to an Admin API endpoint by
+providing the token as either a query parameter or a request header. To add it as a request header in cURL:</p>
+<pre><code class="language-sh">curl --header &quot;Authorization: Bearer &lt;access_token&gt;&quot; &lt;the_rest_of_your_API_request&gt;
+</code></pre>
+<p>For example, suppose we want to
+<a href="../../../admin_api/user_admin_api.html#query-user-account">query the account</a> of the user
+<code>@foo:bar.com</code>. We need an admin access token (e.g.
+<code>syt_AjfVef2_L33JNpafeif_0feKJfeaf0CQpoZk</code>), and we need to know which port
+Synapse's <a href="../../configuration/config_documentation.html#listeners"><code>client</code> listener</a> is listening
+on (e.g. <code>8008</code>). Then we can use the following command to request the account
+information from the Admin API.</p>
+<pre><code class="language-sh">curl --header &quot;Authorization: Bearer syt_AjfVef2_L33JNpafeif_0feKJfeaf0CQpoZk&quot; -X GET http://127.0.0.1:8008/_synapse/admin/v2/users/@foo:bar.com

+<p><strong>Note:</strong> This API is disabled when MSC3861 is enabled. <a href="https://github.com/matrix-org/synapse/pull/15582">See #15582</a></p>
+<p>This API allows you to manage tokens which can be used to authenticate
+registration requests, as proposed in
+<a href="https://github.com/matrix-org/matrix-doc/blob/main/proposals/3231-token-authenticated-registration.md">MSC3231</a>
+and stabilised in version 1.2 of the Matrix specification.
+To use it, you will need to enable the <code>registration_requires_token</code> config
+option, and authenticate by providing an <code>access_token</code> for a server admin:
+see <a href="../admin_api/">Admin API</a>.</p>
+<h2 id="registration-token-objects"><a class="header" href="#registration-token-objects">Registration token objects</a></h2>
+<p>Most endpoints make use of JSON objects that contain details about tokens.
+These objects have the following fields:</p>
+<ul>
+<li><code>token</code>: The token which can be used to authenticate registration.</li>
+<li><code>uses_allowed</code>: The number of times the token can be used to complete a
+registration before it becomes invalid.</li>
+<li><code>pending</code>: The number of pending uses the token has. When someone uses
+the token to authenticate themselves, the pending counter is incremented
+so that the token is not used more than the permitted number of times.
+When the person completes registration the pending counter is decremented,
+and the completed counter is incremented.</li>
+<li><code>completed</code>: The number of times the token has been used to successfully
+complete a registration.</li>
+<li><code>expiry_time</code>: The latest time the token is valid. Given as the number of
+milliseconds since 1970-01-01 00:00:00 UTC (the start of the Unix epoch).
+To convert this into a human-readable form you can remove the milliseconds
+and use the <code>date</code> command. For example, <code>date -d '@1625394937'</code>.</li>
+</ul>
+<h2 id="list-all-tokens"><a class="header" href="#list-all-tokens">List all tokens</a></h2>
+<p>Lists all tokens and details about them. If the request is successful, the top
+level JSON object will have a <code>registration_tokens</code> key which is an array of
+registration token objects.</p>

+<p>Optional query parameters:</p>

+If <code>false</code>, only tokens that have expired or have had all uses exhausted are
+returned. If omitted, all tokens are returned regardless of validity.</li>
