<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 "Authorization: Bearer <access_token>" <the_rest_of_your_API_request>
</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 "Authorization: Bearer syt_AjfVef2_L33JNpafeif_0feKJfeaf0CQpoZk" -X GET http://127.0.0.1:8008/_synapse/admin/v2/users/@foo:bar.com
</code></pre>
<p>For more details on access tokens in Matrix, please refer to the complete
<a href="https://matrix.org/docs/spec/client_server/r0.6.1#using-access-tokens">matrix spec documentation</a>.</p>
