<h1 id="spam-checker-callbacks"><a class="header" href="#spam-checker-callbacks">Spam checker callbacks</a></h1>
<p>Spam checker callbacks allow module developers to implement spam mitigation actions for
Synapse instances. Spam checker callbacks can be registered using the module API’s
<code>register_spam_checker_callbacks</code> method.</p>
<h2 id="callbacks"><a class="header" href="#callbacks">Callbacks</a></h2>
<p>The available spam checker callbacks are:</p>
<h3 id="check_event_for_spam"><a class="header" href="#check_event_for_spam"><code>check_event_for_spam</code></a></h3>
<p><em>First introduced in Synapse v1.37.0</em></p>
<p><em>Changed in Synapse v1.60.0: <code>synapse.module_api.NOT_SPAM</code> and <code>synapse.module_api.errors.Codes</code> can be returned by this callback. Returning a boolean or a string is now deprecated.</em></p>
<pre><code class="language-python">async def check_event_for_spam(event: "synapse.module_api.EventBase") -&gt; Union["synapse.module_api.NOT_SPAM", "synapse.module_api.errors.Codes", str, bool]
</code></pre>
<p>Called when receiving an event from a client or via federation. The callback must return one of:</p>
<ul>
<li><code>synapse.module_api.NOT_SPAM</code>, to allow the operation. Other callbacks may still
decide to reject it.</li>
<li><code>synapse.module_api.errors.Codes</code> to reject the operation with an error code. In case
of doubt, <code>synapse.module_api.errors.Codes.FORBIDDEN</code> is a good error code.</li>
<li>(deprecated) a non-<code>Codes</code> <code>str</code> to reject the operation and specify an error message. Note that clients
typically will not localize the error message to the user’s preferred locale.</li>
<li>(deprecated) <code>False</code>, which is the same as returning <code>synapse.module_api.NOT_SPAM</code>.</li>
<li>(deprecated) <code>True</code>, which is the same as returning <code>synapse.module_api.errors.Codes.FORBIDDEN</code>.</li>
</ul>
<p>If multiple modules implement this callback, they will be considered in order. If a
callback returns <code>synapse.module_api.NOT_SPAM</code>, Synapse falls through to the next one.
The value of the first callback that does not return <code>synapse.module_api.NOT_SPAM</code> will
be used. If this happens, Synapse will not call any of the subsequent implementations of
this callback.</p>
<h3 id="user_may_join_room"><a class="header" href="#user_may_join_room"><code>user_may_join_room</code></a></h3>
<p><em>First introduced in Synapse v1.37.0</em></p>
<p><em>Changed in Synapse v1.61.0: <code>synapse.module_api.NOT_SPAM</code> and <code>synapse.module_api.errors.Codes</code> can be returned by this callback. Returning a boolean is now deprecated.</em></p>
<pre><code class="language-python">async def user_may_join_room(user: str, room: str, is_invited: bool) -&gt; Union["synapse.module_api.NOT_SPAM", "synapse.module_api.errors.Codes", bool]
</code></pre>
<p>Called when a user is trying to join a room. The user is represented by their Matrix user ID (e.g.
<code>@alice:example.com</code>) and the room is represented by its Matrix ID (e.g.
<code>!room:example.com</code>). The module is also given a boolean to indicate whether the user
