Account validity callbacks can be registered using the module API's <code>register_account_validity_callbacks</code> method.</p> <p>The available account validity callbacks are:</p> <h3 id="is_user_expired"><a class="header" href="#is_user_expired"><code>is_user_expired</code></a></h3> <p><em>First introduced in Synapse v1.39.0</em></p> <pre><code class="language-python">async def is_user_expired(user: str) -> Optional[bool] </code></pre> <p>Called when processing any authenticated request (except for logout requests). The module can return a <code>bool</code> to indicate whether the user has expired and should be locked out of their account, or <code>None</code> if the module wasn't able to figure it out. The user is represented by their Matrix user ID (e.g. <code>@alice:example.com</code>).</p> <p>If the module returns <code>True</code>, the current request will be denied with the error code <code>ORG_MATRIX_EXPIRED_ACCOUNT</code> and the HTTP status code 403. Note that this doesn't invalidate the user's access token.</p> <p>If multiple modules implement this callback, they will be considered in order. If a callback returns <code>None</code>, Synapse falls through to the next one. The value of the first callback that does not return <code>None</code> will be used. If this happens, Synapse will not call any of the subsequent implementations of this callback.</p> <h3 id="on_user_registration"><a class="header" href="#on_user_registration"><code>on_user_registration</code></a></h3> <p><em>First introduced in Synapse v1.39.0</em></p> <pre><code class="language-python">async def on_user_registration(user: str) -> None </code></pre> <p>Called after successfully registering a user, in case the module needs to perform extra operations to keep track of them.
