- <p>Account data callbacks allow module developers to react to changes of the account data
- of local users. Account data callbacks can be registered using the module API's
- <code>register_account_data_callbacks</code> method.</p>
- <h2 id="callbacks"><a class="header" href="#callbacks">Callbacks</a></h2>
- <p>The available account data callbacks are:</p>
- <h3 id="on_account_data_updated"><a class="header" href="#on_account_data_updated"><code>on_account_data_updated</code></a></h3>
- <p><em>First introduced in Synapse v1.57.0</em></p>
- <pre><code class="language-python">async def on_account_data_updated(
- user_id: str,
- room_id: Optional[str],
- account_data_type: str,
- content: "synapse.module_api.JsonDict",
- ) -> None:
- </code></pre>
- <p>Called after user's account data has been updated. The module is given the
- Matrix ID of the user whose account data is changing, the room ID the data is associated
- with, the type associated with the change, as well as the new content. If the account
- data is not associated with a specific room, then the room ID is <code>None</code>.</p>
- <p>This callback is triggered when new account data is added or when the data associated with
- a given type (and optionally room) changes. This includes deletion, since in Matrix,
- deleting account data consists of replacing the data associated with a given type
- (and optionally room) with an empty dictionary (<code>{}</code>).</p>
- <p>Note that this doesn't trigger when changing the tags associated with a room, as these are
- processed separately by Synapse.</p>
- <p>If multiple modules implement this callback, Synapse runs them all in order.</p>
- <h2 id="example"><a class="header" href="#example">Example</a></h2>
