-TODO
+Plugins can register their own custom event types for use with NetBox [event rules](../../models/extras/eventrule.md). This is accomplished by calling the `register()` method on an instance of the `Event` class. This can be done anywhere within the plugin. An example is provided below.
+
+```python
+from django.utils.translation import gettext_lazy as _
+from netbox.events import Event, EVENT_TYPE_SUCCESS
+
+Event(
+    name='ticket_opened',
+    text=_('Ticket opened'),
+    type=EVENT_TYPE_SUCCESS
+).register()
+```
