# Events

### Overview

You can assign multiple events to your trackers, and when an event is triggered, notifications are sent based on your configuration. By default, webhooks are always triggered, but you can customize additional notification channels (such as email, SMS, or in-app notifications) during event creation.

Events can also be updated after they have been created.
