# 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. ### **Supported Events** The following tracker events are currently supported: * [Overspeed event](/live-tracking-apis/events/create-events/overspeed-event.md) * [Low battery event](/live-tracking-apis/events/create-events/low-battery-event.md) * [No movement event](/live-tracking-apis/events/create-events/no-movement-event.md) * [No signal event](/live-tracking-apis/events/create-events/no-signal-event.md) * [Geofence in event](/live-tracking-apis/events/create-events/geofence-in-event.md) * [Geofence out event](/live-tracking-apis/events/create-events/geofence-out-event.md) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
