# Embed events

## Actions/Events

You can listen to an event that occurs in embed as follows. We use the term Action and Event interchangeably. Though the technically better term is `event`, it can be confused with booking events or event-types.

```html
<script>
Cal("on", {
  action: "ANY_ACTION_NAME",
  callback: (e)=>{
    // `data` is properties for the event.
    // `type` is the name of the action(You can also call it type of the action.) This would be same as "ANY_ACTION_NAME" except when ANY_ACTION_NAME="*" which listens to all the events.
    // `namespace` tells you the Cal namespace for which the event is fired/
    const {data, type, namespace} = e.detail;
  }
})
</script>
```

### Following are the list of supported events that embed fires.
