# JavaScript Events

RevenueHero JavaScript events are sent from the scheduler at different stages. Learn about those events that can be used to trigger downstream activities.

The **SaaSMonk Chat Widget** tracks and emits the following JavaScript events through the lifecycle of the chat experience. These can be captured using a sample message listener like the following to be used for actions like sending event to Google Analytics, Pixel, etc.

```javascript
window.addEventListener("message", (ev) => {
  if (ev.data.type == "MEETING_BOOKED") {
    // Send to Google Analytics
    dataLayer.push({ event: "meeting_booked" });

    // Send to pixel
    fbq("track", "RevenueHero", { event: "meeting_booked" });
  }
});
```

### MEETING\_BOOKED

The event is sent when a meeting is booked successfully through a calendar integrated within our widget
