# Classes

The example shows the **Class Booked**, however, the payload format is similar for other updates such as **Waitlisted, Visited, Resechduled, No-Show** and **Cancelled.**

## Class Participant Updates

**(i) Payload Format:** This is an example of the **Class Booked** Payload data format and content that Whautomate will transmit to the configured endpoint. All other Class Participant Updates follow similar payload format.
