setAttendance( )

Sets or updates attendance information for a booking session. This information is stored in an attendance object.

If an attendance object already exists for the session, it's updated. Otherwise, a new object is created.

By default, numberOfAttendees is set to 1, but you can specify a higher number if multiple participants attended. Do not set numberOfAttendees to 0 to indicate no attendance, instead specify {"status": "NOT_ATTENDED"}.

Validation guidelines:

• The call succeeds for mismatches between numberOfAttendees and status. For example, make sure that your code doesn't specify {"status": "NOT_ATTENDED"} with {"numberOfAttendees": 5}.
• The API also allows numberOfAttendees to exceed the booking's numberOfParticipants. Use higher values only when scenarios like walk-ins justify the exception.
