There are two different statuses that can reflect a cancellation: the event status and the event sales status. The event's status can be "live", while the event's sales status is "sales_ended" with "message_code": "event_cancelled", for example. Both statuses are important to understanding the event's position!
To retrieve an event's sales status, you will need to add the 'event_sales_status' expansion to your request:
