Cancel booking
Workflow description
To cancel an existing booking of an airline, the client must send the IATA_OrderCancelRQ message including the “OrderID” of the booking.
If the “OrderID” is unknown, the client can search for an existing booking (see Search bookings for more details).
The API will return an IATA_OrderCancelRS indicating the result of the operation. In case there was an error, the response will contain an “Error”-element. Otherwise, the response will only contain the order ID.
