This API is used for order payment & ticket issue. Make payments and request ticketing by calling the Ticketing API. Partner calls this API to inform FR24 to deduct balance for the order requested. If the API call successfully, the payment completed successfully. The ticket number will be obtained via OrderChangeInforming API, or via the OrderDetail API. After the order is created, the order has to be paid within payment deadline, otherwise the order will be canceled. Note: Requesting the API of Ticketing successfully only means FR24 has received the ticketing application, and it will be pending rather than being instantly confirmed and issued. FR24 will notify the order status change via orderChangeInforming API if the booking is confirmed and the ticket can be issued.
