1.1. GENERAL WORKFLOW
Diagram 1.1.1. GP Travel HUB Transfer Workflow
Transfer flow starts from search for Transfer Availability (TransferAvail).
For Transfer found user can optionally request additional transfer details (TransferDescriptiveInfo), and cancellation charges (TransferCharges).
To proceed with booking of selected transfer user should go with TransferReservation message.
After the transfer is booked it can be further cancelled (Cancellation). At any time it is also possible to retrieve active booking status from supplier (BookingRetrieval).
Note: transfer modification is not available via API since suppliers mostly do not support modification for Transfers. Also, PriceBreakdown message is not applicable as long as normally transfer takes less than a day.
