Typical use case of message exchange flow between Providers and Sellers can be resumed as:
Synchronize Hotelier product:
Providers retrieve static inventory (Hotel/Rate Plans/Rooms) from Seller using HotelRatePlanInventoryRetrieve in order to map Hotelier inventory into their system.
Providers Push/Notif Rate Plan information to Seller using HotelRatePlanNotif in order to synchronize Hotelier rates.
Providers Push/Notif Availability information to Seller using HotelAvailNotif in order to synchronize Hotelier availability.
Synchronize Bookings (Confirmations / Cancellations):
XTG can Push/Notify reservations and cancellations to Providers using HotelResNotif and CancelNotif.
Providers can retrieve reservations using HotelResRetrieve.
Use both systems as described above.
Optionally, check if synchronization is correct:
Providers retrieve dynamic rates using HotelRatePlanRetrieve.
Providers retrieve availability using HotelAvailRetrieve.
