Booking Management APIs

These APIs can be leveraged by any partner, but in order to access booked itineraries the partner will either have to be in possession of data that was only available at the time of booking, or provide a means for the booked traveler to input the required booking data.

At this time XAP does not support cancellation via API, though it is in the backlog. All bookings, whether by Expedia website or API, may be canceled on the Expedia website on which it was booked, or via a call to Expedia Customer Service.

Booking Retrieve	Retrieves the details of an Expedia booking (whether booking was done via Booking API or on an Expedia website)	No	Partners that are providing booked travel info to customers, or else qualifying partners that need access to customer booking data for reporting.
