Syntax:
https://[domain]/[version]</[xml or json]>/[endpoint]?[parameters]
The API consists of three general endpoint classes:
Availability: Real-time pricing and availability, both of which are constantly changing. This should not be cached, you must request the data each time it is needed.
Static Data: Property descriptions, facility information, city names, hotel types, and other items that change much less frequently than availability.
Booking Endpoints: Endpoints related to processing bookings via the API.
Partners who need to use the API for bookings must be PCI DSS-compliant and have the appropriate contracts in place.
Destination information can be obtained from the following endpoints:
- /countries
- /cities
- /districts
- /regions
Reference endpoints such as /hotelFacilityTypes, /hotelTypes, /chainTypes, and /paymentTypes allow you to obtain supporting data for use in conjunction with other endpoints.
The /hotelAvailability endpoint should generally be used to return the least expensive rooms available that match the provided guest configuration and search parameters.
After a property is selected, /blockAvailability can be used to return all available rooms for a specific property.
