Our Demand API offers a wide range of functionalities for Affiliate Partners to be able to retrieve accommodation, car rental and flights information from Booking.com inventory.
- Based on basic REST principles, our endpoints return JSON data directly from our system.
- You can consume them directly through HTTPS calls, using the POST method.
This endpoint returns detailed information on all accommodation properties matching a given search criteria. By default, only basic information is returned.
It is mandatory to pass one of the input parameters: accommodations, airport, city, country or region.
To receive extended information use the extras parameter.
A three-letter code that uniquely identifies an airport as defined by the International Air Transport Association (IATA). The full list can be obtained by calling common/locations/airports.
A signed integer number that uniquely identifies a city. The full list can be obtained by calling common/locations/cities.
A two-letter code that uniquely identifies a country. This code is defined by the ISO 3166-1 alpha-2 standard (ISO2) as described here: https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2. The full list can be obtained by calling common/locations/countries.
Input parameter to request for additional information about the accommodation property. It should be passed as a JSON array with one or more items.
A signed integer number that uniquely identifies a geographical region. Regions usually define official administrative areas within a country, but may also include multiple countries and in some cases un-official but popular designations for geographical areas. An example of a region that crosses multiple countries is the Alps in Europe. The full list can be obtained by calling common/locations/regions.
