The /cars API collection
Our Demand API has a collection of endpoints that allow access to Booking.com's car rental inventory, when implementing the Search and look flow.
With /cars endpoints you can retrieve information about cars, suppliers, depots and even get the score breakdown assigned to a depot based on customer ratings.
Similar to accommodations, this is the overall flow for car rentals:
These are the main actions and involved endpoints:
Action | Endpoint | Result |
|---|---|---|
| Search for vehicles | /cars/search | Travellers see the price and details about the full list of available vehicles for the route they are interested on. |
| Look at details | /cars/suppliers /cars/depots /cars/details | Travellers look at the vehicles, suppliers and depots details. They can also see specific supplier details. |
| Redirect to booking | URL from /cars/search response | Travellers can book their car rental directly from cars.booking.com |
Use the /cars API in your client application so your travellers can search and look at car rentals provided by Booking.com.
