Car APIs—Car Rental Service On-Demand in Your Applications

If you’re building travel capabilities into a web or mobile application, setting up a travel website or online travel agency (OTA), car rental is an important feature to offer your users. Travelers expect to be able to reserve car rentals in a package, together with airline booking, hotel, and rail or other ground transport.

There are several approaches to offering car rental within your application:

  • Integrate with a Global Distribution System (GDS) like Sabre, TravelPort, or Amadeus. GDS systems aggregate data and enable bookings for multiple travel services, with a global inventory.
  • Integrate with booking services like Expedia or Priceline. These types of services offer travel packages (including airline tickets, hotels, and transport) from a more limited inventory, but often with more competitive pricing than GDS systems.
  • Integrate with a car rental service like RentalCars—in most cases, this will give you the most granular control over car rental orders, and may offer a larger inventory and better prices, depending on location and the provider’s operating regions.
