Car Rental and Sharing APIs: Integrations with GDSs, OTAs, and Tech Providers

Exploring foreign places in a rental car offers multiple perks: You can get far off the beaten path, avoid wasting time trying to figure out public transportation or limiting your itinerary in case of a poor local transit system. As travel restrictions ease, the car rental market keeps growing with about 9 percent CAGR.

Since car rental is an integral part of the travel industry, it clearly makes sense to tie it into your travel or hospitality service. And Application Programming Interfaces or APIs can help you connect the dots fetching the necessary info. For clarity, check our video explaining how API enables connectivity in travel systems.

In our article on the fundamentals of travel APIs, we briefly address the car rental industry. Now, we’ll expand on this topic by introducing major car rental API providers currently on the market, and their features that you can benefit from.


Overview of the main car rental APIs

GDS car rental APIs: Sabre, Amadeus, Travelport

Standing at the core of the reservation network, global distribution systems (GDSs) store and retrieve travel-related data, further sharing it with travel agents, booking engines, etc., through their proprietary web services APIs. The car rental GDS landscape consists of Sabre, Amadeus, and Travelport.

Sabre APIs

This leading travel tech solutions provider covers a range of travel sectors, including over 37 car rental brands in about 40 thousand locations. Sabre offers several car APIs to locate, choose, and book vehicles from their inventory. This  set of interfaces can be divided into several key services:
  • Car rental location found by city codes and vendor search
  • Vehicle availability, types, and rates
  • Booking cars and modifying those reservations
Geo Search API can also be used to find car rental whereabouts, specifically:
  • geo search using custom radius
  • polygon search in a precise area returning specific and relevant results
  • distance between the resolved locations.
Sabre also enables reserving a vehicle with additional info like flight arrival information, customer address, different return location, etc.

Amadeus APIs

Amadeus’ main set of APIs covers multiple distribution types, car rentals included. To access Amadeus content, register your account and then get a unique API key that you’ll provide in API calls.

Similar to Sabre, you can get locations, rates, availability, and booking. Besides car rentals, Amadeus has transfer services allowing you to choose types of vehicles and their class.

Keep in mind that Amadeus car and transfer APIs belong to the enterprise suite of services meaning that you’ll have to negotiate their terms of use with Amadeus representatives directly.

Travelport API

Travelport XML API obtains data from several GDS inventories that Travelport represents: Galileo, Apollo, Worldspan, and Axess. These offer a range of content for car search and booking:
  • search for availability, images, details, and pricing

To check out the API, you can request test access for 30 days.
