Updated 13 Nov 2022

Today’s travelers want to book flights, hotels, and car services on one platform, not a dozen. TrekkSoft’s report proves that: in 2018, the number of direct website bookings fell to 66.7%. While bookings made through agents increased from 17.5% to 24.3%.

In turn, travel platforms started to adapt their user experience. They've become more open to sharing their tools, and travel APIs seem to be the best means for that.

In this article, we're explaining what is travel API, how it works, and list 15 most useful flight, hotel, and car booking APIs.

What Is Travel API and How It Works

Previously, if a travel company wanted to expand their business onilne, they had to go for software development services. And build the tech solution from scratch or buy it from another company.

Today, we have travel booking APIs. They fetch and process data collected by CRM systems and allow developers to connect to this data. It's a kind of a control panel for linking with software components without dealing with the code itself.

Companies license third-party software products through travel APIs. It is a more efficient and quicker way compared to building software components from scratch.

How exactly does travel API integration work?

Let’s take TripAdvisor as an example. It's not just a travel content website now but a platform that allows visitors to read reviews, check prices, and book services, all in one place.

TripAdvisor has over 200 million reviews and is a trusted source for millions of travelers. It works with hotels, eateries, and attractions collecting the main content details (location, name, address, prices) and updating them in real time.

Here’s how hotel booking engine API helps them. TripAdvisor’s partners like online travel agencies, hotel chains, or individual hoteliers provide the platform with their pricing.

So when a user enters booking dates into the search field, TripAdvisor makes a call on the API of a trading partner. In turn, the partner automatically gives the relevant price.

Some suppliers provide hotel search API that allows using their services directly. If there's an integrated API of a payment gateway, travelers make secure payments using their credit or debit card or e-wallet.

Main benefits travel APIs bring:

  • Allow adding markups for end-customers
  • Charge users directly
  • Less content maintenance, more focus on core tasks (like marketing)
  • Reduce travel agencies overhead cost

Booking APIs become better and easier to use by both third-parties and customers. That’s why more and more partners work directly with brands. It’s a way to reduce the need for traditional tracking methods via affiliate networks and tracking providers.
