Best Travel APIs to Help You Build a Great Product

Today’s travelers want to book flights, hotels, and car services on one platform, not a dozen. Stratos report proves that an estimated 700 million people will make a booking online by 2023. Apart from this, there are over 148 million travel bookings made annually.

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 the most useful flight, hotel, and car booking APIs.

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. Let's delve deeper into what API is: API (Application Programming Interface) is a special interface that developers can use. The main purpose of using an API is to implement the functions of a third-party application into your own product.

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

Next, we’re taking a look at the most popular travel APIs. By the main categories:

Hotels booking APIs

Such solutions are GDSs (Global Distribution Systems), connectivity vendors, and switches. The term of GDS refer to the global reservation systems for travel services. Using them, customers can use them to buy a flight ticket, order a transfer, and choose a hotel. In our case, we are talking about the last case. Сonnectivity vendors and switches are the scale aggregators that link hotel reservations, spots that are ready for booking, and details from a diversity of channels. They operate well both directly with hotels as well as with intermediaries. A switch is a subtype that links hotel CRS and providers and becomes a point of access for each aforementioned party.

Cars rental APIs

With car rental APIs, software engineers can design the utter solution to ensure the business’s customers with the most relevant offers from the most demanded worldwide car rental agencies, companies, and tour operators.

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

The key function of travel APIs is data transferring across travel agencies. Travel APIs enable travel agencies to get the most recent data about flights, bookings in hotels, car rentals, and even more, extracting them from a broad list of providers. It raises usability, value, and engagement in your travel platform as well as allows presenting the most relevant available flight or hotel variants to the audience. Having a wide spectrum of options to choose from, you are able to gain competitiveness and demand.

What's more, there are some more advantages and opportunities travel APIs bring:

No standalone availability management and control

Online Travel Agencies (OTAs) ensure APIs that software engineers can apply to extend the solution with flight booking details, available apartments, or any other useful travel data. Therefore, separate travel agencies are free of management and maintenance of their own travel assets. This also makes it easier for self-serving and making individual bookings for customers.

Maximum client attraction and retention

Surfing your solution and striving to find the best option for a flight or hotel reservation, APIs enable retaining customers without a need to redirect them to external travel software. API integrations guarantee that your travel agent withdraws all of the customer payments using secure payment gateways. This makes your website reliable for all of the parties engaged in this process.

Accelerated integration, seamless customer journey

Travel APIs can be added smoothly to the existing travel website or app and have perfect compatibility with external solutions. It enables travel agencies to implement any existing types of APIs available on the market with no influence on the functional flow. Developers are able to integrate the API rapidly, which is a way to advance the functionality at a decreased time-to-market.

These are the core advantages that your company can obtain from travel API integration. To summarize, we’d like to highlight that the most vital advantage of working with API is that it saves time when developing your own services. The developer gets ready-to-use solutions from travel agencies and does not need to spend time designing code for features that have already been implemented for a long time.Why is this important?

• The API can take into account nuances that a third-party developer may not consider or simply not know,
• The APIs give applications a certain consistency and predictability - the same function with the help of the APIs can be implemented in different applications so that it will be clear and familiar to all users.
• The API gives third-party developers access to closed services
• All you need to do is select the best travel API provider for your business. Here are some points that you may consider while choosing a travel API service provider for your business.

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.
