GDS Integration: How to Integrate GDS API with Other Platforms


Complete guide for GDS integration, how to leverage GDS API to streamline operation. Compare top GDS providers to select the best one for GDS API integration

More and more people are booking their trips online. In 2023, the online travel industry generated $667.55 billion in revenue. According to the Trends Global Survey, 80% of global travelers feel it’s important to book their trips entirely online, with Millennials (86%) and Gen Zers (83%) leading the charge. 

This shift is prompting travel businesses to optimize their online operations, and a key component in this effort is the travel API. Travel APIs are collections of web services that provide access to travel content from various sources, such as GDS, consolidators, wholesalers, and direct connections. 

And GDS integration is one of the most important among these travel APIs as it allows travel agents and booking sites to reserve airline seats, hotels, vehicle rentals, and other travel-related services. 

So, how do you integrate this powerful tool into your travel website? Here’s a complete guide. Now, let’s start with the basic.

I. What is GDS (Global Distribution System)

A global distribution system (GDS) connects reservation inventories into one computer-based network. It’s widely used in the tourism industry, mainly for airlines, hotels, and car rental companies. This way, travel agencies and online travel agencies can sell tickets for the same flight, hotel, or car rental. 

GDS in travel also acts as a middleman between vendors like hotels and airlines, and service providers like online travel agencies. While most big GDSs are linked to major travel agencies, smaller and cheaper GDSs might connect to fewer travel agencies. 

Travel businesses sign up and connect their inventory to a GDS integration. Once connected, users can use different portals associated with the GDS to buy from a vendor. This can prevent overbooking, also service providers can get real-time inventory updates from the airline or hotel. 

Besides, travel companies can show their inventory and automatically update products and rates. This lets them use dynamic pricing, which instantly updates across all their portals. 

Even with the rise of third-party online travel agencies (OTAs) like and Expedia, GDS systems are still the top way to promote your hotel to the corporate travel market and attract travelers globally.

IV. Step-by-Step Guide to Integrate GDS in Travel

GDS integration requires careful planning and execution. Here’s a breakdown of the key steps:


1. Choose the right GDS integration

Start by selecting the GDS that best fits your business needs. As we mentioned before, top GDS providers you can consider are Amadeus, Sabre, and Travelport. Each GDS has its own strengths, weaknesses, and coverage areas. Some may offer better inventory or rates for specific regions or segments, while others might provide more features like dynamic pricing, ancillary services, or rich content. Compare these options based on costs, benefits, and compatibility with your business model and target market.

2. Use a standard user interface

Next, use a standard interface to communicate with the GDS. A standard interface is a set of rules and protocols that ensure data is exchanged consistently and accurately between systems. The most common standard interface for GDS integration is the Open Travel Alliance (OTA) XML specification. OTA XML allows you to send and receive messages to and from the GDS using XML tags, facilitating requests for information such as availability, fares, booking, and ticketing.

3. Implement a middleware layer

The third step is Implementing a middleware layer between your platform and the GDS. This can simplify the integration process and enhance performance as the software component acts as a bridge, translating and validating data, caching and storing data to reduce requests, applying business logic to customize content and pricing, and managing the GDS connection for reliability and security.

4. Optimize user experience

Great user experience is important for converting and retaining customers. Remember to design an intuitive interface that makes it easy for users to search, compare, and book travel inventory from the GDS integration.  

Besides, you should provide accurate information, such as images, descriptions, ratings, and reviews, to help users make informed decisions. Then, offer flexible options like filters, sorting, payment methods, and cancellation policies to meet users’ needs.  

And don’t forget to ensure fast and reliable services, such as confirmation, notification, and support, to build user satisfaction and trust.

5. Update and maintain the GDS integration

Regular updates and maintenance enable you to keep your GDS integration functioning smoothly.  

That’s why you need to follow the latest standards and specifications of the GDS and the standard interface: 

– Test and debug the integration regularly to fix any issues and monitor its performance to optimize efficiency.  

– Seek feedback from users and partners to continually improve the quality and value of your platform.

V. If Not GDS, Then What? Exploring Alternatives

Generally, GDS integration serve two main purposes: 

– Helping travel agencies, OTAs, and TMCs cover all travel management needs. 

– Providing a primary source of inventory for air flight distribution. 

While GDS in travel is a great option for travel distribution, there are several other choices to keep in mind, depending on your requirements and specific goals. Here are some alternatives to consider:

1. Large OTAs

Expedia and are powerhouses in the travel industry. They can offer significant distribution support to smaller businesses while taking their own profit from it. 

– Expedia Group: With over 1 million properties across its subsidiaries, Expedia Partner Solutions and its REST-based Rapid API provide access to 700,000 global accommodations and 25 different property types. It also offers 29 million property images, 21 million room images, 82 million travel ratings, and 57 million reviews. User-generated content is updated daily and accessible via the API. 

– Listing over 2 million properties,’s affiliate program includes widgets, banners, search boxes, and more. Its Demand API supports XML and JSON formats, providing live rates, availability, hotel content, and booking processing capabilities. This API not only offers a wide variety of accommodations but also allows you to choose which options appear on your website and helps track your earnings.

2. Wholesalers

For many OTAs, wholesalers or bed banks are key sources of inventory. Major players like Hotelbeds offer high-level customer service, advanced APIs, large inventory, and market expansion opportunities. 

In this model, a wholesaler contracts with a hotel to sell a set number of rooms at a fixed price for a specific period. These rooms are then sold to OTAs and TMCs. Hotels and wholesalers aim to keep rooms filled and often negotiate special rates.

3. Direct connection to providers

Direct connectivity to transport and hospitality providers is another viable option. Typically available via two-way API communication, this method allows data exchange between different systems. By avoiding middlemen, OTAs get more relevant and updated content, resulting in more competitive pricing.
