More people are booking their entire trip online than ever before, with 83% of U.S. travelers booking travel online, nearly 150 million travel bookings made worldwide online each year, and an estimated 700 million people booking hotel accommodations online by 2023. 

With this level of demand for online travel booking, travel companies are well aware of the need to integrate into the digital ecosystem that the online travel industry has evolved into. This is an ecosystem in which hotels, airlines, auto rental agencies, and all-in-one booking platforms share information. And to enable this ecosystem, businesses must utilize travel APIs. 

I. What is Travel API?  

The travel API is a collection of web services that provide access to travel content from various sources, such as GDS, consolidators, wholesalers, and direct connect. Furthermore, the goal is to provide customers with an excellent booking and reservations experience by presenting them with the best travel options. 

The APIs of travel aggregators consist of flight reservation APIs, hotel APIs, and vehicle rental APIs, among others.

Travel API integration process

1. Supplier selection 

This will be the initial phase. When selecting a supplier, conduct exhaustive research to ensure that you select the best supplier for your travel agency based on availability, your region, your rates, their requirements, etc. 

One supplier may have a larger selection of hotels and better rates in your region than another, so it is prudent to verify their rates and availability in advance. Moreover, conduct your investigation, as not all suppliers offer multiple travel API modules (e.g., hotels, air, activities, etc.). 

2. Signing the contract & API documentation 

Once you’ve decided on a supplier, you must execute a travel API agreement with them. As stated previously, a provider may offer multiple APIs for various modules. Also, you will need a comprehensive contract encompassing all selected modules, with separate APIs as needed.  

You may also be required to make a retainer. However, if you have a strong relationship with the supplier and have purchased in large quantities, the travel API fee may be reduced or even waived. 

The supplier will send you and your technology provider an API document and test access once the contracting process is complete. Furthermore, the API documentation contains all technical information regarding the API and its components, such as its parameters, regulations, and services. Besides, this is where a dependable and trustworthy technology partner comes into play. 

3. API document assessment and development 

After the travel API documentation is complete, your technology collaborator will evaluate the API’s technical viability for their booking engine. This allows them to determine if the travel API is ready for deployment, if their XML connector requires modifications, or if they need to construct an entirely new connector. 

If you have multiple APIs, your technology partner will need to develop numerous connectors. 

4. Certification and integration 

Once the documentation and connector are complete, you must have it certified by the supplier. Moreover, existing connections typically require a couple of weeks to complete certification, while new connections require approximately one month. 

Once certification is complete, the provider will provide you with credentials to access their live feeds, which can then be used to make reservations. Furthermore, our technology partner will then replace the test feeds with the live feeds and integrate them into the booking engine. 

5. Post integration 

Once the integration is complete and your site goes live, clients/visitors will begin to see real-time data for the integrated modules. After the integration of travel APIs, the search response time is a common concern for many travel agents. 

The search response speed depends on various factors, including the booking engine’s architecture, the server’s location, the number of integrated APIs, and more. However, the most important factor is the supplier’s response time. Some suppliers take longer than others to respond. 

The average response time from the supplier is 10-12 seconds. As a result, when selecting a supplier, you must balance speed and cost, as many suppliers with competitive prices offer slow response time and vice versa. 

Therefore, it is essential to discuss speed concerns with your technology partner. Besides considering to choose Travel XML APIs, you can explore another travel solutions of progressive web app.

V. Tips to Consider When Choosing The Right Travel API Service Provider

2. Contract & API documentation 

Ensure that the service provider provides API documentation. If it fails to provide documentation, implementing an API can take several months. Furthermore, you must sign an API contract to begin. Besides, the API documentation includes parameters, constraints, and service descriptions. 

3. Post-integration services 

Upon completion of the travel API integration, your customers must be able to view the real-time availability of flights and hotels, along with the associated pricing information. Thus, if you encounter any technical issues, your service provider should resolve them as quickly as possible.
