An Overview of Travel and Booking APIs for Online Travel and Tourism Service Providers


Travel booking APIs are vital tools that enable travel agencies, businesses, DMCs, distribution platforms, and corporate intranets to provide excellent value and service to their customers. Customers can book everything online, including flights, hotels, transfers, excursions, and vacation packages.

Trawex has a team of brilliantly skilled professionals who have incredible insights and knowledge to build and create effective Travel API Integration solutions for your business, whether it is a Hotel Booking API, Travel API, Flight API, Sightseeing API, Cruise API, Activities API, and so on.


The main types of travel APIs and how do they work?


A travel API is a collection of web services that allow you to access travel deals from various travel consolidators. Travel APIs, such as flight APIs, car APIs, and hotel APIs, allow travel agencies, tour operators, and travel companies to access their rich content and travel deals.

Travel agents can integrate travel inventory from third-party GDSs, travel wholesalers, aggregators, consolidators, and others into their website's booking engine or travel portal. 

Travel agents can use the Travel API to gain access to various travel options and improve the functionality of their website.


Integration of APIs in the travel business allows travel agencies to avail of these benefits: 


  • A single booking platform for hotels, flights, and cars.

  • Real-time booking system.

  • A booking engine that is secure, reliable, and robust.

  • Several API Options.

  • Customize the interface to reflect your company’s highlights.

  • It is simple to incorporate travel search.


So, here are the most common APIs used to integrate travel industry features and data.


  • Flight search and booking by GDSs and OTAs

  • NDC integration for merchandising and rich content

  • Flight data, schedules, and fares

  • Direct hotel booking with PMSs and channel managers

  • Hotel booking with aggregators: GDSs, connectivity providers, and switches

  • Wholesale hotel booking with bed banks

  • Partner hotel booking with OTAs

  • Hotel mapping

  • Car rental booking

  • Business travel management and expense tracking

  • Reviews and ratings

  • Tours, attractions, and experiences

  • Public transportation


1. Flight search and booking APIs by GDSs and OTAs


Amadeus APIs


Amadeus APIs refer to GDS (global distribution system) functionality. The APIs are available as self-service or enterprise sets:


Self-Service APIs


Self-service APIs have replaced an old travel booking API — Innovation Sandbox — and are designed for both prototyping and commercial use. These APIs make it easier to search for flights and hotels, such as the cheapest dates, lowest fares, and most booked destinations.


Enterprise APIs


This is the main set, which includes nine different distribution types:


  • Railroads

  • Flights

  • Hotels

  • Car rentals

  • Transfers

  • Cruises

  • Travel insurance booking

  • Customer profiles

  • Utilities


Each type contains several APIs. Some provide information by locating the lowest fares or flexible-schedule fares. Others are tailored to ticket booking, providing ample flexibility in configuring the set of services for the client's product. Enterprise APIs are available in a range of REST/JSON and SOAP/XML formats. To inquire about pricing and API access, you must contact Amadeus directly.


Sabre flight APIs


Sabre GDS API Integration has transformed the travel industry. Sabre Flight APIs include seat and flight schedule availability, low-cost flights, price changes, and online ticketing. From shopping to booking flights, the Sabre Airline API has it all.

  • Sell more seats consistently

  • Make decisions with accurate data

  • Allow your business to run smoothly

  • Get real-time information on seat availability and price changes.

Google Flights API


Google Flights is a flight search and booking engine that assists in the acquisition of airline tickets from third-party suppliers. Customers can compare options and prices, as well as quickly find locations where they can purchase their tickets. Although this platform is available in 90 countries, it is primarily aimed at enterprise partners.

Google APIs are open, well-documented, and widely used across industries. Their API allows developers to access this data to search and compare airline flight prices.


Skyscanner Flight APIs


Skyscanner is a metasearch and travel agency that has 100 million monthly users who research and book tour packages such as flights, hotels, and car rentals. They compare thousands of routes and providers to help users find flights and tickets all over the world, allowing customers and businesses to take benefit of the best deals at all times.


There are two versions of the Skyscanner API:


The Airline Price Review API allows you to extract the best deals quotes from their cache prices. This allows you to create flexible searches. The disadvantage is that prices for less popular destinations are not updated very often. As a result, when the price changes, your users could not see the updated price.

The current flight prices API displays the exact fares at any time. However, customers should enter the exact time and route for each search. This is useful when comparing prices for specific dates, routes, or both.


Travelfusion API


Travelfusion is a flight and hotel aggregator that works with both low-cost and legacy airlines. The company actively supports the IATA NDC initiative and provides XML APIs to travel agencies and suppliers. You can search and book flights utilizing their inventory.

NDC is an IATA standard that requires airlines worldwide to provide direct connections to travel agencies and technology companies. These standards increase the effectiveness of communications between airlines and travel agents by providing full and rich airline content as well as providing a transparent shopping experience. For all fare types, travel agents can access ancillary content as well as the last available seat.


3. Flight data, schedules, and fares


Trawex design flight software helps travelers with timely notifications before a departure, tracks flight status, and alerts about delays. To provide such services, you must obtain detailed information about flights, connections, and weather. So, the final group of air travel APIs is all connectivity options that aid in the collection of technical and specific flight data.

4. Direct hotel booking with PMSs and channel managers


Direct connection via property management (PMS)- 


A PMS plays an important role in running the hotel’s operations smoothly. It allows hoteliers like you to manage day-to-day operations and complete all tasks more effectively and precisely. A hotel property management system allows users to easily manage, schedule, and organize all of their daily operations.

These solutions serve as the central database for all hoteliers. In a digital world, hotel property management systems (PMSs) allow you to manage all of your inventories, guest billing, reservation system, check-ins, housekeeping, and bookings.
