Flight API integration refers to the process of connecting and integrating a Flight API (Application Programming Interface) into a travel technology system, such as a travel website, mobile app, or booking engine. The Flight API allows the travel technology system to communicate with the airline's reservation system and retrieve real-time flight data, including flight schedules, availability, fares, seat maps, and other related information.

The integration involves establishing a connection between the travel technology system and the Flight API through the use of API keys and authentication protocols. Once the integration is in place, the travel technology system can send requests to the Flight API, and in return, receive the requested flight data in a standardized format, usually in XML or JSON.

By integrating Flight API into their systems, travel businesses can offer their customers a seamless and efficient flight booking experience. Users can search for flights, compare prices, view available seats, and make bookings directly within the travel technology platform, without the need to visit multiple airline websites. The Flight API integration ensures that the flight data presented to users is up-to-date, accurate, and consistent with the information provided by the airlines.
