Farelogix Gateway XML API
Developer Program

Airlines using parts of or the entire Farelogix Airline Commerce Gateway platform—including the Farelogix Open Connect—are able to offer travel agencies and other third parties access to the airline’s full suite of content through an industry standard XML Application Programming Interface, or API. The FLX NDC API provides a robust delivery vehicle by which users are able to make and manage bookings and reservations—including merchandising and other dynamic offers—out of the Airline Reservation System.

Companies seeking to access airline content via the FLX NDC API are invited to participate in the Farelogix Third Party XML API Developer Program. This program provides information, technical access, and support to facilitate development to the FLX XML Application Programming Interface (API).

In order to access airline content via our NDC API, you are required to have approval from one or more of our participating airlines. Once a carrier has approved you, initial enrollment requests will be handled by our ProServices department.
