All in one, one for all!

The XML API interface provides access to the full content of the Ypsilon booking engine.

One common source of content for all GDS, low-cost carriers, charters and consolidated net fares. The focus of data exchange is set on providing information for the flight booking process. In addition, information about completion of bookings is also provided. It provides access to the full GDS air content, consolidator Net fare, low-cost carrier content and charter flights.
Due to the fact that the Ypsilon XML Pro is based on officially standardized and modern technologies such as HTTPS and XML, it is extremely easy to implement.
Various knowledge sources can be found in the internet for the development of client applications.
The XML API offers content from all major GDS, over 180 low cost carriers supplied from different sources and suppliers, charters, web fares, direct connect fares and consolidator fares.
The API provides a full blown search and booking capability, from availability and pricing request to booking request.
The XML API is GDS independent and is offered as SaaS “software as a service”. It does not require any hardware on the customer side.
