NDC Community APIs

NDC (New Distribution Capability) is a travel industry-supported program launched by IATA (International Air Transport Association) for the development and market adoption of a new XML-based business messaging standard. The NDC Standard will enhance the capability of exchanges between airlines and sellers, while supporting personalization of the offers airlines can make and the way that air products are retailed.

More information about IATA’s NDC program can be found at http://www.iata.org/whatwedo/airline-distribution/ndc/pages/default.aspx

SITA are developing a series of APIs that will contribute to the advancement of this standard and facilitate the transformation and distribution of messages between business partners in the air travel industry,

There are currently two NDC APIs available as Proofs of Concept from SITA.

Messaging Hub API

This API transforms messages between NDC schema versions 1.1.3 and 15.2 to facilitate communications between NDC compliant air transport organizations. The POC platform currently provides transformation of NDC shopping and ordering requests in addition to response schemas.

Exchange API

This API is a consumer interface into a multitude of provider services using NDC versions 1.1.3 & 15.. It will initially support Baggage Charges, Baggage Allowance & Seat Availability services.

Note: This API is still in development and is only available for test on a retricted basis. For further details, please contact Mansour Rezaei-Mazinani@sita.aero.
