Current market share by GDS for various bookings

How to access GDS software?

We prepare the adapters and expose these adapter interface(s) which can be consumed by partners based on business needs. Here we design more adapters and expose the APIs as Microservices so that RestAPI communication will be most easier to implement and consume the WSDL with inbuilt documentation for the Asp.Net Web API 2.2  with OAuth support and out security wrapper will take care of partner validations to access these API,  If partner need more APIs to  consume like Car, Hotel and Rail we have  token scope mechanism validated against whitelisted domains with partner integration id.

Typical Workflow


Based on business needs we are ready to assist and extend capabilities of enhancing GDS API to quickly consume by avoiding complex parsing segments in the Itinerary for various GDS Systems, design, and provide solutions for a dashboard in configuring settings for parsing various things for GDS System and policies for TMCs and Agents.
