Introduction

The Flight GDN (Global Data Network) Seller API provides a unified integration point for accessing global airline content. It aggregates flight inventory from multiple Suppliers - such as airlines, B2B consolidators, and other authorized distributors - and supports a wide range of standards, including NDC, EDIFACT, and proprietary APIs.


By providing a single, simplified API, we enable Sellers to seamlessly connect to their preferred content sources, eliminate technical barriers, and reduce industry fragmentation. Our goal is to promote transparent and efficient commercial relationships between Suppliers and Sellers. 


This documentation will help you build and integrate with our API.



Version Control

This section indicates the published API versions. Additionally, each individual API will include a detailed record of its version history and changes.

Environment

DerbySoft provides two environments for Sellers: Test and Production (Prod).


The Test environment mirrors all functionality of Prod. However, that Test uses mock data intended only for API testing. This data is not representative of real-world values and may differ in volume from Prod.
