OTA Hub API - Hotel & Flight Booking API

Demircode OTA Hub API is a centralized booking and API management platform for the travel industry. It unifies multiple hotel and flight suppliers (GDS, Bedbank, airline API) under a single RESTful API layer, enabling B2C websites, B2B agency portals, and mobile apps to use the same search and booking infrastructure.

Why OTA Hub API?

In the travel industry, every supplier has a different API format, authentication method, and data structure. Amadeus is XML-based while Paximum uses JSON; Turkish Airlines implements its own SOAP protocol. OTA Hub API normalizes all these differences and presents a single standard JSON API to clients. With the codeless field mapping system, you can integrate a new supplier within days. Circuit breaker, health check, and fallback mechanisms ensure a faulty supplier doesn't affect the entire system; search results continue to flow from other suppliers.
