TravelDistro applies modern payments-API engineering — signed requests, idempotent retries and a real error catalogue — to travel distribution in Türkiye.

Stable error codes, signed requests and idempotency are table stakes for payments — travel deserves the same reliability.”

ISTANBUL, TURKEY, August 23, 2026 /EINPresswire.com/ -- TravelDistro today detailed the developer experience behind its B2B travel API marketplace, applying engineering practices from modern payments platforms to travel distribution across Türkiye.

TravelDistro is an API-first marketplace that exposes six travel verticals — tickets, tours, transfers, car rental, eSIM and hotels — through one unified, versioned API. Every request is authenticated with HMAC-SHA256 signatures, with separate keys per environment, so credentials never cross between sandbox and production.

To eliminate double bookings, the API accepts idempotency keys that let integrators safely retry any request after a network failure. Instead of blank HTTP 500 responses, TravelDistro returns a catalogue of stable, machine-readable error codes, each paired with a human explanation and a retry hint.
"Developers should never have to guess what a travel API just did," said Alper Tekin, founder of TravelDistro. "Stable error codes, signed requests and idempotency are table stakes for payments — travel deserves the same reliability."

The platform ships with OpenAPI documentation and a sandbox that mirrors production inventory, allowing engineering teams to build and validate booking flows against simulated data before requesting live keys. Endpoints follow a predictable structure such as /v1/tickets, /v1/tours, /v1/transfers, /v1/rental-cars, /v1/esim and /v1/hotels.

Multi-currency support covers Turkish Lira, US Dollar, Euro and British Pound, and API content is available in English, Turkish, Persian and Spanish, reducing localization work for agencies serving inbound travelers to Türkiye.

TravelDistro is operated by a technology group with software and data companies in Edirne and Dubai, alongside tour and transfer operations built on the same infrastructure.
