TravelDistro is adopting payment-API best practices—signed requests, idempotent retries, and a structured error catalog—for the travel distribution industry in Türkiye.

“Consistent error codes, authenticated requests, and idempotency are fundamental in payments—travel should have the same level of reliability.”— Alper Tekin, Founder of Travel Distro

TravelDistro has disclosed the technical details of its B2B travel API marketplace, using engineering techniques borrowed from modern payment systems for travel distribution throughout Türkiye.

TravelDistro functions as an API-oriented marketplace, offering six travel categories—tickets, tours, transfers, car rentals, eSIM, and hotels—via a single, versioned API. Each request is verified using HMAC-SHA256 signatures, with distinct keys for each environment, ensuring that credentials remain isolated between sandbox and production.

To prevent duplicate bookings, the API supports idempotency keys, allowing integrators to safely resend any request following a network outage. Rather than returning generic HTTP 500 errors, TravelDistro provides a set of consistent, machine-readable error codes, each accompanied by a human-readable description and a retry recommendation.
"Developers should never be left guessing about what a travel API did," said Alper Tekin, founder of TravelDistro. "Consistent error codes, authenticated requests, and idempotency are essential in payments—travel should have the same level of reliability."

The platform includes OpenAPI documentation and a sandbox environment that replicates live inventory, enabling development teams to create and test booking workflows using simulated data before obtaining production credentials. Endpoints are consistently organized, for example /v1/tickets, /v1/tours, /v1/transfers, /v1/rental-cars, /v1/esim, and /v1/hotels.

Multiple currencies are supported, including Turkish Lira, US Dollar, Euro, and British Pound. API content is offered in English, Turkish, Persian, and Spanish, cutting down on localization efforts for agencies that cater to tourists visiting Türkiye.

TravelDistro is run by a technology group that owns software and data firms in Edirne and Dubai, as well as tour and transfer services that run on the same underlying system.
