TravelDistro Brings Payments-Grade Reliability to Travel APIs With HMAC Signing and Idempotency

TravelDistro brings the engineering principles of modern payment APIs—signed requests, idempotent retries, and a structured error catalogue—to the travel distribution sector in Türkiye.

Stable error codes, signed requests and idempotency are table stakes for payments — travel deserves the same reliability.”— Alper Tekin, Founder of Travel Distro

Today, TravelDistro revealed the developer experience underpinning its B2B travel API marketplace, adopting engineering techniques from contemporary payment systems for travel distribution throughout Türkiye.

TravelDistro functions as an API-first marketplace, making six travel verticals—tickets, tours, transfers, car rental, eSIM, and hotels—available via a single, versioned API. Every request is secured with HMAC-SHA256 signatures, and distinct keys per environment prevent credentials from crossing between sandbox and production.

To prevent duplicate bookings, the API supports idempotency keys, enabling integrators to safely retry any request after a network failure. Rather than returning blank HTTP 500 responses, TravelDistro provides a catalogue of stable, machine-readable error codes, each accompanied by a human-readable explanation and a retry suggestion.
"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 includes OpenAPI documentation and a sandbox that mirrors production inventory, allowing engineering teams to build and test booking workflows using simulated data before requesting live keys. Endpoints follow a predictable pattern such as /v1/tickets, /v1/tours, /v1/transfers, /v1/rental-cars, /v1/esim, and /v1/hotels.

Multi-currency capabilities cover Turkish Lira, US Dollar, Euro, and British Pound, and API content is available in English, Turkish, Persian, and Spanish, cutting down localization work for agencies serving travelers arriving in Türkiye.

TravelDistro is run by a technology group that operates software and data companies in Edirne and Dubai, in addition to tour and transfer services built on the same infrastructure.
