One interface for three marketplaces — and less pain

In SellerHub, we built an abstract adapter layer for integrating with Ozon, Wildberries, and Yandex.Market. Because each marketplace has its own API, its own terminology, and its own limits — the usual story: as if three colleagues were doing the same task, but each one “their own way” 😅

What we did: — brought all APIs to a single interface; — introduced adapter versioning, so we can update the integration for one marketplace without side effects for the others; — added monitoring that automatically catches “broken” integrations if a marketplace suddenly changes its API.

Against the backdrop of the constant talk about API-first and unstable external integrations, this is really a must-have. When an external service decides to “just make a small update” on Friday evening, you want to avoid panicking and simply open the alert and calmly fix exactly the adapter that needs it.
