API Diatome

Diatome API is a modular solution that enables brands to integrate a suite of circular operations — resale, trade‑in, and redistribution — directly into their e‑commerce infrastructure.

Easy to test, ready to integrate

Tested and documented on Postman since 2025, the Diatome API forms the technical foundation of the current Shopify app.

Diatome already manages all the core workflows of circular resale:
1) Creating and updating secondhand product listings in your catalog,
2) Managing orders, payments, and customer credits (gift cards, store vouchers),
3) Syncing logistics and your back‑office systems.

Every endpoint is documented and ready to use, allowing your developers to build, test, and extend their own connectors.

Multiplatform by design

The Diatome API is built on an interoperable, scalable architecture.
Its design allows each merchant to:
1) Connect Diatome to any e‑commerce platform (Salesforce, Prestashop, Magento, WooCommerce, etc.),
2) Automate circular workflows (resale, trade‑in, revaluation),
3) Customize front‑end experiences while maintaining a seamless journey between new and secondhand products — across web, mobile, and POS environments

Built for the commerce of tomorrow

E‑commerce is shifting toward API‑driven ecosystems, where intelligent agents capable of searching, comparing, and purchasing on behalf of users will automate buying and resale interactions.
In this new context, brands have every reason to regain control of their own secondhand market. Today, much of this value escapes them — yet it represents a tremendous economic, ecological, and community opportunity.
That’s the ambition behind Diatome API: giving brands the tools to manage the entire lifecycle of their products — well beyond the first sale.
