Colissimo, twice
PrestaShop and Shopify, at Common-Services then Kosmonaft.dev
- Problem
- Merchants wanted La Poste pickup points inside their checkout, printable labels in their back office and tracking their customers could read — on two platforms that agree on nothing.
- Constraint
- One carrier API, two very different extension models: a PrestaShop module runs inside the shop, a Shopify app runs outside it and may only ask politely.
- What I built
- A shared understanding of the carrier domain — points, labels, tracking, returns — mapped twice onto the platforms. The PrestaShop side became Colissimo Max and Relais Max.
