Tradeinn Shopify Integration — sync orders, inventory and pricing

Spanish sports and outdoor retailer shipping worldwide from Girona, with a Mirakl marketplace spanning diving, cycling, running, fitness and outdoor gear. Sellintu handles catalogue, offers, orders and returns from Shopify.

Selling on the Tradeinn marketplace

Tradeinn is Spain's largest online sports retailer — a family of specialist shops (bikeinn, trekkinn, swiminn, snowinn, diveinn, smashinn and more, each dedicated to one sport) that together ship to customers in over 190 countries. Its marketplace, running on Mirakl, lets external sellers list into those specialist storefronts.

The structure is the opportunity: your cycling range lists where every visitor is a cyclist, your dive gear where every visitor dives. Few marketplaces deliver audience relevance that precisely — and Tradeinn's international shipping footprint means one integration reaches buyers far beyond Spain.

What you need as a seller

An EU-invoicing business, EAN-coded products in the sports and outdoor categories, and fulfilment that can meet Tradeinn's delivery promises — which vary by destination given the group's global reach. Listings benefit from multi-language data (Tradeinn's shops run in many languages), though English and Spanish carry most volume. Commission is per-category and contractual; no public rate card.

What Sellintu syncs

One connector from Shopify to Tradeinn's Mirakl backend. Sellintu maps your products to the right specialist shop's category tree — a triathlon range can span bikeinn, swiminn and runnerinn from one Shopify catalogue — keeps stock synced continuously across all of them, and imports orders into Shopify with the destination and carrier data you need for international fulfilment. Price changes propagate without re-uploading anything.

Getting started

Apply to Tradeinn's seller programme, connect the approved Mirakl account to Sellintu, and map your catalogue once. Sports gear is EAN-disciplined, which makes the matching step faster here than in most categories.
