Offers by EAN

StoreLinkr offers your products on the marketplace's existing catalog. The product is matched by EAN, so there are no categories or attributes to map. Products without an EAN are skipped.

Price updated

Stock updates

The marketplace decides on every application itself. Conditions can change, so check them with Happy Size before you apply.

How to connect Happy Size to StoreLinkr

You apply as a seller with Happy Size. Once approved, you create the API key in the seller back office.

Happy Size runs on Mirakl. In StoreLinkr you connect a marketplace, choose Mirakl and then Happy Size. StoreLinkr offers your products by EAN on the Happy Size catalog, accepts new orders automatically and sends the tracking code back once you ship.

Combine Happy Size with other marketplaces

Your stock stays central in StoreLinkr. If you also sell on other Mirakl marketplaces, bol or Kaufland next to Happy Size, every sale is reflected on all channels right away. That prevents overselling.

Why others use StoreLinkr

We are very satisfied with the data link between CycleSoftware and our website. It saves us a lot of time because we work with inventory management. Thanks to the connection, the stock in the webshop is always up to date.

Christian Schattevoet

The data link works great and fast, stock is immediately adjusted whether something is sold in the store or webshop. The time you save depends on how much you sell, but you do no more manual stock correction. The connection saves on double sales or ordering more quantities than in stock.

Aster de Nil, Fietsen Aster

We are satisfied with the link. It saves us at least 2 hours a week. When a bike is sold it is quickly taken off the internet, so no more people come for a bike that is already sold.

Hulstein Fietsen, Patrick
