Spartoo does not support EAN matching between sellers. This means your products cannot be linked to listings created by other marketplace sellers. You must provide complete product and offer data for all your products.
However, if your product’s EAN matches an item sold (or previously sold) directly by Spartoo itself, your offer will be automatically matched to Spartoo’s existing product listing. In this case, Spartoo will use its own product sheet, and your offer will benefit from the visibility of that existing listing.
Providing the EAN code is strongly recommended by Spartoo, but not mandatory.
