Export your OpenCart 4 product catalogue as an n11 product XML: productSellerCode, title, description, category fullName, price, displayPrice, currencyType, images with order, Marka/Barkod attributes and stockItems. Prices are VAT inclusive and converted to the selected currency, and a special price is published as price with the original as displayPrice. The feed URL is guarded by a token, cached for a configurable number of hours and generated in batches so large catalogues do not exhaust memory.
