Sell From Custom Platform To Guenstiger - No Custom Build Needed

What is Custom Platform + Guenstiger Integration?

Whatever system runs your Custom Platform store, Koongo turns your product data into a feed built for Guenstiger, without you writing a custom connector. Titles, pricing, images, and stock convert automatically into the CSV or XML format Guenstiger requires. Guenstiger works from a submitted feed rather than a live API, so Koongo's feed manager creates and maintains that file - including GTIN or EAN and VAT-inclusive pricing - using predefined templates that work for any custom-built system. Guenstiger only accepts registered businesses in Germany or the EU with valid VAT. Koongo helps your Custom Platform data meet that bar, opening access to millions of high-intent buyers regardless of what platform runs your store behind the scenes.
