What is Custom Platform + GulogGratis Integration?

Whatever system powers your Custom Platform store, Koongo connects it to GulogGratis without requiring a custom-built integration. Product titles, pricing, images, and stock convert automatically into the format GulogGratis requires, without a developer maintaining the connection over time. GulogGratis works from a submitted feed rather than a live API connection, so Koongo's feed manager creates and maintains that file for you, using predefined templates that simplify setup for any custom-built system, regardless of what powers it. GulogGratis is one of Denmark's most active marketplaces, with over 700,000 monthly listings. Koongo helps your Custom Platform data hit GulogGratis's format, opening access to Danish shoppers regardless of what system runs your store.
