What is Shopify + OnBuy Integration?

Koongo connects your Shopify store to OnBuy via a direct API integration - automatically syncing your product listings, pricing, and inventory to a competitive UK marketplace with millions of buyers across multiple categories, operating with no listing fees and a direct payment model. The OnBuy Integration Wizard guides you through the full setup step by step - no coding required. Once your products are live, OnBuy orders are automatically imported into your Shopify store and inventory updates accordingly, so you manage everything from listings to sales in one place. For Shopify merchants who are registered business entities, OnBuy's no-listing-fee model means you pay a commission only on completed sales - no upfront costs for getting your products in front of millions of UK buyers. Koongo handles the product and order data sync so your Shopify store stays the single source of truth.
