What is Custom Platform + Ebay Integration?

Koongo connects your Custom Platform to Ebay via API, syncing product listings, inventory, and pricing to the Ebay country sites you choose - eBay.com, eBay.co.uk, eBay.de, eBay.it, eBay.fr, eBay.com.au, and others. Whether your store runs on a proprietary system, a headless setup, or a specialized platform, Koongo provides the integration layer that connects your product data to Ebay's requirements per country site. The Ebay Integration Wizard handles the setup step by step - no custom development required from your side. Product configuration, variation mapping, order synchronization, and data submission are all covered through the wizard. The built-in health report flags item specifics gaps and listing errors before they affect your account. Ebay orders are automatically imported back into your order management system once the integration is live. Koongo also offers predefined templates that simplify setup for custom store environments. The Rules Editor lets you map your store's product data to Ebay's parent-child variation structure, populate item specifics per category and country site, include GTIN codes for branded listings, and set per-market pricing rules - all running automatically after configuration.

Key Benefits:

What gets your listings rejected or down-ranked on eBay - and how to fix it

Variation structure mismatches eBay uses a multi-attribute parent-child SKU structure for products with size, color, or other options. Most store platforms don't produce this format natively, so variation listings are the most common failure point. Koongo's Rules Editor maps your variants into eBay's required structure before they publish.

Incomplete item specifics Every eBay category on every country site has its own required item specifics - structured attribute fields. Listings with missing or incorrect values get down-ranked or rejected. Koongo's Rules Editor maps your product attributes to each category's item specifics, with transforms where your data needs reshaping.

Missing product identifiers eBay requires a GTIN (EAN or UPC) for listings in branded categories. Without it, products can't go live in those categories. Koongo helps you map identifier fields correctly so branded listings pass eBay's validation.

Country site differences eBay.com, eBay.co.uk, eBay.de, and other sites each run separate category trees, currencies, and requirements. A listing built for one site won't transfer cleanly to another. Koongo configures each eBay site as its own connection so your data is correct per market.
