What is Custom Platform + Amazon Integration?

Koongo connects your Custom Platform to Amazon via API, automating the distribution of product listings, pricing, inventory, images, and category-specific attributes to every Amazon marketplace you activate. Whether your store runs on a proprietary system, a headless setup, or a specialized platform, Koongo provides the integration layer to reach Amazon without rebuilding your stack. The Amazon Integration Wizard guides you through each step of the connection setup - no custom development required from your side. Once your products are live, Amazon orders are imported back into your system automatically, and inventory adjusts accordingly. You get a reliable data loop between your store and Amazon. Amazon's listing requirements include product identifiers, category-specific attributes, compliant images, and correct variant structures. Koongo's Rules Editor lets you configure the transformation logic that maps your store's product data to what Amazon actually accepts - so listings go live correctly rather than being rejected.

Key Benefits:

What gets your listings rejected on Amazon - and how to fix it

Missing product identifier Amazon requires a valid EAN or UPC code for most products to match your listing to an existing ASIN. Without it, your product cannot go live. Koongo's Rules Editor helps you map your identifier fields correctly before the feed is submitted.

Incomplete category-specific attributes Every Amazon category has its own required fields - watches need Display Type, jewelry needs Metal Composition, apparel needs structured size and color variants. Generic product data that works in your store often falls short of what Amazon's validation requires.

Non-compliant images Amazon requires product images of at least 1000px on the longest side, on a pure white background. Images that don't meet this spec are rejected at submission - before buyers ever see them.

Incorrect variation structure Products with multiple sizes or colors must follow Amazon's parent-child SKU structure. A flat product list that works in your store won't display correctly on Amazon without the right variation hierarchy in place.
