Overview

Amazon's Relationship Feed is a catalog management tool that allows sellers to define how products relate to one another within their listings. Whether you're connecting size and color variations under a single parent listing or linking accessories to a main product, understanding this feed schema is essential for organizing your catalog effectively and improving the customer shopping experience.

Key Points / What Sellers Need to Know

• Two relationship types exist — Amazon supports "Variation" relationships (parent-child listings) and "Accessory" relationships, each serving a distinct purpose in your catalog structure.
• Parent SKUs are not buyable — The parent item acts as a container that groups child variations together but has no price, quantity, or purchasable status of its own.
• Child SKUs are the actual products — Each child represents a specific combination of attributes (like size and color) and is the item customers add to their cart.
• Category-specific rules apply — Not all categories support variations, and each category that does may have unique requirements for how relationships are structured.
• The Relationship Feed only links items — It does not create the products themselves. You must first upload your Product Feed before submitting the Relationship Feed.

How Variation Relationships Work

Variation relationships are the most widely used product relationship type on Amazon. They allow sellers to group multiple versions of the same product under a single listing, letting customers toggle between options such as size, color, or style without leaving the page. The parent SKU serves as the umbrella listing and must be designated with a "parent" Parentage value in your Product Feed. You also need to define a Variation Theme on the parent — this tells Amazon which attributes (like Size or Color) will differentiate the child items. Each child SKU is then tagged as "child" with the same Variation Theme, and its specific attribute values are set in the Product Feed. Once all SKUs are uploaded via the Product Feed, you submit the Relationship Feed to formally establish the parent-child connections.
