Update: Expanded guidance for item variants

Date: June 24, 2026

We've updated the Setting up multiple variants of an item guide to provide more comprehensive guidance on creating and managing variant groups through item setup and maintenance feeds.

What changed

The updated guide now includes:

• An overview of how variant groups work and when to use them
• Detailed explanations of variant group attributes, including variantGroupId, isPrimaryVariant, variantAttributeNames, and swatchImages
• Guidance on selecting and managing primary variants
• Information about supported variant attributes
• Examples for both single-attribute and multiple-attribute variant groups
• Best practices for creating and maintaining variant groups
• Instructions for viewing existing variant groups using Item Management APIs
• Troubleshooting guidance for common variant grouping issues

Why it matters

Variant groups help sellers present related products on a single Walmart item page, making it easier for customers to compare available options such as color, size, flavor, and other supported attributes.

The expanded documentation provides more complete guidance for sellers and solution providers using item setup and maintenance feeds to create, maintain, and validate variant groups. This can help reduce configuration errors and improve the customer shopping experience.
