Creating Walmart Items via Unified

October 11, 2025

Unified allows you to create structured product listings on Walmart Marketplace via our Unified data model commerce_item. This guide explains the critical fields you must understand and provide correctly:

🧩 Key Concepts

🧠 How Metadata Works

Each type (subcategory) has a corresponding schema of fields allowed by Walmart. For example:

• animal_accessories allows fields like animalType, petSize, isFoldable, colorCategory, etc.
• computers allows fields like processorType, screenSize, ramMemory, operatingSystem, etc.

List the metadata fields from Unified using this API

NOTE: If item creation fails or takes too long to process, the feed ID and any error details will be returned in the error response.

⚠️ Important Note on Reading commerce_item Data via Walmart's GET and LIST APIs

When using Walmart's GET or LIST endpoints to retrieve commerce_item records (i.e., your catalog items), you will only receive a subset of the full item. This limitation is imposed by Walmart's public Marketplace APIs and is not configurable.

What's Missing?

• Fields defined in the Visible section of your original item feed (e.g., animalLifestage, assembledProductWeight, features, fabricContent, etc.) will not be returned in full.
• Walmart truncates or omits many category-specific structured attributes.

Why This Happens:

Walmart's GET/LIST endpoints are designed for high-level overviews or simple listing needs, not for reconstructing detailed item payloads. They surface:

• Basic identifiers (e.g., SKU, productName)
• Core logistics info (e.g., price, inventory, brand)
• A limited set of visible attributes
