Before publishing an item on Walmart.com, you need to specify the product details during Item Setup. This is called defining the attributes of an item.
After identifying the right category for your item(s), download the relevant template / XSD and proceed with the defining attributes step. Read through the item imagery guidelines and have the image URLs ready.

** Note: This article explains only the common attributes required for item setup. There will be compliance attributes and additional required attributes that should be identified and defined based on the category and type of item. **

To see a completed template, download the zip file at the bottom of the article Sample Item Setup Files.

Similarly, food products should have the attributes Has GMOs and GMO-Free Claim attributes defined.And, for certain products sold in California, you need to specify the Prop65Warning Text attribute.

Provide all of the relevant compliance attributes for your items in the Excel templates or XSD to meet the compliance requirements.

For example, clothing category items require additional details like Gender, Clothing Size, Color, Fabric Material Name, Fabric Care Instructions, Fabric Material Percentage, Occasion, etc. These attributes are important because they help Walmart.com categorize your items correctly.

Known Issues

• Current allowed Shipping Weight-Unit: The only identifier type allowed at the moment is LB. All other units like KG, G, MG, OZ, although specified in the Excel templates and the XSDs, are not allowed and will cause an error if ingested.
