Walmart Fulfillment Services (WFS)
Our system automatically scans every Walmart template for errors. It checks for missing required attributes, incorrect data types, invalid check digits, copy-paste errors and more. This guide shows you how to find and address errors if your template fails the pre- or post-validation check.
Common upload errors
1. Invalid product ID
The error message could identify invalid Product ID for the selected Product Identifier and will tell you which row has the error.
What should I do?
Correct the error in the file then save the file and upload it back in Seller Center. Check out Troubleshoot Product ID Errors to learn more.
2. Missing attribute metadata
The error message could identify missing attribute metadata.
What should I do?
You should download a new spreadsheet if you are not sure what was deleted/altered. Make sure not to delete any data in Row 1-6. If you added multi-select attributes, make sure that all the information in rows 4-6 were copied and pasted into the new columns. Check out this guide to learn more about multi-select attributes.
3. Error file
If you encounter an error while uploading an item setup spreadsheet, an Upload error message will automatically download the file. In this error report, you can easily identify the number of errors and their descriptions in columns A and B. All cells that contain errors which need to be fixed will be highlighted.
What should I do?
Correct the errors in the highlighted cells, then re-upload the template when finished. Once your upload completes, navigate to the Activity Feed dashboard to confirm the template processed successfully. Review this guide if the error relates to an invalid product ID.
Before uploading your template, double-check that you’ve filled out all of the required attributes, that they are within the character limit and that attributes with closed-list options have been properly selected.
Common post-upload errors
1. Main Image URL does not meet our image URL requirements
What should I do?
Review this guide to view our image URL requirements and update your content accordingly. You can make updates within the report or within the Full Item Setup template. Then, re-upload the document into Seller Center and check the Activity Feed to make sure your errors are resolved.
2. You are not authorized to set up ‘CUSTOM’ Product IDs for UPC exemptions
What should I do?
Find the correct product ID for your item. If you sell products that don’t have a product ID (e.g., private label or handmade jewelry), you can request a UPC or GTIN exemption to sell these items on Walmart.com. To request an exemption, select the Help button in the Seller Center menu bar to contact Support.
If the item you want to sell is something you’ve manufactured or produced, you may have to purchase a product ID. You may choose to purchase a GTIN, UPC or EAN from GS1 here. If you choose to purchase an ISBN, consult the appropriate authority by country through using the ISBN lookup tool.
3. The item must have a Variant Group ID, Variant Attribute Name, and 'Is Primary Variant' value to be set up correctly on the website
What should I do?
Update each appropriate column by following the requirements listed in this guide.
Common system errors
If there is a technical issue in our system, you may receive a feed error when setting up your item. Wait a day as our system automatically attempts to reprocess your submission every few hours. If we’re unable to process your submission, contact support in Seller Center by selecting the Help button in the menu bar. Be sure to include the Feed ID and the spreadsheet.
Walmart-fulfilled errors
1. Hazmat assessment is required
If we’ve identified your item as a potential hazardous material, we'll review it within three business days. To find out which items are considered hazmat, review Hazardous Materials Overview.
What should I do?
After three business days, you can check the status by going to the Items on Hold page. You can correct any items with an Action Needed status. If your item has been in review for more than three business days, contact Seller Support.
2. Package dimension information is incorrect
Your item must include information about its depth, width, height and weight.
What should I do?
Include measurements for your item or confirm they’re correct. You'll also need measurements for at least two levels of trade item hierarchy (each/inner pack/case/pallet).
3. PackConfig does not match sellable GTIN
The product ID in the category tab must match one of the GTINs in the trade item hierarchy (each/inner pack/case/pallet).
What should I do?
Trade item hierarchy describes how your item is shipped to a WFS fulfillment center and how it’ll ultimately be shipped to customers. In the trade item configurations tab, make sure either each inner pack, case or pallet GTIN matches the product ID from the category tab. For example: if you sell an item in bulk as a case, then the product ID in the first tab should be the same as the case GTIN in the second tab. Review WFS Trade Item Configuration for more detail and examples.
