Item spec: versioning and diff reporting

You can download item specification requirements for various feed types. The table below provides links to download the complete item spec requirements for 6,700 product types simultaneously. You can access both the latest and previous versions of the specifications to quickly compare which version you've integrated with and troubleshoot any issues on your end.

Use the Report Type column to review changes from the previous version of the spec to the latest recommended version. The diff report excludes versions that are not recommended. Walmart provides diff reports with each update to the item spec. Make sure to check this section regularly to capture all changes in item setup requirements. For example, the 4.X to 5.X Diff Report explains the changes between versions 4.X and 5.X, simplifying the 5.X migration process.
