Download inventory schemas

Schemas are formal definitions that specify your feed's structure, data types, and required fields, ensuring that your file is correctly formatted before submission.

A feed is a file containing structured data that details inventory updates for multiple SKUs. To learn more, refer to the Walmart Feeds guide.

Walmart provides official schemas (XSD for XML, JSON schema files for JSON) to help you validate your inventory feed structure:

• XML schemas (Inventory.xsd, InventoryFeed.xsd, InventoryHeader.xsd):
  Inventory Management.zip
• JSON schemas (Inventory.json, InventoryFeed.json, WfsInventory.json, InventoryHeader.json):
  InventoryJSONSchema.zip

These files define the fields, data types, and nesting requirements. Before uploading your feed, use the schemas to validate that your file conforms to Walmart's requirements.

Note: Improperly formatted feeds can result in failed submissions or partial updates.
