# Download schemas for Returns API

Schemas are formal definitions that specify your feed's structure, data types, and required fields. They help ensure your return-related data is correctly formatted before submission to Walmart.

A feed is a file containing structured data that details updates for one or more return actions, such as issuing refunds or updating return statuses. To learn more, refer to the [Walmart Feeds guide](/us-marketplace/docs/feeds-overview).

Walmart provides an official JSON schema to help you validate your Returns API feed structure:

**JSON schemas** (`ReturnOrderResponse.json`, `ReturnOverride.json`, and related files):\
[MPReturnsJsonSchema.zip](/image/asdp/us/mp/returns/MPReturnsJsonSchema.zip)

These files define the required fields, data types, and structure for return-related submissions. Use the schema to validate your JSON files before uploading them, ensuring they conform to Walmart's format.

> **Note**: Improperly formatted files can result in rejected submissions or failed refund processing.
