get https://marketplace.walmartapis.com/v3/items
This API endpoint allows you to retrieve a complete list of items from a partner’s catalog, supporting pagination through nextCursor or offset and limit parameters. Each item response includes an isDuplicate field to indicate whether an item is a duplicate. You can optionally include the showDuplicateItemInfo parameter to receive additional details about duplicate items, such as a destinationItem property that provides relevant information.
Throttling:
This endpoint is throttled at a maximum of 300 transactions per minute (TPM) per seller. When called with the showDuplicateItemInfo parameter, this is reduced to 60 TPM. For more details on throttling, refer to the Walmart throttling documentation.
