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.
