Walmart is excited to announce that select Marketplace sellers will have an opportunity to capitalize on their shipping advantage and strong performance by participating in the Walmart Free 2-Day Shipping program beginning October 22, 2018.
See knowledge base article for more details on the program. Eligible sellers can setup their SKUs for participation in the program using bulk upload excel in Seller Center or item feed API.
Changes summary for MPOffer.xsd, MPCommons.xsd (v3.2). Refer to existing Item Feed API for details on parameters.
- Additional optional parameter "ShippingProgramOverrides" to specify states for 2-Day offer regions/ states.
- Additional optional parameter "fulfillmentLagTime" to specify lag time before shipping.
- Existing parameters "price", "ProductTaxCode", "ShippingWeight" are made optional for item updates only (processMode=REPLACE_ALL). These attributes are still required for item creation (processMode=CREATE). See Item Maintenance for more details on processMode.
Note that Fulfillment Lag Time should be specified only with Lag time feed. Inventory feed should no longer be used to specify lag time feed as this will be deprecated in an upcoming release.
