Faster item setup with enhanced Item Search API

You can now use the Item Search API to quickly determine whether Walmart already has the item you want to sell. With the Item Search API, you can check if an item already exists in Walmart’s catalog, choose between offer-only (MP_ITEM_MATCH) or full setup (MP_ITEM) and retrieve prefilled attributes using SPEC format (U.S. only). This update reduces your item setup time by helping you identify whether to use offer-only or full setup and by providing prefilled catalog attributes where available. Learn more

Update to Expected Ship Date calculations

We’ve updated the Expected Ship Date calculation for seller-fulfilled orders. If your fulfillment lag time settings are greater than zero, the order cutoff time will not be used to determine the Expected Ship Date. In this scenario, the Expected Ship Date will be calculated based on the order date, regardless of cutoff time, to help provide more consistent delivery promises to customers. This update may result in earlier Ship by dates. We suggest reviewing your lag time settings to ensure you can meet the updated expectations. Learn more
