The new Item spec v4 provides three sets of JSON schemas that you can use with the new feed types to represent an item object for either Marketplace item, Marketplace and WFS item, or Item maintenance. Select the JSON schema depending on whether you are creating new items for Walmart alone, Walmart and WFS, or you are maintaining items that are currently set up. Spec v4 is available in JSON schema format only for better ease of use.
Product Tax Code auto-assignment
Sellers do not need to specify product tax code attribute for Item spec 4 versions. Product tax codes are now auto-generated during the item setup process.
The new MP_ITEM_SPEC version 4.3 has updated variant attributes and removed Alcoholic Beverages, Weapons spec categories.
The MP_ITEM_MAINTENANCE spec version 4.3 still contains the
ProductTaxCode attribute so that sellers can optionally override a product tax code that was auto-assigned when the item was set up initially.
