The Taxonomy API exposes the Product Type (PT) taxonomy that Walmart uses to classify items. This API provides users with all Product Types (PTs) categorized into their respective Product Type Groups (PTGs), which are further organized into categories.
To retrieve the ProductType taxonomy, include the version
attribute in the query parameters as instructed below. This API also supports the older, category-based taxonomy. To continue using the older taxonomy, simply omit the version
attribute.
