May 22nd, 2024 by LisaD_Amazon
The Catalog Items API v2022-04-01 includes a new includedData query parameter option called classifications, which replaces the deprecated MWS GetProductCategoriesForSKU and GetProductCategoriesForASIN operations. You can use classifications to browse the classification trees assigned to an ASIN.
This new parameter is available to sellers and vendors. The former MWS GetProductCategories was only available to sellers.
