The Taxonomy API methods enable you to assist both buyers and sellers by:

  • Helping sellers to determine the best eBay category under which to offer each inventory item for sale in a selected eBay marketplace. It helps sellers to select the categories of items to include in a campaign or promotion. It also provides information about the aspects to include when defining an inventory item in a given category.
  • Helping buyers to determine the appropriate categories in which to browse or search for the items they're looking to purchase in a particular eBay marketplace. For more information, see the Buying Integration Guide.

Note: Refer to the Taxonomy API overview page for more information about how the Taxonomy API can be used for both buyers and sellers.
