Use this API endpoint to retrieve detailed information about a specific item from the partner catalog. Pass the item identifier (id) as a path parameter. By default, the identifier is treated as a SKU unless productIdType is specified.

The response includes isDuplicate, which is true if the item is a duplicate and false otherwise. This field is omitted when productIdType is SKU.

To include customer favorite status in the response, set includeCustomerFavoritesStatus=true. When included, the response returns isCustomerFavorite, which indicates whether the item is currently favored by customers.

For variant items, the response includes variantGroupId, which identifies the group the item belongs to. When available, variantGroupInfo includes:

• isPrimary: true if the item is the primary variant displayed in search results
• groupingAttributes: An array of name/value pairs that represent the item's variant attributes (for example, color: Blue or size: M)

These fields are omitted for non-variant items.
