Type that uses CriterionTypeEnum


Calls that use CriterionTypeEnum


Indicates the criterion for a rules-based campaign is based on a seller's inventory reference IDs. An inventory reference ID can be either a seller-defined SKU value or an inventoryItemGroupKey.

An inventoryItemGroupKey is a value used by the Inventory API to indicate a listing that's the parent of an inventory item group (a multi-variation listing, such as a listing for a shirt that's available in multiple sizes and colors). To fully identify a such a listing, you must specify both its inventory_reference_id plus its inventory_reference_type.
