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.
