If any supported optional fields are provided, we will treat them as a full
override when looking up product information from the catalog. Thus, it is
important to ensure that the overriding fields are accurate and
complete.
All other product fields are ignored and instead populated via catalog
lookup after event ingestion.
Quantity of the product associated with the user event.
For example, this field will be 2 if two products are added to the shopping

purchase-complete event types.
