1. Set up conversion tracking for the specific standard events and their parameter object properties listed below.
The content_type object property's value must be set to either product, or product_group, depending on how you will configure your data feed when you set up your product catalog in the Catalog Manager.
If you will be tracking events associated with individual products, set the value to product. If you are tracking events associated with product groups, set it to product_group instead.
If you are using the content_ids property in your parameter object, its value should correspond to the product ID or product IDs associated with the action. IDs must match the IDs found in your product catalog. Values can be either single IDs, or an array of IDs.
If you are using the contents property in your parameter object, you must include the id property in a sub-object, with the product ID or product IDs as its value. IDs must match the IDs found in your product catalog. Contents property values can be a single object or an array of objects.
