Which parameters are required in universal event tracking for dynamic remarketing in audience ads?

For dynamic remarketing in Audience Ads, Universal Event Tracking (UET) requires specific parameters to identify products and user actions. The Product ID is crucial because it uniquely identifies the product being viewed or interacted with, allowing the system to show relevant ads for that specific item. The Page type parameter tells the system what kind of page the user is on (e.g., product page, cart page, purchase confirmation), which is essential for segmenting audiences and triggering appropriate remarketing strategies. While "Product name" and "Page name" might be useful for reporting, they are not the required parameters for the core functionality of dynamic remarketing, which relies on the structured identification provided by Product ID and Page type.
