GA4 Ecom Attributor is a new open-source solution designed to enhance the monetization reports in GA4 by making them more actionable and insightful for ecommerce events such as 'add_to_cart' and 'purchase'. It temporarily stores and reads Item List and Promotion data throughout the checkout process.

Advertisers often face challenges in providing List and Promotion data with every ecommerce event due to website complexity. GA4 Ecom Attributor addresses this by storing List and Promotion information each time a user interacts with an item or promotion. This data is then passed along with all subsequent ecommerce events to GA4, ensuring that Item List and Promotion reports are fully populated and ready for analysis.

GA4 Ecom Attributor has two versions:

1. Ecom Attributor for web GTM: Uses first-party cookies to store List and Promotion data.
