It tracks ad clicks/views (attribution source events) and subsequent conversions (attribution trigger data), matching them within the browser. Two report types exist: event-level, which offer limited conversion data with noise and delay for privacy, and summary reports, which aggregate data. The API, available in Chrome, employs techniques like partitioned identity, noising, and encryption to prevent cross-site user tracking while enabling conversion measurement. The API can work in third-party iframes, and between apps and the web.\n"]]
