For event-level reports, clicks allow 64-bit `source_event_id`, 3-bit `trigger_data`, and up to 3 attributed conversions; views use 64-bit `source_event_id`, 1-bit `trigger_data`, and 1 conversion. Noise is applied to reports with a randomized response, and there is a 1-hour to 30-day reporting delay. Aggregatable reports have a 65536 total bucket value limit, a maximum of 20 reports per source, and 20 contributions per report. There are also limits on the number of unique destinations, attributions, reporting origins, and trigger registration header size.\n"]]
