Respond to these requests with the `Attribution-Reporting-Register-Trigger` header, specifying trigger data like `trigger_data`, `priority`, and `deduplication_key` within a JSON array, or `aggregatable_trigger_data`. The `attributionsrc` attribute is optional for HTML elements but is useful to make a separate request. For JavaScript calls the `attributionReporting` option is required. Ensure the origin of the request matches the source registration origin.\n"]]
