Explainer Attribution Reporting with event-level reports <https://github.com/WICG/attribution-reporting-api/blob/main/EVENT.md> Attribution Reporting API with Aggregatable Reports <https://github.com/WICG/attribution-reporting-api/blob/main/AGGREGATE.md> Aggregation Service for the Attribution Reporting API <https://github.com/WICG/attribution-reporting-api/blob/main/AGGREGATION_SERVICE_TEE.md> Specification https://wicg.github.io/attribution-reporting-api/ Blink component Internals > AttributionReporting <https://bugs.chromium.org/p/chromium/issues/list?q=component:Internals%3EAttributionReporting> Summary We are landing the following change to the Attribution Reporting API focused on: - applying element-level referrer policy for specific html elements This change is based on ad-tech feedback <https://github.com/WICG/attribution-reporting-api/issues/382> and so that attributionsrc requests are treated like other subresources on the page. Currently when the API is called through the use of the attributionsrc attribution as part of various html elements (i.e. <img>, <script>, <a>, or window.open), it ignores the resource-level referrer policy attribute set on the html element. With this change the attributionsrc request will now apply the same resource-level referrer policy set in the <img>, <script>, <a>, or window.open. This will allow ad-techs more control over whether or not they want to be more or less restrictive regarding the referrer information on their attributionsrc requests. Explainer/Spec changes 1. Use referrer policy for background attributionsrc requests <https://github.com/WICG/attribution-reporting-api/pull/1254> Risks Interoperability and Compatibility This feature is not a strictly backwards compatible change because before the change the resource-level policy was ignored, but now it is not ignored. Given this change, the value of the request's referrer header may be different than before. This breakage is unlikely, because it would require an API caller to have a different referrer policy on the document and on the resource, which is unlikely for the Attribution Reporting API. Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)? The attribution reporting feature will be supported on all platforms with the exception of Android WebView Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ? Yes Estimated milestones This feature is anticipated to ship as part of Chrome 126 <https://chromiumdash.appspot.com/schedule>.
