Currently the API performs filtering after a source is chosen based on matching <reporting origin, destination site> fields. This results in API callers either not receiving attribution reports or incorrect attribution in scenarios where there are multiple different advertisers/campaigns that all convert on the same destination site. This change allows API callers to now specify a field called "attribution_scopes" which will be used for filtering before starting the regular attribution flow. This allows API callers more fine grained control over the attribution granularity and the ability to receive proper attribution reports in the scenario described above (i.e. where there are multiple different advertisers/campaigns that all convert on the same destination site). This change directly addresses API caller feedback and allows them to have more control over their attribution filtering. Explainer/Spec changes 1. Explainer: https://github.com/WICG/attribution-reporting-api/blob/main/attribution_scopes.md 2. Spec: https://github.com/WICG/attribution-reporting-api/pull/1215 Risks Interoperability and Compatibility This is an optional and fully backwards compatible change. This feature provides a new field for specifying filters that can be checked before the regular attribution process takes place and does not break any pre-existing API or web functionality. Gecko: No signal (Original request: https://github.com/mozilla/standards-positions/issues/791) WebKit: No signal (Original request: https://github.com/WebKit/standards-positions/issues/180) Web developers: https://github.com/WICG/attribution-reporting-api/issues/1229 WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? No 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> ? No, currently the behavior around attribution scopes is not covered in WPT due to difficulty of adding significant coverage for the feature because of API-mandated delays and noise. However, the feature is covered by comprehensive integration tests (commonly referred to as “interop tests”) that are also reusable by other implementations. Estimated milestones This feature is anticipated to ship as part of Chrome 130 <https://chromiumdash.appspot.com/schedule>.
