Explainer https://github.com/patcg-individual-drafts/private-aggregation-api#aggregation-coordinator-choice Specification https://github.com/patcg-individual-drafts/private-aggregation-api/pull/106 Summary Modification to the Private Aggregation API to provide a mechanism for selecting which coordinator to use for payload encryption (from a vendor-specified allowlist). The choice of service is made with an additional option in Shared Storage’s run() and selectURL() calls, and in Protected Audience’s runAdAuction() and joinAdInterestGroup() calls. The broad approach largely aligns with Attribution Reporting’s approach (see https://chromestatus.com/feature/5197591256236032). Blink component Blink>PrivateAggregation <https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3EPrivateAggregation> TAG review https://github.com/w3ctag/design-reviews/issues/846 (We have not requested a signal for these changes specifically.) TAG review status Pending Risks Interoperability and Compatibility This feature is optional and backwards compatible. Gecko: No signal (https://github.com/mozilla/standards-positions/issues/805) We have not requested a signal for these changes specifically. The Gecko position on Shared Storage (one of the ways Private Aggregation is exposed) is negative. WebKit: No signal (https://github.com/WebKit/standards-positions/issues/189) We have not requested a signal for these changes specifically. Web developers: No signals Other signals: 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? None Debuggability No new debug capabilities beyond the existing internals page (chrome://private-aggregation-internals) and temporary debug mode. Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)? All but Webview Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ? WPTs will be added when the feature is enabled. Flag name on chrome://flags None Finch feature name PrivateAggregationApiMultipleCloudProviders Requires code in //chrome?
