Currently aggregatable reports generated by the API can consist of multiple separate contributions which are key:value pairs. API callers can batch together aggregatable reports and then process them in the aggregation service, which consists of decrypting the reports, aggregating the values, and adding noise, before returning a summary report to the API caller. Additionally, all contributions in an aggregatable report must currently be processed by aggregation service at the same time. With this change, the API will now allow API callers to specify filtering IDs as part of each contribution (i.e. each key:value pair) in the aggregatable report. API callers can then use these filtering IDs, which will also be part of the encrypted payload of the report, to specify which contributions they want to have processed by the aggregation service at a given time. This will allow API callers to process contributions with different filtering IDs at different cadences. Allowing this flexibility is a utility improvement, because the noise added in the aggregation service per key:value pair bucket may have a lower relative impact on values that are batched on a longer cadence. Explainer/Spec changes 1. Flexible contributions filtering <https://github.com/WICG/attribution-reporting-api/pull/1290> Risks Interoperability and Compatibility This is an optional and fully backwards compatible change. This feature provides a new filtering ID that can be set as part of the aggregatable report contributions and does not break any pre-existing API or web functionality.

None 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 128 <https://chromiumdash.appspot.com/schedule>.
