The following Private Aggregation API changes for Protected Audience will be live on M119 Canary by Monday Oct 2nd and will be available in the M119 Beta and Stable releases:

  • Debug mode eligibility

    • The debug mode is only available to callers that are allowed to access third-party cookies. If the caller does not have access to third-party cookies, the debug mode will silently fail. This also means that when third-party cookies are deprecated, the debug mode will no longer be available. 

    • This change is backwards incompatible for callers using enableDebugMode() without third-party cookie eligibility.

  • Report payload padding

    • To avoid the payload size being dependent on the number of contributions, the aggregatable reports will be padded with null contributions to a fixed length.

    • This change will increase the size of the payload sent to the reporting endpoints, and the reporting endpoints using plaintext debug payloads will need to handle the null contributions added. 

    • This change is compatible with existing aggregation service versions.


If you have any questions or comments, reply to this post or open an issue in the Privacy Sandbox Dev Support repository on GitHub.
