Ability to report DSP IG Bidding Activity

[sunnypav]

I am looking for a way to fire an event which could give us the ability to report back to our own servers which contains the information about campaign Ids and if possible the IG names on bid. I could see there is a way using sendReportTo function but we see its for each IG which can make it lot of events. Can you think about adding a function central to all the bids & non bids which could give DSP the ability to send this information to the backend servers which can be used for improving reporting/model training & optimisation.

Can anyone help me with this query on how one can implement the reporting of ondevice bidding activity ? I don't seem to see any suitable solution for the same.

To report something about all of your different bids in an auction, you could write information to Shared Storage, later perform whatever sort of on-device analysis and summarization you want, and then use Private Aggregation to send a summary report. This report will be in the form of a contribution to a noised histogram — that is, you should not expect to use it to learn about individual events. That is deliberate: learning about all the bids in a specific auction, at the event level, would constitute cross-site tracking.
