Discussion

The device generates the AdImpressionRequest and sends it in the body of a Get a Signed Web Ad Impression Payload request. The device uses the value from the attributionSourceNonce in a web ad link for the source_nonce value in this request. The ad network looks up the fully signed web ad impression using the source_nonce value, which it creates when it serves the attributable ad link.
