PCM mentions Modern Triggering of Ad Click Attribution which is a placeholder for a JavaScript API with which ad click destinations can programmatically signal conversions and desired ad click matches as opposed to redirected pixel requests. This functionality is desired because it doesn’t require a network load, it doesn’t require a redirect, it doesn't require third-party requests which leak IP address, referrer et cetera, and it doesn't multiple loads and detections to trigger attribution reports to multiple ad click sources.

How would you like to proceed on specifying this JavaScript API?
