[Webkit-unassigned] [Bug 224884] PCM: Trigger Event

--- Comment #1 from John Wilander <wilander at apple.com> ---
Hi! Thanks for filing. The triggering event needs to be a network request to pcmprep.com that redirects to pcmprep.com/.well-known/private-click-measurement/trigger-attribution/. You should not do a direct request to that location. This enables existing pixels firing for pcmprep.com to work and gives the server pcmprep.com a chance to decide whether this is a real conversion or not before telling the browser to register it.
