What I am trying to do is: a user opens link to domain1.com → there is a forwarding on domain1.com to domain2.com. I would like to track everyone who is going from domain1.com to domain2.com. With UA it would be possible to integrate a pixel like mentioned above and then forward. How to do it with piwik pro?
Hi! I assume that the src for this pixel was bit different and used the UA tracking API. It works similarly in Piwik PRO. Our tracking endpoint supports a param (send_image) that generates a pixel in response. All docs are available here: Tracking HTTP API — Piwik PRO Analytics Suite 16.39 documentation
