Reporting API - Users & Events

Hi all,

Just started to use Piwik, we are trying to create a small reports panel on our site which shows a list of events we have recorded in Piwik, I would like to be able to view Events by UserId. I have had a look through the Reporting API Ref and I tried:


This shows the actions but not sure how I can get the link between the users which I have logged with the userId tracking. Any help/advice would be greatly appreciated.
