Where I have to find userid after using uid parameter


I have added user id for login in my query using uid parameter now where I can see my user id.
I want to fetch my all events and actions on the basis of user_id instead of visitor_id.


This is available in latest version of Piwik. The parameter will then be available Visit (i.e. when defingin a segment). For further details on user id (uid paratmer usage) see User ID - Analytics Platform - Matomo
