Authenticate user on a flow with http request as the trigger

I am trying to create a flow that will allow my users to click on a button and "subscribe" themselves to the specific client - basically get added to a specific list -other flows take over from there.  As I see it I will need to provide two parameters to flow, client name and username. I have already found a way to pass the clientname as a parameter to the http request, my question is , is there a way to know who clicked the button and resolve their username/email?
