You can view a user’s profile by going to Activity → User Activity and entering their mParticle ID (MPID) or a known unique identity (i.e. Customer ID, Email Address).
If you don’t know a user’s MPID, you can find it by reviewing incoming data in Data Master → Live Stream, or you can print the MPID in your app debugger. For example, you can invoke mParticle.Identity.getCurrentUser().getMPID() in a web browser console to obtain the MPID from our web SDK.
