ERA serverAPI getting uuid

[kornwaretm 0]

hi i'm running era 6.5 on ubuntu. i'm trying to find a way to access uuid from static group id, dynamic group id. I need to get these information for making some automatic operations. But i cant seems to find a way to access those information via JSON. the only way i can figure out how to get those information is via database access. Am i missing something? or accessing the data base is the correct way? 

thanks
