First week with DF 
I've already read the doc, but its not exactly what i want.
I dont want to use params to select what operation/action i will run, if i can use the url (i just dont know how exactly) 
, but its possible, DF use this in his native services (system).
Did you keep these scripts in files or each script is a custom service and you use platform.api.get to invoke?
You could post some examples of your "Request URL"?
Thanks!
