What does "at the same place" mean? Fields aren't positional so there's no way of saying "grab the value from the second field". If the name is dynamic, how would you know which field you're looking for?
I see what you mean, I think I'll need some string manipulation for that...
Btw, do you access the fields like this in an "IF" statement?
=> if [jsonData][response][isSuccessful] == true
or
=> if %{[jsonData][response][isSuccessful]} == true
