Thank you really appreciate the help 🙂 Should I put an underscore in front of the variable name in the Vapi System Prompt or the variable name the server response sends the data as. Does the response variables have to match pre-existing tool properties variables or can then be completely new variable names. Also curious on the best way to call the variables from the server response in the System Prompt, I didn't see this covered in Docs. Do I use {{sys response variable}}, or [sys response variable] or "sys response variable" to call system response variables values? Really appreciate the help, once I get this fixed everything should work
