I will check it in the morning to see if I can change/update the "total" 
field, definitely.

Some kind of built-in error response possibility would be nice too. 
Right now I'm hard coding things like
Response.Content := '{ "success" : false, "message" : "' + MyErrMsg + '"}';
when there was an exception in my code or incorrect user entry was 
passed from the client, etc.
