Is it possible to change only the value of a variable via a JSON command?

Instead of:
/json.htm?type=command&param=updateuservariable&idx=1&vname=VariableName&vtype=2&vvalue=NewValue

Use:
/json.htm?type=command&param=updateuservariable&idx=1&vvalue=NewValue

or:

/json.htm?type=command&param=updateuservariable&idx=1&vtype=2&vvalue=NewValue

for example?

It's very easy to change the variable name by accident when creating JSON commands on other devices

Not sure how this is solved?
Nobody ever answered me...

Nor Me I've trying to change the thermostat setpoint on a device through JSON. I'm going to experiment, there is a page on this stuff but I sort of expected a bit more detail. its in my JSON Post

the page is at http://www.domoticz.com/wiki/Domoticz_API/JSON_URL%27s

Below how I change a uservariable of type string

http://ip:port/json.htm?type=command&param=updateuservariable&idx=12&vname=test&vtype=0&vvalue=0

I can't set my setpoint.
This is what I have, I try to send;
http://192.168.178.25:8080/json.htm?typ ... e=SetPoint;
I send 33 degrees, Data and Setpoint changed to zero (0.0) degrees.

Do I something wrong?

To get the values works perfect with this script;
$json_string = file_get_contents("http://192.168.178.25:8080/json.htm?typ ... es&rid=$id");
$parsed_json = json_decode($json_string, true);
$parsed_json = $parsed_json['result'][0];
$q = $parsed_json[$item];

to the question from cjnicholl

According to the source code, you have to provide all the variables:
if (idx.empty() || variablename.empty() || variablevalue.empty() || variabletype.empty())
return;
