@mholmes You’ll need to define “not working”, how are you debugging? Is your web server receiving the request? Is this code actually executing? All this can be determined with Debug.Log statements, provide your output here. In my apps, I simply write the debug output to a UI Text element during development. You can also use Charles Proxy to monitor the actual networks requests for debugging
private void MyDebug(string debug)
{
Debug.Log(debug);
myText.text += "\r\n" + debug;
}
