I have connected Unity to Moodle using PHP. I can successfully generate user token in Unity, but when ad will send a post request to Moodle using my custom plugin in Moodle I get this error. 

      response: <?xml version="1.0" encoding="UTF-8" ?>

      <EXCEPTION class="invalid_parameter_exception">

     <ERRORCODE>invalidparameter</ERRORCODE>

     <MESSAGE>Invalid parameter value detected (Missing function name)</MESSAGE>

     <DEBUGINFO>Missing function name</DEBUGINFO>

     </EXCEPTION>

I know the error is because of Missing function name but I added it correctly in my query like :

       $parametersArray = array('wstoken' => $token , 'wsfunction' => $function , 'moodlewsrestformat' => 'json'');

this is the code for curl that I use

        $curl = curl_init($url);

        curl_setopt($curl, CURLOPT_POST, true);

        curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($data));

        curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded')); 

        curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

        $response = curl_exec($curl);

        curl_close($curl);

        return $response;

I add wsfunction like core_course_get_module. of course I add id=99 to  $parametersArray after that line.
