[HELP] Post data with php CURL

Currently I am trying to post data with cURL and PHP to populate my custom built app. However I can't seem to get anything to work. I can easily post data the same way to the CRM but not to the creator.

This is my code:
  1.     public function serializeModelling($object) {
            // Set the curl address
            $this->curlAddress = 'https://creator.zoho.com/api/xml/write?';
            $this->scope = 'creatorapi';
            $this->token = '***';
            $this->extraParameters = '';
            $xmlData = '<?xml version="1.0" encoding="utf-8"?>
    <ZohoCreator>
            <applicationlist>
                <application name="Modelleren">
                    <formlist>
                        <form name="Modelleren">
                            <add>
                                <field name="Status">
                                    <value>new</value>
                                </field>
                                <field name="Scan">
                                    <value>2</value>
                                </field>
                            </add>
                        </form>
                    </formlist>
                </application>
            </applicationlist>
        </ZohoCreator>';
            // Send data to push method
            $this->pushToZoho($xmlData);
        }


























  2.     public function pushToZoho($xmlData) {
            $ch = curl_init($this->curlAddress); // Bind the address to which we post our data
            echo $this->curlAddress . "<br>";
            curl_setopt($ch, CURLOPT_VERBOSE, 1); //standard i/o streams
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); // Turn off the server and peer verification
            curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
            curl_setopt($ch, CURLOPT_SSL_CIPHER_LIST, 'rsa_rc4_128_sha'); // Set SSL encryption
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //Set to return data to string ($response)
            curl_setopt($ch, CURLOPT_POST, 1); //Regular post
            $query = $this->extraParameters;
            $query .= "&authtoken={$this->token}&newFormat=1&duplicateCheck=2&scope={$this->scope}&xmlData={$xmlData}";
            curl_setopt($ch, CURLOPT_POSTFIELDS, $query); // Set the request as a POST FIELD for curl.
            //Execute cUrl session
            $response = curl_exec($ch);
            // Parse xml response into object
            $this->xmlObject = simplexml_load_string($response);
            echo '<pre>';
            print_r($this->xmlObject);
            echo '</pre>';
            echo curl_error($ch);
            curl_close($ch);
        }





















I'm not getting any responses either.. Any ideas?
