API callback

$this->api->transmit($arr);

$arr has to contain the following parameters: 'url' => 'www.codengine.net', // the url to transmit to 'whattosend' => $_GET['id'], // all the parameters to send to the url

You may set another parameter: 'mode' which will set the API callback type: get or post. Default value: get

Happy coding ;)
