        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

        curl_setopt($ch, CURLOPT_HEADER, 0);

        curl_setopt($ch, CURLOPT_TIMEOUT, self::TIME_OUT);

        $resp = curl_exec($ch);

        if (curl_errno($ch)) {

            return curl_error($ch);

        }

        curl_close($ch);

        return $resp;
