            CURLOPT_RETURNTRANSFER => true,

        $this->response = json_decode(curl_exec($curl));

It seems like curl_exec($curl) can also be of type true; however, parameter $json of json_decode() does only seem to accept string, maybe add an additional type check?

        curl_close($curl);
    }
