    headers['Set-Cookie'] = "system_user=yes; Path=/";
    headers['Set-Cookie'] = "full_name=Administrator; Path=/";
    headers['Set-Cookie'] = "sid=123456789; Expires=Mon, 25-Feb-2019 11:01:39 GMT; Path=/";

    // API RESPONSE
    http.Response response = await http.get(
      apiUrl,
      headers: headers,
    );

    // CONVERT TO JSON AND MAP
    Map responseBody = convert.jsonDecode(response.body);

    return responseBody;
  }

   apiUrl,
   headers: {'Cookie': 'sid=123456789'},
);
