public ResponseEntity<String> doJsonRequest(HttpMethod httpMethod, String path, Object body) throws URISyntaxException {
    RestTemplate restTemplate = new RestTemplate(new HttpComponentsClientHttpRequestFactory());

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);
    headers.add(COOKIE, getWebdriver().manage().getCookieNamed(YOUR_APP_COOKIE_NAME).toString());
