public static String sendRequestManager(String url, String body) throws IOException {
  
    StringBuilder sb = new StringBuilder();
    String result = "";
    BufferedWriter writer = null;
    BufferedReader bd = null;

    URL u = new URL(url);
    HttpURLConnection hc = (HttpURLConnection) u.openConnection();
    // uc.setRequestMethod("GET");
    hc.setRequestMethod("POST");
    hc.setConnectTimeout(5000);
    hc.setReadTimeout(5000);

    hc.setRequestProperty("Content-Type", "application/Json; charset=UTF-8");

    hc.setDoInput(true);
    hc.setDoOutput(true);

    try {

        writer = new BufferedWriter(new OutputStreamWriter(hc.getOutputStream(), "UTF-8"));
        writer.write(body);
        writer.close();

        if (hc.getResponseCode() == 200){
            bd = new BufferedReader(new InputStreamReader(hc.getInputStream(), "utf-8"));
            String s = null
