Sendpospill according to the site documentation accordingly. JSON-request is formed as follows:

url url = new url ("http://youurrl.com");
HttpsurlConnection Conn = (httpsurlconnection) url.openconnection ();
Conn.SetreadTimeout (10,000);
Conn.setConnectTimeout (15000);
Conn.setRequestmethod ("POST");
Conn.Setdooutput (True);
// Request design, for example {"auth": {"UserName": ADM, "Password": pwd}, "coord": {"x": 23, "y": 255}}
Jsonobject myjson = new jsonobject ();
Jsonobject auth = new jsonobject ();
Auth.put ("UserName", "Adm");
auth.put ("Password", "pwd");
coords.put ("x", "23");
coords.put ("Y", "255");
MyJSon.put ("Auth", auth.tostring ());
myjson.put ("coords", coords.tostring ());
Con.setRequestProperty ("Content-Type", "Application / JSON; Charset = UTF-8");
// Display Query Result
OutputStreamwriter WR = New OutputStreamWriter (Con.getOutputstream ());
WR.WRITE (Myjson.tostring ());
wr.flush ();
STRINGBUILDER SB = new stringbuilder ();
int httpresult = con .GetResponsecode ();
if (httpresult == httpurlconnection.http_ok) {
  BufferedReader Br = New InputStreamReader (Con.getInputStream (), "UTF-8"));
  String Line = NULL;
  While ((Line = Br.ReadLine ())! = NULL) {
    SB.APPEND (LINE + "\ N");
  Br.Close ();
  System.out.PrintLN ("" + sb.tostring ());
} else {
  System.Out.PrintLN (Con.GetResponsemessage ());
