var
success: Integer;
http: TChilkatHttp;
url: WideString;

success := 0;

http := TChilkatHttp.Create(Self);

url := 'https://example.com/something';
jsonText := '{ ... }';

//  ------------------------------------------------------------------------
//  The PostJson method is deprecated:

responseObj := http.PostJson(url,jsonText);
if (http.LastMethodSuccess = 0) then
  begin
    Memo1.Lines.Add(http.LastErrorText);
    Exit;
  end;

//  Your application creates a new, empty HttpResponse object which is passed 
//  in the last argument and filled upon success.

responseOut := TChilkatHttpResponse.Create(Self);
success := http.HttpStr('POST',url,jsonText,'utf-8','application/json',responseOut.ControlInterface);
