var S: TStringList;
   M: TStream;
begin
 S := TStringList.Create;
 M := TMemoryStream.Create;
 try
   S.Values['Email'] := 'your google account';
   S.Values['Passwd'] := 'your password';
   S.Values['source'] := 'estream-sqloffice-1.1.1.1';
   S.Values['service'] := 'cl';

   IdHTTP1.IOHandler := IdSSLIOHandlerSocketOpenSSL1;
   IdHTTP1.Request.ContentType := 'application/x-www-form-urlencoded';
   IdHTTP1.Post('https://www.google.com/accounts/ClientLogin', S, M);
   Memo1.Lines.Add(Format('Response Code: %d', [IdHTTP1.ResponseCode]));
   Memo1.Lines.Add(Format('Response Text: %s', [IdHTTP1.ResponseText]));

   M.Position := 0;
   S.LoadFromStream(M);
   Memo1.Lines.AddStrings(S);
 finally
   S.Free;
   M.Free;
 end;

end;
