Example

Sample Code
C#
string login = "[email protected]";
string password = "p@ssword";
								ServiceSoapClient service = new ServiceSoapClient();
// Prepare AuthenticationData
								LoginInfo loginInfo = service.GetLoginInfo("", login, password);
								AuthenticationData authData = new AuthenticationData();
								authData.AppCode = loginInfo.AppCode;
								authData.UserId = loginInfo.UserId;
								authData.PassCode = password;
								authData.DeptId = loginInfo.DeptId;
								authData.ProjId = loginInfo.ProjId;
string extensionName = "AutomatedTestingBridgeQTP";
bool result = service.Preferences_IsExtensionRestricted(authData, extensionName);
								Console.WriteLine(result.ToString());
							
Java
String login = "[email protected]";
String password = "p@ssword";
								ServiceSoap service = new Service().getServiceSoap12();
// Prepare AuthenticationData
								LoginInfo loginInfo = service.getLoginInfo("", login, password);
								AuthenticationData authData = new AuthenticationData();
								authData.setAppCode(loginInfo.getAppCode());
								authData.setUserId(loginInfo.getUserId());
								authData.setPassCode(password);
								authData.setDeptId(loginInfo.getDeptId());
								authData.setProjId(loginInfo.getProjId());
String extensionName = "AutomatedTestingBridgeQTP";
								Boolean result = service.preferencesIsEntityRestricted(authData, extensionName);
								System.out.println(result);
