Can i send information to testrail for selenium when my test runs its course

IM trying to send my tests to testrail from selenium but im not using an assert to end the test, i just want it to pass if it runs to completion? Is this possible? Also is there any examples of how this working in the code? I currently have:

public class login_errors extends ConditionsWebDriverFactory {

public static String TEST_RUN_ID                = "R1713";
public static String TESTRAIL_USERNAME          = "f2009@hotmail.com";
public static String TESTRAIL_PASSWORD          = "Password100";
public static String RAILS_ENGINE_URL           = "https://testdec.testrail.com/";
public static final int TEST_CASE_PASSED_STATUS = 1;
public static final int TEST_CASE_FAILED_STATUS = 5;


@Test
public void login_errors() throws IOException, APIException {
    Header header = new Header();
    header.guest_select_login();
    Pages.Login login = new Pages.Login();
    login.login_with_empty_fields();
    login.login_with_invalid_email();
    login.email_or_password_incorrect();
    login.login_open_and_close();
    login_errors.addResultForTestCase("T65013",TEST_CASE_PASSED_STATUS," ");

}
public static void addResultForTestCase(String testCaseId, int status,
                                        String error) throws IOException, APIException {

    String testRunId = TEST_RUN_ID;

    APIClient client = new APIClient(RAILS_ENGINE_URL);
    client.setUser(TESTRAIL_USERNAME);
    client.setPassword(TESTRAIL_PASSWORD);
    Map data = new HashMap();
    data.put("status_id", status);
    data.put("comment", "Test Executed - Status updated automatically from Selenium test automation.");
    client.sendPost("add_result_for_case/"+testRunId+"/"+testCaseId+"",data );

}

}

And Im getting a 401 status
