Failed Authentication Error Handling Tasks

When implementing error handling for failed authentication attempts using the CommerceTools authentication service, it is essential to determine how CommerceTools responds to authentication errors. This includes understanding the specific error codes or messages in the API response that indicate incorrect email addresses or passwords. By processing and understanding these error responses, you can map them to user-friendly error messages that can be displayed in the login form.

Determining CommerceTools Authentication Error Responses

To implement error handling for failed authentication attempts, you need to understand how CommerceTools responds to authentication errors. This involves analyzing the API response from CommerceTools to determine the specific error codes or messages that indicate incorrect email addresses or passwords. For example, CommerceTools may return a specific error code or message in the API response when the email address or password is incorrect.

Implementing a Function or Module to Process Error Responses

Once you have determined how CommerceTools responds to authentication errors, you can implement a function or module in the application to process and understand the error responses from the CommerceTools authentication service. This function or module can be responsible for mapping the error responses from the CommerceTools API to user-friendly error messages that can be displayed in the login form.

Mapping Error Responses to User-Friendly Error Messages

To display user-friendly error messages to inform the user of the issue and guide them on how to proceed, you need to map the error responses from the CommerceTools API to user-friendly error messages. This involves creating a mapping between the error codes or messages returned by CommerceTools and the corresponding user-friendly error messages that can be displayed in the login form.

Visual Implementation Ideas

To display error messages in a consistent and user-friendly manner, you can implement the following visual ideas:

  • Display error messages directly below the respective input field: Display the error message directly below the input field that caused the error. This will help the user understand which field is causing the issue.
  • Highlight the input field in red: Highlight the input field in red to draw the user's attention to the error.
  • Use intuitive icons: Use intuitive icons, such as a warning triangle, next to the error message to enhance the visibility.
  • Ensure error messages disappear once the user corrects the input or starts typing in the respective field: Ensure that the error message disappears once the user corrects the input or starts typing in the respective field.

Acceptance Criteria

To ensure that the error handling implementation meets the requirements, you can use the following acceptance criteria:

  • Clear error messages are shown when authentication fails due to incorrect email or password: Ensure that clear error messages are shown when authentication fails due to incorrect email or password.
  • Error messages are user-friendly and provide guidance on how to proceed: Ensure that the error messages are user-friendly and provide guidance on how to proceed.
  • No sensitive information is exposed to the user in the error messages: Ensure that no sensitive information is exposed to the user in the error messages.
  • The application handles CommerceTools authentication errors properly: Ensure that the application handles CommerceTools authentication errors.

Example Implementation

Here is an example implementation of error handling for failed authentication attempts using CommerceTools:

import requests

def authenticate_user(email, password):
    try:
        response = requests.post('https://commerce-tools.com/api/authenticate', json={'email': email, 'password': password})
        if response.status_code == 200:
            return response.json()
        else:
            raise Exception(response.text)
    except Exception as e:
        return {'error': str(e)}

def map_error_response(error_response):
    if error_response['error'] == 'invalid_email':
        return 'Invalid email address. Please enter a valid email address.'
    elif error_response['error'] == 'invalid_password':
        return 'Invalid password. Please enter a valid password.'
    else:
        return 'An error occurred. Please try again.'

def display_error_message(error_message):
    # Display error message directly below the respective input field
    # Highlight the input field in red
    # Use intuitive icons next to the error message
    # Ensure error message disappears once user corrects input or starts typing in respective field
    pass

In this example implementation, we define a function authenticate_user that attempts to authenticate the user using the CommerceTools authentication service. If the authentication fails, we raise an exception with the error message returned by CommerceTools. We then define a function map_error_response that maps the error response from CommerceTools to a user-friendly error message. Finally, we define a function display_error_message that displays the error message in a user-friendly manner.

Conclusion

Q: What are the common error codes or messages returned by CommerceTools when authentication fails?

A: CommerceTools may return the following error codes or messages when authentication fails:

  • invalid_email: The email address is invalid or does not exist.
  • invalid_password: The password is incorrect or does not match the email address.
  • account_locked: The account is locked due to too many failed login attempts.
  • account_disabled: The account is disabled due to a security reason.

Q: How can I determine the specific error codes or messages returned by CommerceTools?

A: You can determine the specific error codes or messages returned by CommerceTools by analyzing the API response from CommerceTools. You can use tools such as Postman or cURL to send a request to the CommerceTools API and inspect the response.

Q: What is the best way to display error messages to the user?

A: The best way to display error messages to the user is to display them directly below the respective input field that caused the error. You can also highlight the input field in red to draw the user's attention to the error. Additionally, you can use intuitive icons next to the error message to enhance the visibility.

Q: How can I ensure that error messages disappear once the user corrects the input or starts typing in the respective field?

A: You can ensure that error messages disappear once the user corrects the input or starts typing in the respective field by using JavaScript to remove the error message when the input field is updated.

Q: What are the acceptance criteria for implementing error handling for failed authentication attempts using CommerceTools?

A: The acceptance criteria for implementing error handling for failed authentication attempts using CommerceTools are:

  • Clear error messages are shown when authentication fails due to incorrect email or password.
  • Error messages are user-friendly and provide guidance on how to proceed.
  • No sensitive information is exposed to the user in the error messages.
  • The application handles CommerceTools authentication errors properly.
