[FEAT]: API Endpoint for Forgot and Reset Password

[AdeGneus]

Description

Implement an API endpoint for forgot and reset password functionality. This endpoint allows users to request a password reset link and reset their password using a token provided in the request parameters.

Endpoint Feature

• This endpoint enables users to request a password reset link via email and reset their password using the provided token.
• Limited to sending reset links to registered users' email addresses.

Acceptance Criteria

• The forgot-password endpoint should be accessible at POST /api/v1/auth/forgot-password.
• The reset-password endpoint should be accessible at POST /api/v1/auth/reset-password/:token.
• The forgot-password endpoint should accept HTTP POST requests to send a reset link via email.
• The reset-password endpoint should accept HTTP POST requests to reset the password using a token.
• The forgot-password endpoint should return a 200 OK status code with a success message in the response body.
• The reset-password endpoint should return a 200 OK status code with a success message in the response body.

Request Example (Forgot Password):
POST /api/v1/auth/forgot-password
Content-Type: application/json

{
  "email": "[email protected]"
}

Response Example (Forgot Password):

{
  "status": "success",
  "status_code": 200,
  "message": "Password reset link sent successfully."
}

Request Example (Reset Password):
POST /api/v1/auth/reset-password/:token
Content-Type: application/json

{
  "new_password": "newPassword123",
}

Response Example (Reset Password):

{
  "status": "success",
  "status_code": 200,
  "message": "Password reset successfully."
}

Data Validation

Input Validation:

• Confirm that email is provided and valid.
• Confirm that new_password is valid.
• Confirm that token is valid
• Example: If email is invalid or missing, return a 400 status code with an error message.

{
  "status": "unsuccessful",
  "status_code": 400,
  "message": "Valid email must be provided."
}

• Example: If new_password is invalid or missing, return a 400 status code with an error message.

{
  "status": "unsuccessful",
  "status_code": 400,
  "message": "Valid new password and password confirmation must be provided."
}

Output Validation:

• Ensure the response format is correct and includes appropriate status codes and messages.
• If there is an error during the process, the API should return a 500 Internal Server Error status code with an appropriate message.

{
  "status": "unsuccessful",
  "status_code": 500,
  "message": "Failed to process request. Please try again later."
}

Authentication and Authorization

Authentication:

• Authentication is not required for accessing the reset-password endpoint as the token serves as the authentication method.

Error Handling

Error Responses:

• Define error responses for common failure scenarios.
• Example: If the reset token is invalid or expired, return a 400 status code with an error message.

{
  "status": "unsuccessful",
  "status_code": 400,
  "message": "Invalid or expired reset token."
}

Edge Cases:

• Consider edge cases such as multiple reset requests and expired tokens.

Performance and Security

Performance Considerations:

• Review potential performance implications and optimize the API for efficiency.
• Example: Implement rate limiting to prevent abuse.

Security Concerns:

• Address security considerations such as data sanitization.
• Example: Sanitize user inputs to prevent injection attacks.
• Ensure the reset tokens are securely generated and stored.

Documentation

API Documentation:

• Ensure that API documentation is updated to include details about the new endpoints, request/response formats, error handling, and authentication requirements.

Technical Notes:

• Include any additional technical notes or considerations.

Testing Requirements

Unit Tests:

• Write unit tests to validate input data and forgot/reset password logic.

Integration Tests:

• Ensure end-to-end functionality is tested with integration tests.

Dependencies and Impact

Dependencies:

• Identify dependencies on other tasks or systems, such as user authentication.

Impact Analysis:

• Assess the potential impact on other features or components, ensuring that existing functionality is not disrupted.
