Key Components

1. Enable 3DS

const config = {
  productId: YOUR_PRODUCT_ID,
  sessionId: 'unique-session-id',
  amount: 2999,
  environment: 'production',
  threeDSRequired: true // Enable 3DS authentication
};

2. Handle 3DS Events

function handleMessage(message) {
  switch (message.type) {
    case 'PAYMENT_3DS_START':
      // 3DS verification started
      showLoadingUI();
      break;
      
    case 'PAYMENT_3DS_SUCCESS':
      // 3DS verification successful
      hideLoadingUI();
      break;
      
    case 'PAYMENT_3DS_ERROR':
      // 3DS verification error
      handleError(message.payload);
      break;
      
    case 'PAYMENT_3DS_FAILURE':
      // 3DS verification failed
      handleFailure(message.payload);
      break;
  }
}

3. Progress Tracking

function updateProgress(stepId) {
  const steps = ['step-1', 'step-2', 'step-3'];
  const currentIndex = steps.indexOf(stepId);

  steps.forEach((step, index) => {
    const element = document.getElementById(step);
    element.classList.remove('active', 'complete');

    if (index === currentIndex) {
      element.classList.add('active');
    } else if (index < currentIndex) {
      element.classList.add('complete');
    }
  });
}

Implementation Steps

Enable 3DS
- Set threeDSRequired: true in configuration
- Ensure proper environment setup
Handle 3DS Flow
- Implement all 3DS event handlers
- Show appropriate loading states
- Handle success and error cases
Add Progress Tracking
- Create progress indicator UI
- Update progress based on events
- Show current step to user
Implement Error Handling
- Handle 3DS-specific errors
- Show user-friendly error messages
- Provide recovery options
Add User Feedback
- Show loading indicators
- Display progress messages
- Confirm successful completion

Best Practices

Clear User Communication

function showUserFeedback(step) {
  const messages = {
    'PAYMENT_3DS_START': 'Verifying your card with 3D Secure...',
    'PAYMENT_3DS_SUCCESS': '3D Secure verification successful',
    'PAYMENT_3DS_ERROR': 'Unable to complete 3D Secure verification'
  };
  
  showMessage(messages[step]);
}

Handle Timeouts

const TIMEOUT_DURATION = 60000; // 60 seconds

let timeoutId = setTimeout(() => {
  handleTimeout();
}, TIMEOUT_DURATION);

function handleTimeout() {
  showError('3D Secure verification timed out. Please try again.');
  updateProgress('step-1');
}

Implement Recovery

function handleError(error) {
  if (error.code === '3DS_UNAVAILABLE') {
    // Fallback to non-3DS payment if allowed
    retryWithout3DS();
  } else {
    // Show error and reset form
    showError(error.message);
    resetForm();
  }
}
