Best Practices

​
Performance Optimization

Load the embed script asynchronously to avoid blocking your page load. The provided embed code already handles this automatically.
<!-- The embed script loads asynchronously by default -->
<script>
// Your embed code here - it won't block page rendering
</script>

​
User Experience

  • Test the chat widget on various mobile devices
  • Ensure the chat bubble doesn’t interfere with mobile navigation
  • Consider using smaller initial messages on mobile screens
  • The widget includes ARIA labels and keyboard navigation
  • Ensure sufficient color contrast in custom styling
  • Test with screen readers for accessibility compliance
  • Pass relevant page/user context to provide better responses
  • Use identity verification for personalized experiences
  • Clear chat context when users navigate to different sections

​
Security Considerations

Never expose sensitive data through the embed script. Use identity verification instead of passing raw user data.

​
Troubleshooting

  1. Check that your agent ID is correct in the embed script
  2. Verify the script is placed correctly in your HTML
  3. Check browser console for JavaScript errors
  4. Ensure your website domain is allowed in agent settings
  1. Ensure event listeners are added after the chatbase script loads
  2. Check that event names are spelled correctly
  3. Verify the chatbase object is properly initialized
  4. Use browser dev tools to debug event flow
