Custom code empowers you to extend Squarespace's functionality beyond built-in features. While these modifications aren't officially supported, they open up possibilities for advanced customization.

Common ways to add custom code:

  • Code blocks
  • Code injection
  • Embed blocks

Popular code-based customizations include:

  • AdSense for displaying ads
  • Apple Touch Icon for iOS bookmarking
  • BeerMenus for drink menus
  • Bloglovin' for blog verification
  • Etsy shop integration
  • Eventbrite for event registration
  • Facebook Pixel for tracking
  • Feedly RSS integration
  • Issuu for PDF embedding
  • MLS search for real estate
  • Swiftype for advanced search
  • Zocdoc for appointment booking

Adding Third-Party Services:

  1. Check if the service provides embeddable widgets, HTML, or JavaScript
  2. Use appropriate code insertion method (code block, embed block, or code injection)
  3. Test functionality across devices
  4. Consider mobile responsiveness

Important Considerations:

  • Custom code may not be fully responsive
  • Functionality isn't guaranteed
  • Support is limited for code-based modifications
  • Third-party service documentation is your primary resource
  • Consider official Squarespace Integrations or Extensions first

For Support:

  • Consult third-party service documentation
  • Visit the Squarespace Forum
  • Connect with Squarespace experts
  • Enterprise customers can access additional support at squarespace.com/enterprise

Remember that while custom code offers flexibility, it's important to evaluate whether an official integration or third-party service might better suit your needs.
