Third-party customizations in Squarespace 5

You can use custom third-party modifications when a feature, functionality, or embedded content isn’t available in Squarespace 5. All third-party customizations fall outside of the scope of Squarespace support.

Since these are code-based solutions, we can’t guarantee their functionality or full compatibility with Squarespace 5. This includes their appearance on mobile devices.

General steps

Adding a custom modification usually involves code provided by a third-party service. Specific steps vary by service. As a general rule:

  • On the page - For widgets that appear on a specific page, post, or sidebar, add the code as a code snippet.
  • Entire site - For modifications that affect your whole site, add the code to Code Injection.
  • </body> or footer - If modifications ask you to add code before the </body> tag or "in the footer code," add it to your site footer.

When in doubt, reach out to the company providing the code.

Example 1 - TokBox

TokBox is a way to add video chat options to your site.

  1. Follow the steps in TokBox's documentation to copy the embed code.
  2. Paste your code into a code snippet.
  3. If prompted, enable access to your camera and microphone by clicking allow.
  4. Once a video chat has been initiated, you can moderate your session by checking I'm a moderator and typing in the secret code you received from Tokbox.
