Code-based customizations

You can use custom code-based modifications when a feature, functionality, or embedded content isn’t available in Squarespace. Unlike our official integrations, all code-based customizations fall outside of the scope of Squarespace support.

Adding a custom modification usually involves pasting code provided by a third-party service into a code block or code injection. Specific steps vary by service.

Since these are code-based solutions, we can’t guarantee their functionality or full compatibility with Squarespace. This includes their ability to function with our responsive design, particularly their appearance on mobile devices.

Code-based customizations usually involve code injection and adding advanced code to the code block. These are premium features available in Business and Commerce plans.

Using a different third-party service

If a service isn’t on the list, this doesn’t mean you can’t add it to Squarespace. If the service has embeddable widgets, HTML, and/or JavaScript code for adding content or functionality to a website, you may be able to add it to your site using a code block, embed block, or code injection.

Where to go for support

We don't provide support for code-based modifications, unless otherwise specified. This means that we’re unable to help further with setup or troubleshooting.

If a customization is unsupported, there are links at the bottom of its guide to point you in the right direction, like a third-party's documentation or support team, our peer-to-peer Squarespace Forum, or Squarespace Experts.
