You can use custom third-party modifications when a feature, functionality, or embedded content isn’t available in Squarespace. Unlike our official integrations, all third-party 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 functioning with our responsive design, particularly their appearance on mobile devices.
Tip: For official integrations we support, visit Squarespace integrations.
Third-party customizations usually involve Code Injection and adding advanced code to the Code Block. These are Premium features available in Business and Commerce plans.

Where to go for support
We don't provide support for third-party 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 Answers forum, or Squarespace Experts.
Using your third-party service
For help, we recommend starting with your service’s documentation or contacting their support teams. Find a relevant help article on their site, or ask them for embed code you can add to Squarespace. You can also search our Answers forum for peer-to-peer advice. If you need professional coding or design assistance, a Squarespace Expert can help.
Adding an external link
Adding a direct link to a site outside of Squarespace doesn’t require a custom modification. There are many options for linking to other sites, such as a navigation link, button, or image clickthrough URL. In some situations, this can be a more elegant solution than embedding a third-party service on your site.
