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 involve using custom code. Code Injection and adding advanced code to the Code Block are Premium features available in the current Website Business plan and higher:
- Available in: All Business and Commerce plans
- Available in: Legacy Personal plan (no longer available for new subscriptions)
- Not available in: Current Personal plan
- Trial: You can use Code Injection and the Code Block during a trial.

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 Specialists.
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 Specialist 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.
