Add the widget to Squarespace

You need a published widget first.

Squarespace often limits scripts in ordinary blocks. Use Iframe for a form on a page. Use Script in site-wide code injection if you need a modal or floating bar.

A Code block is usually available on paid Squarespace plans.

Inline form on a page or post

1. Edit the page or blog post.
2. Add a Code block.
3. Paste the Iframe snippet from the widget page.
4. Save, then publish.

The form sits in the page. It will not open as a modal over the rest of the site.

Modal or floating bar on every page

Open Settings and find Code injection (under Developer tools on plans that include it). Paste the Script snippet in the footer. Save.

The script loads with every page and opens the modal or bar on click, delay, scroll, or exit intent. Closing it hides it for the rest of that visit.

If nothing shows

Confirm the widget is Published. Confirm your Squarespace plan allows Code blocks or code injection. View the live site, not only the editor overlay. If a block still strips the iframe, try a page that already uses a Code block, or inject the Script snippet site-wide and use an inline layout.

Readers still confirm from their inbox.
