Squarespace

Squarespace does not allow direct control of the built-in form action, so the most reliable integration is to use a Code Block with your own HTML form. This gives you full control over field names and submission behavior.

Create a Formbase endpoint

Create a new form in the Formbase dashboard and copy the endpoint URL.

Add a Code Block

In Squarespace, add a Code Block to your page and paste an HTML form.

Set the action URL

<form action="https://formbase.dev/s/YOUR_FORM_ID" method="POST">
  <input name="name" placeholder="Name" required />
  <input name="email" type="email" placeholder="Email" required />
  <button type="submit">Send</button>
</form>

Publish the page and submit a test entry.

If you need a custom success experience, handle submission with JavaScript and redirect manually.
