Squarespace form to email

In Squarespace, add the form as HTML with a Code Block.

Plan: which Squarespace plans allow Code Blocks and custom code has changed over time. Check Squarespace’s current plan details before you start.

Edit the page, add a block and choose Code.
Make sure the block is set to HTML, then paste the form and replace YOUR_ACCESS_KEY with your key from app.formdoc.dev/new:

HTML

<form action="https://api.formdoc.dev/v1/submit" method="POST">
  <input type="hidden" name="access_key" value="YOUR_ACCESS_KEY">
  <label for="fd-name">Name</label>
  <input type="text" id="fd-name" name="name" required>
  <label for="fd-email">Email</label>
  <input type="email" id="fd-email" name="email" required>
  <label for="fd-message">Message</label>
  <textarea id="fd-message" name="message" required></textarea>
  <input type="checkbox" name="botcheck" style="display:none" tabindex="-1" autocomplete="off">
  <button type="submit">Send</button>
</form>
