Setup Guide

Takes about 2 minutes

1
Create your form on Boosterpack Forms

Sign in to your account dashboard and create a new form. Add your destination email(s) and optionally connect webhook integrations (Slack, Discord, etc.). Then copy your form ID.

2
Add a Code Block

In the Squarespace editor, add a Code Block to your page (click + → Code). Make sure the Display Source toggle is off. Paste the form HTML into the code block.

3
Add the embed script via Code Injection

Go to Settings → Advanced → Code Injection and paste the embed script in the Header field. This adds spam protection to all pages on your site.

4
Save and activate

Save your page. When you visit the page with your form, you'll see an overlay with an Activate form button. Click it to activate the domain. Your form is live once at least one recipient has confirmed (from Step 1) and the domain is activated.

Code to Copy

Get your form ID from your account dashboard.

Form HTML
Replace <FORM_ID> with your actual form ID
<form method="POST" action="https://boosterpackforms.com/api/forms/<FORM_ID>/submit">
  <input name="name" placeholder="Name" required />
  <input name="email" type="email" placeholder="Email" required />
  <textarea name="message" placeholder="Message" required></textarea>
  <button type="submit">Send</button>
</form>
Embed script
Paste once per page — handles spam protection automatically
<script src="https://boosterpackforms.com/embed.js" defer></script>

Note: Code Injection is available on Squarespace Business and Commerce plans. On Personal plans, you can paste the script directly in the Code Block below the form HTML.

Activating Your Domain

When you create a form, each recipient receives a confirmation email right away — they must confirm before receiving submissions.

When you load a page with your form on a domain that hasn't been activated yet, you'll see an overlay with an Activate form button. Click it to activate the domain. The form goes live once at least one recipient has confirmed and the domain is activated. This only happens once per domain.
