<h3>External services</h3>
This plugin connects to one external service: fantasticforms.com, operated by Fantastic Forms.
<ol>
<li>
Embedding forms (front-end iframe) — When a visitor loads a page that contains the Fantastic Forms block or <code>[fantastic_form id="…"]</code> shortcode, their browser loads <code>https://fantasticforms.com/f/<form_id></code> inside an iframe. The plugin itself does not transmit any data; the iframe behaves like any other embedded form. Submissions go directly from the visitor’s browser to fantasticforms.com and are governed by the form’s own settings.
</li>
<li>
Listing your forms in the block editor (optional, Pro only) — When you paste a Pro API key under Settings → Fantastic Forms and the API key is non-empty, the plugin calls <code>GET https://fantasticforms.com/api/v1/forms</code> so the block editor’s dropdown can list your forms. The request is authenticated with the API key you provided and sends no data about your site, your visitors, or your WordPress installation. The response is cached for 5 minutes in a WordPress transient. If you do not save an API key, no external request is ever made by the plugin itself.
</li>
</ol>
Use of the fantasticforms.com service is governed by Fantastic Forms’ Terms of Service and Privacy Policy:
<ul>
<li>Terms of Service: https://fantasticforms.com/legal/terms</li>
<li>Privacy Policy: https://fantasticforms.com/legal/privacy</li>
</ul>

Embed Fantastic Forms — typeforms, surveys, calculators, payment forms, schedulers — anywhere on your WordPress site with a block or shortcode.
