Fantastic!

<h3>External services</h3>
This plugin connects to the VerticalResponse API to authenticate your account, load your available lists, create new lists from wp-admin, and add popup subscribers to the selected VerticalResponse list.
It sends data to VerticalResponse in these situations:
<ul>
<li>When an administrator saves plugin credentials or the plugin refreshes its access token, it sends the configured <code>client_id</code> and <code>client_secret</code> to the VerticalResponse authorization endpoint.</li>
<li>When an administrator opens the Builder or Settings screens, it sends the access token to VerticalResponse to load the available lists.</li>
<li>When an administrator creates a new list from Settings, it sends the new list name to VerticalResponse.</li>
<li>When a site visitor submits the popup form, it sends the selected list ID plus the popup form fields you have enabled, such as email, first name, last name, company, city, and state/region.</li>
</ul>
