If you have one or more subdomains activate for your web site and want to share the Cookie Consent between all of them to avoid the dialog showing up again for each subdomain you can set the domain of the cookie using the following code:

<script src="https://cookie.consent.is/cc/xxxxxxx.js"></script>
<script type="text/javascript">
window.addEventListener("load", function() {
  cookie:  {
    domain: 'consent.is'

Set the domain parameter to your top level domain.
