JavaScript API

Once the script has loaded, it exposes window.CMP.

Reading consent

window.CMP.consent;

Holds the visitor’s current choice as one true/false value per category — necessary, functional, analytical, marketing.

Reopening the preferences

Give visitors a way to change their mind — a “Cookie settings” link in your footer, for example:

<a href="#" onclick="window.CMP.show(); return false;">Cookie settings</a>

The banner also has an optional floating Cookie Settings button (see Banner design) that does the same without code.

Withdrawing consent

window.CMP.withdraw();

Clears the stored answer, sets every optional category back to refused, and shows the banner again so the visitor can choose afresh.

Events

Event	Fires when
cmp:consent-changed	The visitor makes or changes a choice.
cmp:consent-restored	A returning visitor’s earlier choice is loaded.

Both carry the choice as event.detail.consent:

window.addEventListener('cmp:consent-changed', (event) => {
  if (event.detail.consent.analytical) {
    // start your own analytics
  }
});
