Consent is stored in a cookie in the format groups=cat1:cat2&datestamp=X&version=X. The cookie is SameSite=Lax with the Secure flag.

Yes. Besides the default categories (essential, analytical, preferences, marketing), you can add any number of custom categories.

Optionally, you can configure a server endpoint where consent records are sent for audit purposes. This is an advanced feature for companies that need centralized consent tracking.

Create a new Custom HTML tag, paste the generated code, and set the trigger to Consent Initialization - All Pages. After publishing the container, the banner will appear on all pages.

Yes. Copy the generated code and paste it before the closing </body> tag of your page. GTM is not required.

Simply generate new code in the builder and replace the old tag in GTM. If a user already gave consent and the cookie version hasn't changed, the banner won't show again.

In the builder you can see a live preview. After deploying to GTM, use Preview mode to test on your site before publishing.
