Webflow

CookieBoss works with Webflow out of the box. Add a single script tag to your project settings and your consent banner will appear on every page.

Step 1: Add the CookieBoss script

1. In Webflow, go to Project Settings → Custom Code
2. Paste the following into the Head Code section:

<script async src="https://cdn.cookieboss.io/scripts/YOUR_SITE_ID/consent.js"></script>

3. Replace YOUR_SITE_ID with the Site ID from your CookieBoss dashboard (Settings → Installation)
4. Click Save Changes, then Publish your site

Step 2: Verify the installation

1. Open your published Webflow site in an incognito/private window
2. The CookieBoss consent banner should appear
3. Open the browser console and run:

console.log(window.CookieBoss)

If the script loaded correctly, this will log the CookieBoss API object.

Optional: Google Consent Mode

If you use Google Analytics or Google Ads, add the Google Consent Mode snippet before the CookieBoss script in the Head Code section:

<!-- Google Consent Mode v2 defaults -->
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('consent', 'default', {
  analytics_storage: 'denied',
  ad_storage: 'denied',
  ad_user_data: 'denied',
  ad_personalization: 'denied',
  wait_for_update: 500
});
</script>

<!-- CookieBoss (updates consent state automatically) -->
<script async src="https://cdn.cookieboss.io/scripts/YOUR_SITE_ID/consent.js"></script>

CookieBoss will automatically update the consent state when the visitor makes a choice. No additional configuration is needed.

Optional: Block third-party scripts until consent

For scripts you add via Webflow’s custom code or embed elements, change the type attribute to text/plain and add a data-cookieboss-category attribute. CookieBoss will activate them only after the visitor consents to that category.

<!-- This script won't run until the visitor consents to "marketing" -->
<script type="text/plain" data-cookieboss-category="marketing"
src="https://example.com/pixel.js"></script>

Supported categories: necessary, functional, analytics, marketing.
