The `data-code` attribute is **required**. Set it to your Account ID (verification code) — AdUnblock uses this value to verify that the script is running on your registered domain. Ad blockers regularly update their rules, and CDN endpoints may become blocked over time. As a site owner, you are responsible for using the latest valid CDN endpoints by regularly checking the System Status page or implementing server-side fetching from `https://public.adunblocker.com/api/vendor_scripts`. Add the following script to your website's `` section: ```html theme={null} ``` **Important:** * Replace `YOUR_VERIFICATION_CODE` with your unique verification code from the dashboard. * Replace `LATEST_SCRIPT_URL` with the current script URL. Fetch the latest script URL from: `https://public.adunblocker.com/api/vendor_scripts` For production environments, implement server-side fetching from our API with proper caching. After adding the script, verify your integration is working properly by navigating to your site and checking if the ads are visible. ## Verification Code Your unique verification code (shown as `YOUR_VERIFICATION_CODE` in the examples above) is required for AdUnblock to verify your integration. This code is specific to your registered domain. ## Available Script Sources We provide multiple CDN endpoints to enhance reliability. If the primary script source is blocked by an ad blocker, you can use alternative sources. **View System Status**: Check our status page to see all available endpoints and their current status. You can also fetch the latest list of valid script sources programmatically from our configuration API: ``` https://public.adunblocker.com/api/vendor_scripts ``` ### Important Notice As a site owner, you are responsible for ensuring your integration uses the latest valid CDN endpoints. Ad blockers regularly update their rules, which may block our endpoints. We recommend: * Regularly check the System Status page for updated endpoint information * For production environments, implement server-side fetching from our API with proper caching * Use the API endpoint `https://public.adunblocker.com/api/vendor_scripts` to programmatically retrieve the latest valid scripts * Never implement client-side fallbacks that fetch from our API directly ## Need help with implementation?
