Follow these steps to configure subdomains and CNAME records for CDN integration using the standard process.

1. Use the explicit cdnAPI endpoint configuration from the JavaScript run() method.
2. Add a <subdomain>.cdn.<server>.com subdomain. For example, if using Arc XP, you could add a subdomain called latestnews.cdn.arcpublishing.com.
3. Add the subdomain as an extra site domain in the Admin Console. For further information on adding an extra site domain, see the Go-live Guide topic.
4. Configure a CNAME record for the domain, which points to the Zephr API endpoint, {yoursite}.cdn.zephr.com For example, for the site named above, you would configure the CNAME record as follows:

   latestnews.cdn.arcpublishing.com canonical name = latestnews.cdn.zehr.com

   Note: When repeating this process before going live, you must add another production subdomain. For example, latestnews.newspaper.com.
