Configure web subdomains web-subdomains
When authoring web experiences, if you add content coming from the ۶Ƶ Experience Manager Assets library, you must set up the subdomain that will be used to publish this content.
You can use a subdomain that is already delegated to ۶Ƶ, or you can configure another subdomain. Learn more on delegating subdomains to ۶Ƶ in this section.
-
To access and edit web subdomains, you must have the Manage Web Subdomains permission on the production sandbox.
-
Any modification to a web subdomain will also impact the production sandboxes.
You can create several web subdomains, but only the default subdomain will be used. You can change the default web subdomain, but only one can be used at a time.

Once the checks are successful, the subdomain gets the Success status. It is ready to be used to create web channel configurations.
Note that the subdomain will be marked as Failed if you fail to create the validation record on your hosting solution.
