Can I Bind Private Domain Names for API Access?

In the shared gateway on the old console, the domain name to be bound must have been registered, and there must be CNAME records pointing the domain name to the subdomain name of the group to which the target API belongs. You cannot bind private domain names or domain names that do not support public access to API groups.

In a dedicated gateway, you can add a private domain name (filing not required), and add an A record to point the domain name to the inbound access address of the gateway.
