Binding a Domain Name

Function

A user-defined domain name takes effect only after the CNAME is added to the subdomain name of the API group. For details, see section "Adding a Record Set of the CAME Type" in the Domain Name Service User Guide.

An API group can be bound to a maximum of five domain names. After you bind a domain name to an API group, APIs in the group can be called using the domain name.
