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.

Authorization Information

Each account has all the permissions required to call all APIs, but IAM users must be assigned the required permissions. For details about the required permissions, see Permissions Policies and Supported Actions.
