Can a Domain Name Be Used in a Callback URL?
Yes. You can use either an IP address or a domain name. Both are supported.
If a domain name is bound to multiple IP addresses, perform DNS resolution to confirm that the IP address is reachable. In this case, you are advised to use the IP address in the callback URL.
