Why is REST API also using port 8443 other than 443?

This is the screenshot I get from documentation, isn't it 8443 only used by ActiveGate or OneAgent?

Well, you can use both. You can also use the security gateway for accessing the API.
For Dynatrace Managed the 443 is just proxied by NGINX to the dynatrace server itself. It will also handle load-balancing in the cluster.
The 8443 is the dynatrace server process itself.

It is also possible to use the security gateway to call the Environment API.

Hi,
some quick clarification, port 8443 is used by Embedded ActiveGate.
