Rule set for API endpoints

Question that someone asked me and I’m not sure about the response. Does it make sense to use the same rules set for a Website and for API endpoints by using the dashboard intended for websites only, or is it better to setup specific rules for the api endpoints by using API Shield service? It seems they are using the same rule set for the site and for the api related and now it needs to know if it is better continue with this approach or use a different one for each of them.

Thank you.
