Answer 1

In APIM, when you select "I have existing API", that means you already have a swagger document for the API. If that's not what you want (i.e. you don't have a swagger doc), you can proceed with Create New API option.

Edit: What do you mean by an existing API here? Are you just having a service which needs to be exposed as a manage service? If yes, Create New API is the way to proceed.
