I am trying to use the swagger online editor http://editor.swagger.io/#/ There is a button called Authorize that opens a dialog where you can provide method of authorization. There are two options The first is for OAuth2 and the second is for API-Key. I can't figure out how to use these. For OAuth2 authorization, a client ID is required.How does one get a client id? For api-key authorization, the editor provides a key called special-key. When I make an API call even without special-key in postman, the API returns a valid response. Is this because the implementation work without keys too?
