Hi Anthony. Thanks for the response.
Then I think that our only choice at this point would be to try with OAuth2. But, what I don't understand is how are we using OAuth2 for a Microservice. I mean, when I create the OAuth2 credentials, it requires me to select between one between: Android, Chrome App, IOS, TV and desktop App. My application is a *backend* microservice, so none of these matches with what I want. Also, when I prepare for verification the consent screen it requires me some staff focus in *my users*, when the only user I have, and the only user that will see this consent screen, is myself. Specially the Youtube video where I need to explain how will I use the scope in my app... It is totally focus in a front end application, which will have authorised users. What I am I suppose to record in this video, the Java code of my backend microservice? I don't know if I am missing something.
