Get user details over oAuth from C4C

hi,

I am trying to

1. get oAuth tokenn of enduser to make api calls to SAP C4C to get his details
2. I am comfortable with java and found the link: venkyvb/OAuthSAMLClient · GitHub to make api calls.

however the link above tells to configure oAuth IDP and oAuth Client. I am finding it difficult to figure this out. I am given an instance and I was told that i have administration role in it. However I couldnt find a way to configure oAuth IDP and oAuth client (like couldnt find the adminstration work centre in the instance). Now am i missing something? (attachment)

I have another userid and pwd which is supposed to have 'S' user role (with a diff website address) now logging here doesnt help either. Can somebody help me please? I am kind of stuck badly here!

Thanks,

Ravi
