OAuth success callback Problem

I'm able to complete a full OAuth cycle but in the end I receive this link

https://domain.org/auth/oauth2/success?project=XXXXX&key=a_session_XXXXXX&secret=XXXXXXXXXXXXXXXXXXXXXXXXXX

How to use this data to create a session? On my console I can see that session exists but account.GetSession("current") throws error that 'guest' has no access to 'accounts'
