I successfully authenticate and obtain a Token from my Owin TokenEnpoint (Katana implementation), but when i then call let's say.. my Java Api I would like to validate the issued Token.
So I would like to be able to call my Owin endpoint and just validate my Token, without authenticating again.
Facebook or Google provide something like:
https://graph.facebook.com/debug_token?input_token={0}&access_token={1} https://www.googleapis.com/oauth2/v1/tokeninfo?access_token={0}
