I have hosted a web service on App engine cloud endpoint. The APIs are protected by Auth2.0 as google say but for google accounts. What I want to achieve is allow these APIs to be accessed using 3rd party tokens. Lets say I have my on Authentication server also providing User Management. I want my google endpoint APIs to be access based on the 3rd party token I provide at the time of API call.
- Is this possible?
- If Yes, Where should I write the mechanism to verify the clients authenticity and hint of how its to be done.
- Also is there any demo project available that provides user management and authentication server and returns a token that can be accepted by App Engine.
