(intro)
I am new to Google Cloud Endpoints and I have started to build some HTTP REST services.
The purpose of those services is to be consumed directly by the users of my application (Business to Consumer - not business to business).
(The question)
I need to secure my services in a way to have only registered users being able to retrieve sensible data (and after login). My main purpose is to have the list of registered users saved in my database on CloudSQL (Dont want to use FB of Google Accounts). I was not able to find particular information about this point in the official Google documentation regarding authentication.
Can anyone advise me of the way to proceed and suggest some tutorials?
Thank you in advance.
