Re: REST web service APIs

I am talking about what happens *AFTER* user authentication. The successful authentication gets you the token. All requests after that check that token.

Of course there is a difference between authentication and authorization. You can do authorization the same way. Check the authority on each authenticated request and send back the proper HTTP response code.

Thanks,
Todd

You're talking about user authentication. That's just the first step.
Authentication gets you through the front door. It lets you talk to the web service provider, but not necessarily to invoke APIs. For that, I was suggesting that the service check the "authority" of the user to invoke individual APIs. The web-service could look that up in a list (i.e. query a table).

At any rate, do you see the difference between "authentication" and "authority"?
