ruby on rails - API authorization -


please forgive me if question has been asked/answered somewhere else. i've been researching while , haven't found answer yet.

i have api needs serve (at least) 2 different types of consumers different needs , privileges. i'm of course talking concept of authorization, well-worn territory within web apps. but, strangely, googling "api authorization" or "api acl" doesn't bring find meaningful.

so question is: how handle authorization (not authentication) when writing api?

i think answer answered in technology-agnostic way, if helps, i'm using rails.
