Thanks Ryan for great post. This railscast give me the most valuable 9$ per month :)
I always have this error when I follow this tutorial:
OAuth2::Error: invalid_grant: The provided authorization grant is invalid, expired, revoked, does not match the redirection URI used in the authorization request, or was issued to another client.
when I'm in the phase of parsing token. What is the problem and how I can fix this ?
