 Start the process by requesting a token

 When user returns create an access_token
 
   hash = { oauth_token: session[:token], oauth_token_secret: session[:token_secret]}
-  request_token  = OAuth::RequestToken.from_hash(@consumer, hash)
-  @access_token = @request_token.get_access_token

   # For 3-legged authorization, flow oauth_verifier is passed as param in callback
-  # @access_token = @request_token.get_access_token(oauth_verifier: params[:oauth_verifier]) 
-  @photos = @access_token.get('/photos.xml')
+  # access_token = request_token.get_access_token(oauth_verifier: params[:oauth_verifier]) 
+  @photos = access_token.get('/photos.xml')
 
 Now that you have an access token, you can use Typhoeus to interact with the OAuth provider if you choose.
