2. Chatfuel will collect info (user's attributes) that user input and send to our rails app , in this case chatfuel-rails
3. chatfuel-rails grabs those attributes through rails params, then, process result and response to chatfuel via JSON response
4. It is possible to redirect to blocks dynamically, base on app logic.
