title: Multiple Responses with Dialogflow (aka Api.ai)
body: <p>I'm trying to create a chatbot which once "greetings" process is done goes on and initiate a new topic without any user query. It has to be something like the following:</p>
  
  <p>bot : hello</p>
  
  <p>user : hello</p>
  
  <p>bot : how old are you?</p>
  
  <p>user : 35</p>
  
  <p>bot : Great.</p>
  
  <p>bot : Let's talk about politics. Are you american?</p>
  
  <p>Until the "great" line everything works but then I cannot trigger the event that will prompt the line "Let's talk about politics...."</p>
  
  <p>The doc is vague, can I do this without webhooks? And if not, how would a webhook like this look like?</p>
