title: ChatBot QnaMaker(Microsoft Azure) vs Lex (Amazon AWS)
body: <p>Looking to make a chatbot on either Microsoft QnaMaker or Lex. </p>
  
  <p>I would like to be able to make API calls to request answer to the question (node.js), train the bot using the API.
  Currently I am using QnaMaker but unfortunately it doesn't seem to have response cards where user can click on it.  </p>
  
  <p>I know that Amaazon Lex allows this but do they allow training of bot through API?</p>
