title: Changing Slack bot name / image using Slash Commands?
body: <p>I'm setting up a slackbot with slash commands and according to API you're able to pass username to set the username of a bot. When I try it, the name does not update. Does this not work with slash commands in the same way that it does with bots?</p>
  
  <pre><code>from bottle import run, post, request
  @post('/hello')
  def hello():
      mydict = request.forms.get('text')
      response = {
      "username": "test",
      "response_type": "in_channel",
      "text": "Greetings!"
          }
      return response
  </code></pre>

  /hello</p>
  
  <p>MyBot APP [11:00 AM]
  Greetings!</p>
