title: Send a message in a channel "only visible to you"
body: <p>I can not see in the slack API documentation the way for a bot to send a message in a channel that response to a user.</p>
  
  <p>The same way <code>slackbot</code> does reply when doing <code>/help</code>.</p>
  
  <p>Anyone can let me know if that is possible?</p>

  <p>Notice the "Only visible to you". In the RTM manual they say that the messsage is of the same type as the event <a href="https://api.slack.com/events/message" rel="noreferrer">message</a>.  I don't see any attributes that would say it is visible only to a certain user.</p>
