title: How to get the Slack DM channel ID of the Slack App
body: <p>I have created a simple Slack App app where the only purpose is to send a message to a channel. I understand that there is the <code>conversations.list</code> API to list all public channels to get the correct ID.</p>
  <p>However, as a first step, I just want to send the message to the app channel itself. If I use the D... ID it works as expected. No invite by the channel is needed. But how do I get this ID? <code>conversations.list</code> only returns publich channels, but no the app channel itself.</p>
