Markdown doesn't work in attachments : <p>I'm creating a Slack integration with the Slack API. I followed <a href="https://api.slack.com/docs/formatting">the documentation</a> but the markdown formatting doesn't work on my attachments...</p>

<p>Here is my response object:</p>

<pre><code>{
  response_type: "in_channel",
  text: "List:",
  attachments: [
    { 
      text: "*pseudo*:\nbla bla bla",
      mrkdwn: true
    }
  ]
}
</code></pre>

<p>The "*" are displayed and not evaluated. Did I make a mistake? </p>
