How do I get a Slack bot to import markdown?

Currently have a bot setup in Slack for a wordpress site(utilizing the slack plugin). Anytime someone makes a comment on the wordpress site the slack bot will post that comment in the channel specified. If someone comments on the wordpress site using markup, the bot will not transfer that markup, but instead push out the raw HTML.

Wordpress comment:

### Maintenance 

Desired Effect(and how it's coming out on wordpress):

Maintenance 2/22/2016

Slack bot's output:

<h3>Maintenance 2/22/2016</h3>

Has anyone found a workaround for this? Would be okay with integrating slack's markup into my comment fields(if that's possible) -- would like both the wordpress comment and slack comment be the same.

Let me know if I can clear up any confusion or elaborate on this issue.
