By default, there are two events that can be sent to Slack:
<ol>
<li>When a post needs review (status transitioned to ‘pending’)</li>
<li>When a post is published</li>
<li>When there’s a new comment</li>
</ol>
It’s possible to add more events using <code>slack_get_events</code> filter. For more information check <a href="http://gedex.web.id/wp-slack/" rel="nofollow ugc">the doc</a>.
Development of this plugin is done on <a href="https://github.com/gedex/wp-slack" rel="nofollow ugc">GitHub</a>. Pull requests are always welcome.
