Slack seems to be growing quickly in popularity. We have had several requests for Slack integration recently.
We are working on some infrastructure within Aha! to support sending an event stream to group chat programs like Hipchat and Slack.
I will add you to the feature request and let you know when it is available.
Has there been an update on this yet, has Slack been integrated?
Yes, the Slack integration was released about a year ago. You can read about it here: http://support.aha.io/hc/en-us/articles/201243639-Integrate-with-Slack
You won't be notified about changes to this idea.
