Is there any OO content available related to Slack/ChatOps integration ?
We've recently published an OO ChatBot that can integrate with Slack as well as additional collaboration tools.
You can download it here: https://marketplace.microfocus.com/itom/content/oo-chatops
I guess you are looking to trigger an OO flow and take some actions in Slack: post a message in a chat channel, instant message or similar stuff.
As Lucian mentioned earlier: it will be great to understand more about the exact usecase.
Slack has a rich API and many things could be covered on top of that.
I personally started to construct cloudslang based integration with Slack around post messaging. That could be subject to a publish/release under the github.com/CloudSlang. Still more about your use-cases would help.
