Hi, I’m Marion. I lead one of the SRE teams for a service called IBM App Connect. I created a templated integration between PagerDuty and Slack to manage updates to Slack groups and topics based on a PagerDuty schedule. Why not check it out and give App Connect a try: https://developer.ibm.com/integration/blog/2017/11/03/accelerate-flow-creation-templates-ibm-app-connect/
Hi Marion! Welcome to the PagerDuty Community!
Thanks for sharing your slick integration - hoping this comment will pop it up and get some extra on it.
