Hi William,
I can't speak for the OP, but where I see value in an integration is to be able to refer to epics, features, user stories, and/or tasks within Mattermost. The integration could pull summary information for the referenced object, and allow the user to click through to the detailed information within CA Agile Central. Another integration possibility is to show specific status changes for an object such as being moved to completed or blocked; we do something similar for our source control, builds, and deployments. Our current integrations for Git, Jenkins, etc. are available as standard offerings within Mattermost.
Thanks,
Jeremy
