Scriptrunner and Confluence Questions Listener

[James Hunt _Ascend_]

We are looking into integrating Mattermost with Questions for Confluence and cannot seem to figure out the entry point to make a listener trigger when a Question is asked. 

We've already been able to integrate through the REST API, but would rather that Scriptrunner fire a webhook like call outbound to a Mattermost channel when a new Question is asked.

Thoughts?
