Seems like one of the first things that Jira should support is running an automation rule from a transition, but I can't seem to figure out how to do it.
I believe that I could do it the following way, but it seems like a total hack:
1) Create an automation rule which is triggered from an external webhook
2) Add a webhook to our system that points to the automation rules webhook
3) In the post function of the transition, run an "external webhook", which just points to our automation webhook. I'm not sure if the hooks are compatible though.
Thoughts?
