When a Jira issue is transitioned I'd like to add a label to a GitHub pull request.
It seems all the integration between Jira and GitHub is in the opposite direction. I can update a Jira issue when an action is performed on GitHub (e.g. PR merged) but I haven't found a way to do an outgoing request from Jira to GitHub.
It's probably possible to use a Jira automation to make a request to the GitHub API but I'm hoping there is a simpler way.
