JIRA administrators often need to implement sophisticated workflows that go beyond the built-in capabilities of JIRA. The JIRA Misc Workflow Extensions add-on for Cloud provides extensions that help you to design advanced workflows.
The add-on provides advanced Post-functions to achieve this purpose with no programming skills. You can tailor your JIRA workflows to meet your need and reduce the user intervention on actions.
