This page is meant as a one stop shop housing all resources for Jira Cloud automation.
If you didn't know this existed, you are in for a treat. Jira automation is a no-code automation engine available to every single Jira Cloud instance across all Jira products (There is also an app for Server folk). It allows you to automate endless tasks and processes, even across third party tools like Slack and GitHub.
While this is a new community space, Jira automation is not a new feature. There are tons of existing resources to help guide you as you start your automation journey. (It used to be an app called Automation for Jira by Code Barrel so don't be confused if you see this when looking through older posts).
