Automation integrations with other Atlassian products - cross-product triggers and actions for Trello, Confluence and Jira

Suggested use cases

• There are some use cases where a cross-product triggers in Automation rules in Atlassian products. i.e. If a Jira Issue is mentioned by a Confluence page, a link is created in the Jira issue automatically, Automation should be able to use this "mentioned by" as a trigger
• Trello integration for automation, e.g. action to create Trello cards based on Jira issues status - I need to create a card on trello when specific Jira issue is marked as in progress & it has a pull request linked to it.
