I setup an automation in our service management project with the intention of automatically routing tickets to a separate project. Since users copied on the emails are added to the ticket as a requested participant automatically this seems like a logical approach.
Trigger: When: Issue Updated
Condition: Request participants contains any of
Action: Create a new ticket in the different project
And: Link issue to most recently created issue.
I used the Issue updated trigger because it's my understanding that Jira creating the ticket then adding the requested participants from the email are two separate actions. When testing the process the only feedback the audit log send is no action was performed because the ticket did not meet the conditions even though the tickets are successfully being created with the correct request participants in the service management project.
