Is it possible to have creating a sub-task as a trigger?

[Joe Milner-Smith]

I would like to have some automation created that when a sub-task is created it automatically changes the priority of the parent task to 'Blocked'. Is this possible?

Assuming you have blocked as a priority option (I do not). You would create the automation like this, when the issue is created ,and the issue type equals sub-task, for the parent of the subtask, you would then: edit the issue fields priority and select from the final screen "Blocked"

If you find my answer helpful, please accept it. If it does not please let me know and I can help you troubleshoot further.

Hi @Joe Milner-Smith 

I would use the issue created trigger, but then add conditions to match only the sub-task. From there you can add a branch for the parent and then an action to transition that issue.

Thank you, this worked well
