How can I catch a transition with Script Listeners?  
In the listeners I just found ‘Issue Created’ and ‘Issue Updated’, I’m guessing that the Event I need is ‘Issue Updated’, but this event can be triggered when the user updates a field, transition, or change the assignee, etc.  
My question here is if there’s a way to filter all Update events but ‘Transition’.

Hi @DanAlonso14 , probably you will need to use the changelog object, that is inside the event, as you can see [here](https://library.adaptavist.com/entity/change-epic-status-field-when-resolution-gets-set), you can find in the changelog list by field name, in your case you will need to use the state field.

Thanks, Ivan.
