Hi,
I'm trying to retrieve the key from a created issue to fill a custom field in the trigger issue.
Trigger and Created issues are in different projects and are sub task types
Problem is that I need to branch it to retrieve data from the Created parent issue to gather the key of a previously created issue that will be the parent of the new one in a different project)

Trying so many ways API seems the direction but I get a 405 whenever i try to use smart values in the URL.
Any clues?
Thanks in advance
