Hi Community,
I am keen to get feedback on options to integrate multiple ticketing solutions into a single ticketing system. The control I have is over the part of the process in the orange box.

I have set up a version of this. relying on the JSM Request Types, however, this only caters for the initial creation event, not subsequent Updates, which of course leads to duplicates being created each time a ticket is updated in the external ITSMs.
I assume I need to consider a mail handler, use of the JIRA API or a 3rd party tool?
Any input from the community is welcome.
Cheers
