idunbar_usf For what it's worth, we frequently run into the issue of the token expiring without us noticing. The token doesn't seem to be persisting beyond 30 days for us. I've gone through the documentation and steps a number of times and everything looks correct, but as I'm learning through this process, something seems to be a bit different with our installation. Not sure what though.
Anyway, we have a script that sends a test email to our system each week, and when we see that the ticket wasn't opened, we know we need to manually refresh the token. It means that there's a window of time where new tickets possibly aren't being submitted, but for our environment, a couple of days isn't a big deal.
