I'm attempting to unwind a fairly complicated process and determine how many missing records i have.  

I have a workflow that calls an API endpoint and even if the endpoint call returns a Failed result, the workflow shows as completed.

Consequently, I'm trying to find a report (or other way of getting to data) that shows a specific token in a specific workflow.  

See below.  

Is there anyway to get to this data so that i can search for all workflow instances where it does not ="Success"

Thank you for any pointers!
