By trade I'm a Database Dev and haven't done much API work. I need to access Issue Key, two date fields (begin of in progress, date of when put into "Done"), and another custom field we created.
I need JQL can get me all the issues that are completed/done but to get the actual dates for status changes I need to hit the API.
I cannot use the db layer. This will run once a week and I will import into a on-premise db and put a BI tool we have access to on top.
