How do I access KPIs via REST API?

[Scott Doughty]

I'm working on an integration project which requires extracting data from JIRA and loading into another system. I have successfully loaded task and comment data using the REST API (e.g. calling https://redacted.atlassian.net/rest/api/2/issue/JP-1/comment to retrieve comments) but now I am being asked to retrieve KPIs. Can anyone recommend a way to go about this?

Thanks

Scott

P.S. at the moment I have nothing more by way of a specification than "retrieve KPIs" so if you have links to helpful information about how KPIs are defined or questions I should be asking please share them.
