The Report Run object represents an instance of a report type generated with specific run parameters. Once the object is created, Stripe begins processing the report. When the report has finished running, it will give you a reference to a file where you can retrieve your results. For an overview, see API Access to Reports.
Note that certain report types can only be run based on your live-mode data (not test-mode data), and will error when queried without a <a href="https://stripe.com/docs/keys#test-live-modes”>live-mode API key.
