What parameter is NOT required to run a report using the Stripe API?

In the context of generating reports with the Stripe API, certain parameters are essential for the successful execution of a reporting request. The parameters "interval_start" and "interval_end" are crucial as they define the time range for the report; these dates specify the start and end of the reporting period. Additionally, the "report_type" parameter is necessary because it indicates the specific type of report that needs to be generated.

The "currency" parameter, however, is not a required parameter. While reports could be generated in specific currencies, it's not strictly needed to run the report itself. This means that developers can execute reports without specifying the currency, which allows for greater flexibility, especially when dealing with multiple currencies within their transactions. Hence, the need for the other parameters makes the selection of "currency" as the non-required parameter correct.
