The startDate and endDate parameters you’re seeing in the Members page URL are probably being carried over from the Analytics page – they don’t have any effect on the Members page. Not breaking anything, but probably something we should fix!
For on-demand usage across different time periods, your best bet is the Usage page. It has a date selector and supports from and to query parameters in the URL. From there, you can export a CSV for further data manipulation.
afaik I see, there is no finance csv export on the Analytics page. So an export that gives me an overview of the included, free and on-demand usage for a given timeframe per user is there not available. Correct?
Maybe possible the generate it based on /dashboard/usage, but a bit more complex.
It think it should be a good idea to add time filters on the Members page.
