Past zoom rooms check-ins/outs, reservations

Hi,
we are interested in doing some reporting / analytics on zoom rooms usage, mostly: check-ins, check-outs, reservations created/updated/deleted.
I see that data is available via webhooks, like
workspace.reservation_checked_in, zoomroom.checked_in workspace.reservation_created,
but would like to know if there is an API for accessing similar data, as we are interested in past data, or if there are plan to release it soon.

Also, what’s the difference between workspace.reservation_checked_in and zoomroom.checked_in. It seems in some cases worskpace and room are used interchangeably, is zoomroom a subset of the workspace?
