The number of entries to return per page. The maximum range of valid page sizes is documented with minimum and maximum values, but the range might be further limited dynamically based on the requested information, account, and system status. Values outside of the (dynamic) allowed range will not result in an error, but will be clamped to the nearest limit. Thus, logic to detect the last page should not be based on comparing the requested size with the received size, but on the existence of a nextPageToken value.
