Thank you for your reply.
This API (Get Network Clients) returns clients that have used this network for specific timestamp.
For example, if timestamp=86400 API call, returns clients for last 24 hours, whereas, i search a way to fetch data for specif day (from t0=2020-10-03T21:00:00Z and t1=2020-10-04T20:59:59Z).
Do you have any idea how to fetch this data?
