How to fetch the entire list of active members at once?

Hi,

I've been through the documentation and fiddled with your test API, however I'm unsure which endpoint I should use and how I can filter by the member status (PartyStatusData.PartyStatusId) and get only the active ones.

Additionally, how can I get each member's matching User? Do I need to query the https://testapi.imis.com/Asi.Scheduler_SDKDemo/api/User endpoint instead?

Lastly, can do all members have a corresponding User record or can a member exist without User login credentials?

Thank you
