Usage stats API access problem

[Leszek]

Hi, 

I need to access Usage statistics data for an app. It available from Mange->Monitor->Usage Statistics page in the app itself, but I want to get it from other app via API. It serves following data:

AppId, UserId, ActivityDate, TotalEvents, TotalDuration, ActivityPureDate

So very useful for tracking app and user activity.
It is served by https://eu.appsheet.com/api/template/{appId}/stats endpoint but I can't figure out how to authenticate/authorize to get access to it. It is accessible from the browser if I am logged in into AppSheet, but in any other case I always get HTTP ERROR 401 (Unauthorized).

I've tried lots of ways to try authenticate using API Key both from account settings and IN: from cloud services to your app. Tried GET, POST, key in URL, in headers, etc. Different parameter names too. I can access app API starting https://eu.appsheet.com/api/v2/apps/ like described in docs, but this won't work with stats endpoint. 

Can anybody help me with that, please?

Thank you for the answer. I've seen those. I've done my research and tests before asking a question.
Data gathered in mentioned links are more general, platform/billing level. different from data provided by https://eu.appsheet.com/api/template/{appId}/stats which are one app focused and show how app is used. That's what I'm pursuing.
