API and/or PowerShell for managing MS Stream

Sorry for not responding in a while. We've been heads down getting live events ready and I've not be free to answer here. The first response to your post is still accurate. 

We currently do not have any Stream APIs or powershell cmdlets. 

There isn't a way to get stats out of Stream programmatically.

The only thing that *might* help you is that we do send an audit log event each time a video is viewed to the O365 Audit log. They do have APIs, so I believe you could use the O365 Audit log APIs to pull out the events corresponding to when a person viewed a video.

We are in the process of getting started in earnest on both analytics for videos in Stream and Public REST APIs. We can make sure that when we do both of those projects that the new video level stats we build is exposed via the new public REST APIs we will be building.
