PowerShell script to audit and export Channel content details of your Office 365 Stream

Following the previous script developed to audit Office 365 Video Portal:

• https://techcommunity.microsoft.com/t5/Office-365-Video/PowerShell-script-to-audit-and-export-all-content-details-of/m-p/352594#M830

I worked to retrieve something equivalent with Office 365 Stream.

There is not yet public API available into Office 365 Stream, MS communicated that API delivery Q2 or Q3 2019.

But O365 Stream portal (https://web.microsoftstream.com) is using internal API used into Stream internal pages like the following examples:

List of O365 Groups:

• Page: https://web.microsoftstream.com/browse?view=group
• API: https://euno-1.api.microsoftstream.com/api/groups?xxx

List of videos for one O365 Group:

• Page: https://web.microsoftstream.com/group/{groupid}?view=videos
• API: https://euno-1.api.microsoftstream.com/api/groups/{groupid}/videos?xxx

List of Channels

• Page: https://web.microsoftstream.com/browse?view=channel
• API: https://euno-1.api.microsoftstream.com/api/channels?xxx

Those API, giving results in JSON format, can be used only if you connect O365 Stream first to start your web session, and because that solution is only to wait official Public API, I decided to stay in that Web Browser usage mode.

The process to respect step by step (steps are placed into the PowerShell script):

1. Open O365 Stream Portal into your Web Browser (with your admin credentials)
   - https://web.microsoftstream.com/?NoSignUpCheck=1
2. With the same Web browser (other tab or other windows), open the following links:
   1. FROM 0 to 100: https://euno-1.api.microsoftstream.com/api/channels?$top=100&$orderby=metrics%2Fvideos%20desc&$expand=creator,group&api-version=1.3-private&$skip=0
   2. FROM 100 to 200: https://euno-1.api.microsoftstream.com/api/channels?$top=100&$orderby=metrics%2Fvideos%20desc&$expand=creator,group&api-version=1.3-private&$skip=100
   3. ... : Stop when you have no value into the page
3. Save each of that JSON Results into the work folder (C:\PSScript\ChannelsJSON\)
   1. channels100.json
   2. channels200.json
   3. …
4. PowerShell script will generate an Aggregated CSV file containing O365 Stream Channel details

Before execute the script, you have to set the parameters with the correct value (depending on total channels you have into your O365 Stream and where you place the PowerShell script):

• [int]$Loopnumber = 2    # << 2 indicates between 100 and 200 channels
• [string]$PowerShellScriptFolder = "C:\PSScript"

[string]$PowerShellScriptFolder = "C:\PSScript"
[string]$streamJSONfolder = Join-Path -Path $PowerShellScriptFolder -ChildPath "ChannelsJSON"
Remove-Item -path $streamJSONfolder\* -include *.json -Force -Recurse

[string]$StreamPortal = "https://web.microsoftstream.com/?NoSignUpCheck=1"
[string]$StreamPortalChannelRoot = "https://web.microsoftstream.com/channel/"
[string]$StreamAPIChannels100 = "https://euno-1.api.microsoftstream.com/api/channels?NoSignUpCheck=1&`$top=100&`$orderby=metrics%2Fvideos%20desc&`$expand=creator,group&api-version=1.3-private&`$skip="

[int]$Loopnumber = 2

You can use that solution as you want and modify it depending of your case and request.

Update March 22 2019:

Stream root URL used for Internal API can be different based on tenant region. I collected some URLs as much as I can (if you have anyone new, please to add it in comment to update that list)

• Europe: https://euno-1.api.microsoftstream.com
• Asia: https://aase-1.api.microsoftstream.com
