Hi kcelmer

I did play around a little bit with Interactive Permissions (like in your example).
I was not able to add or remove a Follower (other than my own user)

###############################################################################
# Connect with MgGraph Interactive
###############################################################################
Connect-MgGraph -Scopes "Sites.ReadWrite.All","User.Read.All" -NoWelcome

#Get User
$UPN = "email address removed for privacy reasons"
$User = Get-MgUser -UserId $UPN
Write-Host "UserID: $($user.id)" -ForegroundColor Cyan

#Details of SharePoint Site
$SiteURL = "https://icewolfch.sharepoint.com/sites/DemoPrivate"
$Domain = ([System.Uri]$SiteURL).Host
Write-Host "Domain: $Domain" -ForegroundColor Cyan
$AbsolutePath = ([System.Uri]$SiteURL).AbsolutePath.split("/")[2]
Write-Host "$AbsolutePath" -ForegroundColor Cyan
$uriSite = [string]::Format('https://graph.microsoft.com/v1.0/sites/{0}:{1}',$Domain,$AbsolutePath)
$Site = Invoke-MgGraphRequest -Method GET $uriSite
Write-Host "SiteID: $($site.id)" -ForegroundColor Cyan

#Create Body for Add/Remove
$params = @{
	value = @(
		@{
			id = $Site.ID
		}
	)
}

#Create Body for Add/Remove
$params = @{
	value = @(
		@{
			id = $Site.ID
		}
	)
}

#Add Follower
Write-Host "Add Follower to Site: $($Site.Id)" -ForegroundColor Cyan
Add-MgUserFollowedSite -UserId $user.Id -BodyParameter $params

#Remove Follower
Write-Host "Remove Follower to Site: $($Site.Id)" -ForegroundColor Cyan
Remove-MgUserFollowedSite -UserId $user.Id -BodyParameter $params

Tried with an Entra App and Certificate for Authentication.

Be aware that List followed sites is not Supported with Application Permissions

#Add Follower

Add-MgUserFollowedSite -UserId $user.Id -BodyParameter $params


#Remove Follower
Write-Host "Remove Follower to Site: $($Site.Id)" -ForegroundColor Cyan
Remove-MgUserFollowedSite -UserId $user.Id -BodyParameter $params

Hope that helps.

Thank you Andres! It looks like you put considerable effort into this. Just to clarify, were you able to follow a site for a user with the Entra/certificate approach?

Hi kcelmer

I found an error in the code

The Graph Endpoint sites only returns the "Team site (classic experience)"

https://graph.microsoft.com/v1.0/sites/<tenant>.sharepoint.com

If you use the following command you get the Websites with the ID's

Get-MgSite | where {$_.DisplayName -match "demo"}
Get-MgSite | where {$_.DisplayName -eq "IcewolfDemo"}

###############################################################################
# Connect with Entra Application
###############################################################################
# Application Permissions
# - Sites.ReadWrite.All
# - User.ReadBasic.All
###############################################################################
$AppID = "2f79c9c9-4024-4d46-a06f-67c1f2d92b02"
$TenantID = "icewolfch.onmicrosoft.com"
$CertThumbprint = "A3A07A3C2C109303CCCB011B10141A020C8AFDA3"
Connect-MgGraph -AppId $AppID -TenantId $TenantID -CertificateThumbprint $CertThumbprint -NoWelcome

#Get User
$UPN = "email address removed for privacy reasons"
$User = Get-MgUser -UserId $UPN
Write-Host "UserID: $($user.id)" -ForegroundColor Cyan

$SiteID = "icewolfch.sharepoint.com,e5167e43-7495-4611-b74c-bbf2ffd85ce5,0c772746-d2d9-4c13-8176-bd41df1b7a6e" #IcewolfDemo

#Create Body for Add/Remove
$params = @{
	value = @(
		@{
			id = $SiteID
		}
	)
}

#Add Follower
Write-Host "Add Follower to Site: $($Site.Id)" -ForegroundColor Cyan
Add-MgUserFollowedSite -UserId $user.Id -BodyParameter $params

#Remove Follower
#Write-Host "Remove Follower to Site: $($Site.Id)" -ForegroundColor Cyan
#Remove-MgUserFollowedSite -UserId $user.Id -BodyParameter $params

The Graph Query on the User is updated
https://graph.microsoft.com/v1.0/users/<userprincipalname>/followedSites

And the Followed Sites in SharePoint is reflecting that (takes a few Minutes until that's visible here)

So yes, it works but you have to figure out the SiteID and use that as a Parameter.

Kind Regards
Andres
