During SharePoint Online discussion a question popped up “How to get all installed application information in SharePoint Online?” a simple answer is Get-SPOAppInfo cmdlet! But, wait we are partially correct but read this documentation https://technet.microsoft.com/en-us/library/fp161398.aspx. The below image illustrates the parameters of Get-SPOAppInfo both set to be false and it’s not $TRUE – This cmdlet needs either Name or Product ID! So, we can’t use this cmdlet to retrieve all the apps installed in the given Tenant!

Issue:

So we can Get installed apps information by using below

Enough! We are not going to use this. Let’s use Client Side Object Model in PowerShell and solve the issue.

Output

Code:

Import-Module C:\SPPowerKit\Microsoft.SharePoint.Client.dll
Import-Module C:\SPPowerKit\Microsoft.SharePoint.Client.Runtime.dll
#Import-Module C:\SPPowerKit\Microsoft.SharePoint.Client.UserProfiles.dll
Import-Module C:\SPPowerKit\Microsoft.Online.SharePoint.Client.Tenant.dll
function Get-SPOAppInformation
{
    param(
    [Parameter(Mandatory=$true)]
    [string]$SPOUrl,

    [Parameter(Mandatory=$true)]
    [System.Management.Automation.CredentialAttribute()]$SPOCredential
    )

    $ClientContext = [Microsoft.SharePoint.Client.ClientContext]::new($SPOUrl)
    $ClientContext.Credentials = [Microsoft.SharePoint.Client.SharePointOnlineCredentials]::new($SPOCredential.UserName,$SPOCredential.Password)
    $Tenant = New-Object Microsoft.Online.SharePoint.TenantAdministration.Tenant -ArgumentList $ClientContext
    $Tenant.Context.Load($Tenant)
    $Tenant.Context.ExecuteQuery()
    $Appinfo = $Tenant.GetAppInfoByName([string]::Empty)
    $Tenant.Context.Load($Appinfo)
    $Tenant.Context.ExecuteQuery()
    $Appinfo
    $ClientContext.Dispose()
}

Get-SPOAppInformation -SPOUrl "https://contoso-admin.sharepoint.com" -SPOCredential "TenantAdmin@contoso.onmicrosoft.com"

Bit more to organize it, we can use PSObject!

Import-Module C:\SPPowerKit\Microsoft.SharePoint.Client.dll
Import-Module C:\SPPowerKit\Microsoft.SharePoint.Client.Runtime.dll
#Import-Module C:\SPPowerKit\Microsoft.SharePoint.Client.UserProfiles.dll
Import-Module C:\SPPowerKit\Microsoft.Online.SharePoint.Client.Tenant.dll
function Get-SPOAppInformation
{
    param(
    [Parameter(Mandatory=$true)]
    [string]$SPOUrl,

    [Parameter(Mandatory=$true)]
    [System.Management.Automation.CredentialAttribute()]$SPOCredential
    )

    $ClientContext = [Microsoft.SharePoint.Client.ClientContext]::new($SPOUrl)
    $ClientContext.Credentials = [Microsoft.SharePoint.Client.SharePointOnlineCredentials]::new($SPOCredential.UserName,$SPOCredential.Password)
    $Tenant = New-Object Microsoft.Online.SharePoint.TenantAdministration.Tenant -ArgumentList $ClientContext
    $Tenant.Context.Load($Tenant)
    $Tenant.Context.ExecuteQuery()
    $Appinfocollection = $Tenant.GetAppInfoByName([string]::Empty)
    $Tenant.Context.Load($Appinfocollection)
    $Tenant.Context.ExecuteQuery()
    foreach($Apps in $Appinfocollection)
    {
        $Results = New-Object psobject -Property ([Ordered]@{
        Name = $Apps.Name
        ProductID = $Apps.ProductID
        Source = $Apps.Source
        })
        $Results
    }
    $ClientContext.Dispose()
}

Get-SPOAppInformation -SPOUrl "https://contoso-admin.sharepoint.com" -SPOCredential "TenantAdmin@contoso.onmicrosoft.com"
