Uploading app icons for manage apps in intune using microsoft graph SDK Powershell

Question

hi all,&nbsp;I am creating a script to add apps to intune and assign them.&nbsp; currently, all is working well apart from uploading the icon.&nbsp; Here is the portion of the body parameters&nbsp;&nbsp;$appBody = @{&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; '@odata.type' &nbsp; &nbsp; &nbsp; &nbsp; = "#microsoft.graph.winGetApp"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; description &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = $appInfo.ShortDescription&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; developer &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = $appInfo.Publisher&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; displayName &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = "$($appInfo.packageName) ($($runAsScope))"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; informationUrl &nbsp; &nbsp; &nbsp; &nbsp;= $appInfo.PublisherSupportUrl&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; largeIcon &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = @{&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "@odata.type"= "#microsoft.graph.mimeContent"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "type" = "image/jpeg"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "value" = $base64string&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; installExperience &nbsp; &nbsp; = @{&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; runAsAccount = $runAsScope&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; isFeatured &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= $True&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; packageIdentifier &nbsp; &nbsp; = $appId&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; privacyInformationUrl = $appInfo.PrivacyUrl&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; publisher &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = $appInfo.publisher&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; repositoryType &nbsp; &nbsp; &nbsp; &nbsp;= "microsoftStore"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; roleScopeTagIds &nbsp; &nbsp; &nbsp; = @()&nbsp; &nbsp; &nbsp; &nbsp; } &nbsp;&nbsp;There are no errors&nbsp;i have tried type "image/png" as well, but again no errors.&nbsp; I am using the&nbsp;New-MgBetaDeviceAppManagementMobileApp command.&nbsp;&nbsp;&nbsp;I will try to manually use graph explorer to see if I can do it post app creation.&nbsp; Any pointers and examples welcomed

hi there, apologies for the delay. Firstly, with the above you are not using the MS Graph Powershell SDK. Which we want. Also, if you look at the code snippet, the image is in base64 value and put into the var $base64string. Although i maybe should of put that there to make it clearer.

IT seems that it does not upload the icon straight away when creating the app. we looked at other examples, and we can see that some are creating the app, and once finished, they then upload the image icon. Once we did this it seems to work. I cant find any documentation yet to see if this is the case. but we can live with that workaround

Suleyman Ali&nbsp;&nbsp;I'm working on something similar, used this blog post https://rozemuller.com/add-microsoft-store-app-with-icon-into-intune-automated/ for that. Basically you create a Base64 of it&nbsp;$imageUrl = "https://apps.microsoft.com/store/api/ProductsDetails/GetProductDetailsById/{0}?hl=en-US&amp;gl=US" -f $exactApp.PackageIdentifier
$image = Invoke-RestMethod -Uri $imageUrl -Method GET
$wc = New-Object System.Net.WebClient
$wc.DownloadFile($image.IconUrl, "./temp.jpg")
$base64string = [Convert]::ToBase64String([IO.File]::ReadAllBytes('./temp.jpg'))&nbsp;and use that as icon like this, type should be string:&nbsp;$deployUrl = "https://graph.microsoft.com/beta/deviceAppManagement/mobileApps"
$appBody = @{
    '@odata.type'         = "#microsoft.graph.winGetApp"
    description           = $appInfo.ShortDescription
    developer             = $appInfo.Publisher
    displayName           = $appInfo.packageName
    informationUrl        = $appInfo.PublisherSupportUrl
    largeIcon             = @{
        "@odata.type"= "#microsoft.graph.mimeContent"
        type = "String"
        value = $base64string 
    }
    installExperience     = @{
        runAsAccount = $appInstaller.scope
    }
    isFeatured            = $false
    packageIdentifier     = $appId
    privacyInformationUrl = $appInfo.PrivacyUrl
    publisher             = $appInfo.publisher
    repositoryType        = "microsoftStore"
    roleScopeTagIds       = @()
} | ConvertTo-Json 
$appDeploy = Invoke-RestMethod -uri $deployUrl -Method POST -Headers $authHeader -Body $appBody&nbsp;

Did that work out for you?

Ok, like a two-stage thing and not possible in one run? I couldn't find anything about that either. I'm curious about that let us know if you find anything
