Upload-WindowsAutopilotDeviceInfo - how to use client ID and secret?

[silicondt]

I am trying to use the latest version of Upload-WindowsAutopilotDeviceInfo (1.2.1)

The notes say "1.2.1 - (2023-06-07) Improved access token retrieval, now supports client credentials flow using ClientID and ClientSecret parameters"

Yet when I run the script and pass a CLIENT ID and a CLIENT secret from an azure app I made, it still pops up with a username and password prompt. What am I doing wrong?

Is there any guidance to how to create the enterprise app to work right? What permissions should be turned on in the app?

Example of code I tried.. but it still asks for a username and password.

Install-Script -Name Upload-WindowsAutopilotDeviceInfo -force -confirm:$false -Scope "AllUsers"

$tenant = "mydomain.com"
$ClientID = "12sdsdsdsd-ffff-ssss-eeee-dsfsdfsdfsdf"
$Clientsecret = "blablablabla"

cd "$env:ProgramFiles\WindowsPowerShell\Scripts"
./Upload-WindowsAutopilotDeviceInfo -TenantName $tenant -ClientID $clientID -ClientSecret $clientsecret

So after testing is seems like this part of your script is the issue.

# Construct table with common parameter input for Get-AccessToken function
$AccessTokenArguments = @{
    "TenantId" = $TenantID
    "ClientId" = $ClientID
    "RedirectUri" = $RedirectUri
    "ErrorAction" = "Stop"
}

**************** This part below does not add the secret to the $AccessTokenArguments variable, even if it was passed to the script **************** Also if the secret is ConvertTo-SecureString it comes back as an error the secret is wrong. If its passed without converting it, it works OK. I tested this my manually putting it in the $AccessTokenArguments and commenting out the below part ****************

# Dynamically add parameter input for Get-MsalToken based on parameter set name
switch ($PSCmdlet.ParameterSetName) {
    "ClientSecret" {
        Write-Verbose "Using clientSecret"
        $AccessTokenArguments.Add("ClientSecret", $(ConvertTo-SecureString -String $ClientSecret -AsPlainText -Force))
    }
}
