    So your script doesn't work? What are the symptoms? What are the error messages? Please edit the question to include this vital information. – DavidPostill Jul 12 at 19:48

Perhaps you should send the Authorization header yourself, like this (untested) code:

$uri = "{url here}"
$username = "{username here}"
$password = "{password here}"
$b = [System.Text.Encoding]::UTF8.GetBytes($username + ":" + $password)
$p = [System.Convert]::ToBase64String($b)
$creds = "Basic " + $p
Invoke-WebRequest -Uri $uri -Method Get -Headers @{"Accept" = "*/*"; "Authorization" = $creds}
