Software Installation Using Azure Policy State Change Events

AnthonyWatherston  I made modification to the  initial block, the challenge happens to be the fact that  I can't even get the event to trigger for compliance. It's inaccurately reporting those resources as compliant

I have manually installed the application to make sure the value I'm providing to the unique field is correct.  I might be missing something on that end.

All things equal, the windows side of thing works just fine.

Param([object]$WebhookData)

$eventData = (ConvertFrom-Json -InputObject $WebhookData.RequestBody)

if ($eventData.subject -match 'microsoft.compute/virtualmachines') {
    $vmName = $eventData.subject.Split('/')[8]
    $vmResourceGroupName = $eventData.subject.Split('/')[4]
