After you create a webhook for the StopVM Runbook you can use the following PowerShell snippet to invoke your Runbook via the webhook.

This example would shutdown two VMs named web1 and web2 in the "webservers" resource group:

`$uri = "https://s4events.azure-automation.net/webhooks?token="

$vms = @(
@{ Name="web1";ResourceGroup="webservers"},
@{ Name="web2";ResourceGroup="webservers"}
)

$body = ConvertTo-Json -InputObject $vms
$header = @{ message="Started by CloudSkills.io"}

Invoke-WebRequest -Method Post -Uri $uri -Body $body -Headers $header`
