Azure Start/Stop VM via webhook - azure

Question

We have multiple VM's in our azure environment with multiple resourcegroups. Some of the resourcegroups have multiple VM's. We are now using an URL triggers webhook that will start or stop VM's. This is working, but when a resourcegroup contains multiple VM's all the VM's will start or all the VM's will stop instead of the one you want to start/stop.
Tried multiple scripts but it's isn't working or give me errors.
param(
[Parameter(Mandatory=$false)]
[object]
$WebHookData
)
write output "Data WebHook $WebHookData"
#retrieve ResourceGroup
$ResourceGroupName = $WebHookData.RequestBody
write output "Data ResourceGroup $ResourceGroupName"
$Conn = Get-AutomationConnection -Name AzureRunAsConnection
Connect-AzureRmAccount -ServicePrincipal -Tenant $Conn.TenantID -ApplicationId $Conn.ApplicationID -CertificateThumbprint $Conn.CertificateThumbprint
$VMs = Get-AzureRmVM -ResourceGroupName $ResourceGroupName
if(!$VMs)
{
Write-Output -InputObject 'No VMs were found in the specified Resource Group.'
}
else
{
ForEach ($VM in $VMs)
{
$StartVM = Stop-AzureRmVM -ResourceGroupName $ResourceGroupName -Name $VM.Name -Force #-ErrorAction SilentlyContinue
}
}
$message = ConvertTo-Json -Compress -InputObject ([ordered]#{
headers = #{'content-type' = 'text/plain'}
body = ''
statusCode = 200
})

You could try below script for Start/Stop Virtual machine.
Start VM
$connectionName = "AzureRunAsConnection"
$servicePrincipalConnection = Get-AutomationConnection -Name $connectionName
$null = Add-AzureRmAccount -ServicePrincipal -TenantId $servicePrincipalConnection.TenantId -ApplicationId $servicePrincipalConnection.ApplicationId -CertificateThumbprint $servicePrincipalConnection.CertificateThumbprint
$VMs = Get-AzureRmResource|Where-Object {$_.Tags.Keys -eq "owner" -and $_.Tags.Values -eq "daneum"}
foreach ($VM in $VMs) {
if ($VM.ResourceType -eq "Microsoft.Compute/virtualMachines") {
Start-AzureRmVM -ResourceGroupName $VM.ResourceGroupName -Name $VM.Name -Verbose
}
}
Stop VM
$connectionName = "AzureRunAsConnection"
$servicePrincipalConnection = Get-AutomationConnection -Name $connectionName
$null = Add-AzureRmAccount -ServicePrincipal -TenantId $servicePrincipalConnection.TenantId -ApplicationId $servicePrincipalConnection.ApplicationId -CertificateThumbprint $servicePrincipalConnection.CertificateThumbprint
$VMs = Get-AzureRmResource|Where-Object {$_.Tags.Keys -eq "owner" -and $_.Tags.Values -eq "daneum"}
foreach ($VM in $VMs) {
if ($VM.ResourceType -eq "Microsoft.Compute/virtualMachines") {
Stop-AzureRmVM -ResourceGroupName $VM.ResourceGroupName -Name $VM.Name -Force -Verbose
}
}
