Azure Automation offers to collaborate with each Runbooks as Workflok, and you can setup your simple workflow with following this article!

Create your new Runbook as "PowerShell"

Create your new "PowrShell" Runbook under your Azure Automation account and edit it like below. This Runbook output your Azure resources in a location specified by a parameter.

Param
(
    [Parameter (Mandatory = $true)]
    [String] $Location = 'Japan East'
)

# Setup Authentication
$Conn = Get-AutomationConnection -Name AzureRunAsConnection
Add-AzureRMAccount -ServicePrincipal -Tenant $Conn.TenantID -ApplicationId $Conn.ApplicationID -CertificateThumbprint $Conn.CertificateThumbprint

Get-AzureRmResourceGroup -Location $Location | ForEach-Object { Write-Output $_.ResourceGroupName }

You can specify parameters with "Param" keyword like above. "PowerShell Workflow" created in next section can call "PowerShell" Runbook, so you have to create your Runbooks as "PowerShell".

Create new Runbook as "PowerShell Workflow"

You can find how to pass your parameters and how to get output with your "PowerShell" Runbook.
