PowerShell Script to trigger Orchestrator Runbook

From time to time, I need to Trigger an Orchestrator Runbook via PowerShell and the WebService SCO offers. So I will walk you through all the steps, from creating the Runbook with Initialize Data, assigning the needed Permission, and writing the PowerShell Script.

The PowerShell Script

  • Will trigger the Runbook
  • Wait for a Complete Status
  • And Return the Result

Create the Orchstrator Runbook

The first step will be to create a Runbook with some Initialize Data, the Information we want to pass to the Runbook.

So I have created a Runbook with the Name “Test Runbook” and 1 Parameter

And I also added some Return Data

Grant Permission

Next, we need to grant Permission, so the User who wants to start the Orchestrator Runbook can do it.

Ensure that the User has the following Permissions on the Folder and Parent Folders, where the Runbook is stored.

PowerShell Script

We need some values to trigger the SCO Runbook, so we need the “Runbook ID” and the “Parameter ID.”

See my BlogPost for Details:

SQL Query to get Runbook and Parameter ID from SQL – System Center Orchestrator

Now see the Script and fill in the Details.

    $inputs = $XMLString.SelectNodes('//d:Name',$nsmgr)
   foreach ($parameter in $inputs){
      # Each 'Name' has related elements at the same level in XML

            $obValue = $elements.InnerText
        if (($Name -eq $obName) -and ($Direction -eq $obDirection)){

          #Return the Requested Property
         If ($DesiredData -eq "Id"){
            return $obId

    While($DoExit -ne "Yes")


# As the runbook is no longer active, query the Instance of the submitted job
$ResponseObject = invoke-webrequest -Uri "$($RunbookJobURL)/Instances" -method Get -UseDefaultCredentials
#Retrieve the Instance ID
$XML                = [xml] $ResponseObject
$RunbookInstanceURL = $XML.feed.entry.id
write-host "Runbook Instance URI " $RunbookInstanceURL
#The Instance can be used to retrieve the Parameters for the particular job
$ResponseObject                 = invoke-webrequest -Uri "$($RunbookInstanceURL)/Parameters" -method Get -UseDefaultCredentials 
[System.Xml.XmlDocument] $xml   = $ResponseObject.Content

#Make sure to mach the Return Name in your Runbook as second Parameter
# in our Example the Name is "Return"
$RunbookResult                   = GetScorchProperty $xml "Return" "Out" "Value"

write-host "Runbook Result " $RunbookResult

The Result looks like this.
