To Start SPD/Nintex Workflow through PowerShell Script.
In this article, we are going to see how to run the SharePoint Designer workflow /Nintex workflow through PowerShell script for bulk list items.
Through this PowerShell script we can run the workflow to multiple list items (if the workflow associated both item created and item updated events).
PowerShell Script:
if ( (Get-PSSnapin -Name Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue) -eq $null )
{
Add-PsSnapin Microsoft.SharePoint.PowerShell
}
#Provide Site URL and List Name
$siteUrl = 'Provide Site URL'
$listurl= 'Provide List URL'
$site = new-object Microsoft.SharePoint.SPSite($siteUrl)
$web = $site.OpenWeb();
$manager = $web.Site.WorkFlowManager
# Name of the list
write-host $listurl
$list = $web.getList($listurl)
$wfrunoption=[microsoft.sharepoint.workflow.spworkflowrunoptions]::synchronous
# Name of the Workflow
$assoc = $list.WorkflowAssociations.GetAssociationByName("Provide Workflow Name","en-US")
write-Host $assoc.Name
$data = $assoc.AssociationData
$items = $list.Items
foreach($item in $items)
{
if($itemNo -Ne $itemCount)
{
$wf = $manager.StartWorkFlow($list.GetItemById($item.ID),$assoc,$data,$true)
}
}
$manager.Dispose()
Write-Host "Workflow Completed Successfully"
$web.Dispose()
