We have Powershell that creates a ticket in ServiceNow after the Request is submitted in AP. I added some logging to write both the AP order id and the ServiceNow Request Number. I have created a Powershell Web Service to read the log file and populate the customer email with the ServiceNow Request Number. However I am unable to trigger the PowerShell Web Service as part of the Email Task. Is trigging a PS Web Service outside the customer interface possible?
