It took me a while to work out the syntax to trigger a zap from a Windows DOS batch file, so I thought I would share it.
First, you will need to be sure that you have Windows PowerShell installed. This is open-source software supported by Microsoft. You will find more details and can download the software from the Microsoft Website here.
To trigger a zap from a DOS batch, use the following command:
powershell -NoProfile "irm ENTER-THE-FULL-ZAP-WEBHOOK-HERE | Out-Null"
Thas it. Run the batch file, and your zap will be triggered.
