Webhook Server documentation

Webhook Server is a Windows service that runs a script (PowerShell, cmd, or any executable) when an HTTP request hits a URL you choose. It's designed for sysadmins who want to wire a tool like Zerto pre/post scripts, GitHub Actions, a monitoring system, or a backup tool into a Windows-side automation step — without writing a custom listener every time.

The Zerto ZVMA recipe ships with zerto-zvma-send.ps1 (sender, runs inside the ZVMA scripts-service container) plus zerto-receiver-notify.ps1 and zerto-receiver-vm-healthcheck.ps1 (receivers, run on the Webhook Server host).
