+# 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.

+3. [Recipe: Zerto failover post-script → DNS + service checks](recipes/zerto-pre-post-scripts.md) — the canonical reason this exists
