What it does

This is an event-driven responder rather than a scheduled scan. It receives Vercel webhook events for domain and deployment changes, isolates the ones that signal a domain is unverified or misconfigured, and pages on-call in real time so a broken domain is caught within seconds of going bad rather than at the next daily sweep.

When to use it

Use it for high-traffic or revenue-critical domains where the delay of a scheduled check is unacceptable. It complements the daily watchdog: the schedule catches slow drift, this catches sudden breakage the moment Vercel observes it.

How it works

The webhook trigger receives Vercel events at an HTTP endpoint with signature verification. A logic step filters to `domain.created`, `domain.verification.failed`, and deployment events carrying a misconfigured-domain flag, dropping everything else. For a qualifying event, an action enriches it by fetching the domain's current required records from Vercel. An action then triggers a high-urgency PagerDuty incident including the offending domain and the records that must be set. A final output mirrors the alert to a Microsoft Teams channel for broad team visibility.
