Guard against out-of-band Cloudflare DNS changes

When a Cloudflare DNS change webhook fires, checks the changed record against the Coda registry and immediately alerts Discord if the change was not authorized in the source…

What it does

This workflow turns Cloudflare DNS edits into real-time events and validates each one against the Coda registry. The moment a record is created, updated, or deleted, the incoming payload is compared to the registry: if the new state matches an authorized row in Coda the event is logged quietly, but if the change has no backing in the registry it is flagged as unauthorized and an alert with the record details and actor is sent to Discord. This shrinks the window between an unsanctioned change and someone noticing from a day to seconds.

When to use it

Use it on zones where every DNS change is supposed to flow through Coda and you want a tripwire for direct dashboard or API edits, including those made by compromised credentials or well-meaning teammates bypassing the process.

How it works

  1. 1A Cloudflare change webhook delivers the event payload.
  2. 2Parse the affected record's name, type, and new value.
  3. 3Look up the matching authorized row in the Coda registry.
  4. 4Decide: authorized (matches registry) or unauthorized (no match).
  5. 5For unauthorized changes, post an alert to Discord with the record, change type, and actor.
