Critical Cloudflare Cert Expiry to PagerDuty Incident
Watches Cloudflare certificates several times a day and, for any production-zone cert inside the critical window or already expired.
How it runs
The automated pipeline, trigger to output.

- ActionRead cert expiry for production-tagged zonesCloudflare
- LogicKeep only critical-window or expired certs
- LogicBuild stable dedup key per certificate
- OutputOpen or update routed PagerDuty incidentPagerDuty
What it does
This workflow treats an imminent cert lapse on a production zone as a pageable incident. It checks Cloudflare certificates on a frequent cadence, and when a production cert falls inside the critical window or has already expired it opens a PagerDuty incident with a dedup key so the same cert never pages twice. Lower-priority zones are intentionally excluded.
When to use it
Use it for the small set of domains where an expired certificate is a customer-facing outage. This is the last line of defense behind your task-based sweeps — if everything else was missed, the on-call gets paged before traffic breaks.
How it works
- 1A schedule fires several times a day for tight coverage.
- 2The workflow reads certificate expiry for the zones tagged production.
- 3A filter keeps only certs inside the critical window or already expired.
- 4It builds a stable dedup key per certificate to prevent duplicate pages across runs.
- 5It opens or updates a PagerDuty incident with the hostname, expiry, and severity, routing to the correct escalation policy.
