Cert credential expiry sentinel is an n8n automation template that runs on a schedule to check certificate or credential expiration dates and sends alert emails via Gmail. Reach for it when you need to stop missing the moment an SSL certificate or API key is about to expire, when the team is tired of manually tracking expiry dates across accounts and certs, or when you want an automatic email warning before a service goes down due to lapsed credentials. Trigger: schedule. Integrations: Gmail. The template is deployed in n8n — self-hosted or cloud — by importing a JSON workflow, no custom code required. The direction is proactive expiry monitoring and notification, not certificate issuance or renewal — for PKI management you'll need dedicated tooling. A good fit for DevOps teams, IT support, and sysadmins who need credential expiry under control; not suitable if you need alerts in Slack or other messengers — Gmail only.
