Automated SSL Certificate Monitoring & Renewal with Notion & Telegram

This workflow automates SSL certificate monitoring and renewal to prevent service interruptions. It pulls domain lists from a Notion database, queries the SSL-Checker API for each domain's certificate validity, and flags any expiring within 14 days. If issues are detected, it sends Telegram alerts, executes SSH commands to trigger Certbot renewal on remote servers, and re-verifies the certificates post-renewal with success notifications.

Key benefits include proactive security management, reduced manual oversight, and reliable uptime for web services. It handles repeated triggers intelligently by recording initiators, avoiding loops, and updating Notion with fresh validity data. Ideal for DevOps teams managing multiple domains.

Use cases: Hosting providers tracking client sites; IT teams with self-hosted apps; agencies maintaining client infrastructure. Integrates Notion for inventory, Telegram for instant alerts, SSL-Checker for checks, and SSH for actions—streamlining what would otherwise be manual cron jobs or scripts.

The logic branches via IF nodes: expiring certs trigger renewal paths; healthy ones update Notion directly. Post-renewal recursion ensures verification, closing the loop autonomously.
