Automate SSL Certificate Monitoring with Google Sheets and Email Alerts
This n8n workflow automatically checks SSL certificates for websites listed in a Google Sheet and sends email alerts if any are expiring within 14 days. This helps prevent downtime and security issues caused by expired certificates.
The workflow is triggered weekly and retrieves website URLs from a Google Sheet. It uses the ssl-checker.io API to fetch SSL certificate details, updates the spreadsheet with the latest SSL information, and evaluates certificates for upcoming expiration. If certificates are expiring soon, it sends email notifications to alert relevant parties.
New buyers can create an account from the cart to unlock a controlled $10 first-purchase credit on eligible orders of $25+.
