SSL Expiry Alert
This workflow implements automatic monitoring of SSL certificate validity for multiple websites. It regularly retrieves URLs to be checked from Google Sheets and uses the SSL-Checker.io API to check the certificate status in real-time. If a certificate is set to expire within 7 days, the system automatically sends an email reminder to enhance the automation and timeliness of certificate management, effectively preventing security risks and service interruptions caused by expired certificates, and ensuring the safe and stable operation of the websites.
Workflow Name
SSL Expiry Alert
Key Features and Highlights
This workflow automates the monitoring of SSL certificate validity across multiple websites by leveraging the SSL-Checker.io API for real-time certificate status checks. It periodically updates certificate details in Google Sheets and automatically sends email alerts when certificates are approaching expiration (within 7 days), significantly enhancing the automation and timeliness of SSL certificate management.
Core Problem Addressed
Expired SSL certificates can lead to website security vulnerabilities and service interruptions. Traditional manual monitoring methods are prone to errors and inefficiencies. This workflow resolves the issue of untimely certificate expiry notifications through automation, helping to prevent security incidents and business disruptions.
