Monitor SSL certificates across websites listed in Google Sheets and receive timely email alerts before expiry.
This AI agent reads a Google Sheet of websites, queries their SSL certificates via ssl-checker.io, logs the results back to the sheet, and sends email alerts for certificates nearing expiry.
Executes the complete monitoring and alert workflow.
Fetches website entries from the Google Sheet.
Checks SSL certificate details using ssl-checker.io API.
Evaluates expiry dates and identifies certificates expiring within 14 days.
Updates the spreadsheet with Issued On and Expired On data.
Filters results to expiring soon and marks status in the sheet.
Sends email alerts to notify stakeholders.
This section explains practical workflow improvements before and after adopting the AI agent. It highlights concrete pain points and measurable outcomes to help you judge value.
A simple three-step system you can configure in minutes.
Runs on a weekly schedule and reads all website rows from the Google Sheet.
Calls ssl-checker.io for each URL, capturing Issued On, Expires On, and status, then writes results back to the sheet.
Filters for certificates expiring within 14 days and sends email alerts to stakeholders.
A realistic scenario showing setup, timing, and outcomes.
Scenario: Monday 7:00 AM, 12 websites listed in Google Sheets. The AI agent reads the sheet, checks SSL expiry with ssl-checker.io, updates the sheet with Issued On/Expired On, then sends 3 email alerts for domains expiring in 10, 8, and 5 days. Outcome: you have a centralized, up-to-date sheet and proactive email alerts enabling renewals before downtime.
Target roles that manage SSL, security, and website uptime.
Owns certificate renewals and wants automated visibility.
Need a centralized renewal workflow across multiple domains.
Monitors certificate trust and expiry risk as part of risk management.
Provides clients with proactive SSL monitoring and alerts.
Keeps sites secure with timely renewals.
Maintains auditable expiry records for audits.
Uses familiar tools to implement the monitoring pipeline.
Reads and writes SSL data to a spreadsheet, keeping Issued On/Expired On columns up to date.
Provides certificate details (issued/expiry) for each domain used to trigger alerts.
Delivers expiry alerts to recipients and logs the notification.
Six practical scenarios that demonstrate concrete outcomes.
Common questions and practical answers.
A single source of truth with columns for Link, Issued On, Expired On, and Status. The AI agent reads URLs and writes back Issued On/Expired On data after checking SSL. You should ensure the Link column contains valid URLs, and the sheet is accessible to the automation runner.
The workflow is scheduled weekly by default, but you can configure the cadence. It scans every listed website, updates the sheet, and triggers alerts for expiring certificates. If a check fails, it logs the failure and retries on the next run.
Yes. You can specify email addresses to receive alerts in the configuration. Alerts include domain, expiry date, days left, and a direct link to the monitored URL. The agent also logs each notification for audit.
Expired certificates are flagged in the sheet and can trigger remediation tasks. Alerts push to the configured recipients, and you can extend the workflow to escalate to ticketing or paging. Renewal actions should be coordinated with your certificate authority.
If the API call fails, the agent records the failure and retries on the next run. It can be configured with exponential backoff and alerting for API outages. A fallback can be added to skip the domain and continue with others.
The agent only reads and writes data to the configured Google Sheet and uses a secure SSL API. Credentials should be stored in a secure vault and access restricted. You can enable audit logs to demonstrate data handling and controls.
No dedicated hosting is required if you use the provided n8n template or cloud runner. You just provide Google Sheets access and SMTP credentials. The setup is quick, and you can scale by adding more URLs over time.
