Checks the SSL certificate validity for a given domain and sends an alert if it has expired.

About This Workflow

This workflow automates the process of checking the SSL certificate status for a specified domain. It retrieves SSL certificate information and then evaluates if the certificate has expired. If an expiry is detected, it triggers an alert via Telegram.

Key Features

Automatically retrieves SSL certificate details for a specified domain.
Evaluates the certificate's validity.
Sends instant notifications to a designated Telegram chat upon certificate expiry.

How To Use

On clicking 'execute': This node initiates the workflow.
Create Domain Item: This node defines the domain for which the SSL certificate will be checked. Currently set to 'n8n.io'. You can modify the functionCode to check other domains.
Get SSL Certificate: This node utilizes an external 'uproc' tool to fetch the SSL certificate details for the domain specified in the previous node. It requires a 'miquel-uproc' credential.
Certificate has expired?: This node acts as a condition. It checks the 'valid' field from the 'Get SSL Certificate' node's output. If 'valid' is false (meaning the certificate has expired), the workflow proceeds to the next step.
Send Expired Alarm: If the certificate is found to be expired, this node sends a message to a specific Telegram chat ID using the 'test killia bot' credential. The message includes the domain name.
