Why SSL Certificate Monitoring Matters

Expired SSL certificates cause immediate website outages, browser warnings, and lost customer trust. Major companies lose millions when certificates expire unexpectedly. Automated monitoring prevents these costly incidents.

C&E Networks SSL Monitoring API

curl -X POST https://e4k2g0cyql.execute-api.us-east-1.amazonaws.com/prod/v1/ssl \
  -H "Content-Type: application/json" \
  -d '{"domain": "yoursite.com", "apiKey": "YOUR_API_KEY"}'

Python Implementation

import requests
from datetime import datetime

def check_ssl_certificate(domain, api_key):
    response = requests.post(
        'https://e4k2g0cyql.execute-api.us-east-1.amazonaws.com/prod/v1/ssl',
        json={'domain': domain, 'apiKey': api_key}
    )
    
    data = response.json()
    
    if data['valid']:
        days_left = data['daysUntilExpiry']
        if days_left < 30:
            print(f"⚠️  WARNING: {domain} SSL expires in {days_left} days!")
        elif days_left < 7:
            print(f"🚨 CRITICAL: {domain} SSL expires in {days_left} days!")
        else:
            print(f"✅ {domain} SSL valid for {days_left} more days")
    else:
        print(f"❌ {domain} SSL certificate is invalid!")
    
    return data

# Monitor multiple domains
domains = ['yoursite.com', 'api.yoursite.com', 'cdn.yoursite.com']
for domain in domains:
    check_ssl_certificate(domain, 'YOUR_API_KEY')

Automated Monitoring Setup

Daily Cron Job

# Check SSL certificates daily at 9 AM
0 9 * * * /usr/bin/python3 /path/to/ssl_monitor.py

Integration with Slack

import requests

def send_slack_alert(domain, days_left):
    webhook_url = "YOUR_SLACK_WEBHOOK"
    
    if days_left < 7:
        color = "danger"
        emoji = "🚨"
    elif days_left < 30:
        color = "warning" 
        emoji = "⚠️"
    else:
        return  # No alert needed
    
    message = {
        "attachments": [{
            "color": color,
            "text": f"{emoji} SSL certificate for {domain} expires in {days_left} days!"
        }]
    }
    
    requests.post(webhook_url, json=message)
