SSL Certificate Monitoring

AlertifyPro automatically monitors SSL certificates for any service configured with check_type: "SSL". Certificates are checked for validity and proximity to expiry.

How it works

Add a service with check_type: "SSL" and provide the domain as the endpoint:

POST /api/v1/services
Authorization: Bearer <token>
Content-Type: application/json

{
  "name": "API TLS Certificate",
  "endpoint": "api.yourapp.com",
  "check_type": "SSL",
  "check_interval_seconds": 3600
}

tip

SSL checks run less frequently than HTTP checks — once per hour (3600 seconds) is typically sufficient.

What's checked

The SSL probe (checker/tls.go) connects to the domain on port 443 and verifies:

• TLS handshake succeeds
• Certificate is not expired
• Certificate expiry is not within the warning threshold (configurable via expiryWarningDays)

Status values:

Status	When
GREEN	Certificate valid and not nearing expiry
YELLOW	Certificate nearing expiry (within warning threshold)
RED	Certificate expired or TLS handshake failed

Viewing SSL certificates

GET /api/v1/ssl-certificates
Authorization: Bearer <token>

Returns a list of all SSL certificates AlertifyPro has tracked across your organization's SSL-type services:

[
  {
    "service_id": "uuid",
    "domain": "api.yourapp.com",
    "issuer": "Let's Encrypt",
    "valid_from": "2026-01-01T00:00:00Z",
    "valid_to": "2026-04-01T00:00:00Z",
    "days_until_expiry": 29,
    "status": "YELLOW"
  }
]

Alert when certificates expire

Create an alert rule for SSL services so you're notified before expiry:

POST /api/v1/alert-rules
{
  "service_id": "<ssl-service-uuid>",
  "name": "SSL Near Expiry",
  "severity": "warning"
}
