# Weekly SSL certificate expiry monitor for client websites

**Use case:** 

Check SSL/TLS certificates on a list of domains in bulk and flag expired, self-signed or soon-to-expire certificates (30-day warning). Schedule it weekly for agency client sites or a merchant portfolio, and send problems to Slack, email or your ticketing tool via Zapier, Make or n8n. Demo uses example.com and public badssl.com test domains.

## Input

```json
{
  "domains": [
    "example.com",
    "example.org",
    "expired.badssl.com",
    "self-signed.badssl.com"
  ],
  "warnDays": 30,
  "onlyProblems": false
}
```

## Output

```json
{
  "domain": {
    "label": "Domain",
    "format": "string"
  },
  "status": {
    "label": "OK, EXPIRING_SOON, EXPIRED, INVALID, UNREACHABLE, INVALID_INPUT",
    "format": "string"
  },
  "daysLeft": {
    "label": "Days until expiry",
    "format": "integer"
  },
  "notAfter": {
    "label": "Expires",
    "format": "string"
  },
  "issuer": {
    "label": "Issuer",
    "format": "string"
  },
  "tlsVersion": {
    "label": "TLS version",
    "format": "string"
  },
  "verifyError": {
    "label": "Verification error",
    "format": "string"
  },
  "sans": {
    "label": "Subject alternative names",
    "format": "array"
  },
  "ok": {
    "label": "Check completed",
    "format": "boolean"
  }
}

## About this Actor

This example demonstrates how to use [SSL Certificate Checker & Expiry Monitor](https://apify.com/sterlingverify/ssl-expiry-monitor.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/sterlingverify/ssl-expiry-monitor.md) to learn more, explore other use cases, and run it yourself.


## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/sterlingverify/ssl-expiry-monitor.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
