# Check SSL certificate expiry for a list of domains

**Use case:** 

Check the SSL/TLS certificate of each domain and get the issuer, valid-from and valid-to dates, days left until expiry, and whether the certificate is valid. Expired, self-signed or mismatched certificates are flagged with the error. Schedule it weekly to catch certificates before they expire.

## Input

```json
{
  "domains": [
    "github.com",
    "stackoverflow.com",
    "expired.badssl.com",
    "self-signed.badssl.com"
  ],
  "checkWhois": false,
  "checkDns": false,
  "checkSsl": true,
  "concurrency": 10
}
```

## Output

```json
{
  "domain": {
    "label": "Domain"
  },
  "sslIssuer": {
    "label": "Ssl issuer"
  },
  "sslSubject": {
    "label": "Ssl subject"
  },
  "sslValidFrom": {
    "label": "Ssl valid from"
  },
  "sslValidTo": {
    "label": "Ssl valid to"
  },
  "sslDaysLeft": {
    "label": "Ssl days left"
  },
  "sslValid": {
    "label": "Ssl valid"
  },
  "sslError": {
    "label": "Ssl error"
  }
}
```

## How it works

### 1. Sign up on Apify or log in

The Domain Expiry, DNS & SSL Certificate Checker (Bulk) Actor is ready to run with the inputs already set for "Check SSL certificate expiry for a list of domains". [Sign up or log in](https://console.apify.com/create-task-from-example/ABewTtuhqGbUGVodY) and you'll land in Apify Console with a copy of this exact task.

### 2. Start the "Check SSL certificate expiry for a list of domains" task

The Domain Expiry, DNS & SSL Certificate Checker (Bulk) Actor will start running based on the input automatically. You can also change all the input fields, like domains, registration data (rdap), and more, to match your specific use case.

### 3. Receive the "Check SSL certificate expiry for a list of domains" output

Monitor the progress in real time. You will be notified as soon as your dataset is complete and ready for review. Each result includes data such as domain, ssl issuer, ssl subject, and more.

### 4. Integrate into your workflow

The final output is delivered in JSON, CSV, or Excel format, ready to be plugged into your workflow. You can also [run the "Check SSL certificate expiry for a list of domains" task via API](https://apify.com/quillbit-tools/domain-expiry-dns-ssl-checker.md).

## About this Actor

This example demonstrates how to use [Domain Expiry, DNS & SSL Certificate Checker (Bulk)](https://apify.com/quillbit-tools/domain-expiry-dns-ssl-checker.md) with a specific input configuration.

## 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/quillbit-tools/domain-expiry-dns-ssl-checker.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`).
