# Cron Job Management (lam.cron)

lam.cron is a powerful scheduling system that allows you to create, manage, and execute scheduled tasks (cron jobs) within your workflows. Users create cron steps by defining step programs that return `lam.cron` objects containing scheduling information, with support for creating, updating, deleting, and listing scheduled tasks.

## Key Concepts

A Cron job is created by defining step programs that return `lam.cron` object. Each cron operation consists of:

* **Operation Types**: Create, update, or delete
* **Cron Schedules**: Standard cron syntax for defining when tasks run
* **URL**: Destination of the POST request and body
* **Body**: JSON body that will be sent as part of the cron job

## Creating a cron job

```javascript
(data) => {
    return {
        "lam.cron": {
            "operation": "create",
            "name": "Daily Report",
            "schedule": "0 0 9 * * *",
            "url": "https://api.laminar.run/workflow/execute/external/308?api_key=your-key&configuration_id=58",
            "body": {
                "report_type": "daily"
            }
        }
    };
}
```

## Updating a cron job

```javascript
(data) => {
    return {
        "lam.cron": {
            "operation": "update",
            "name": "Daily Report",
            "schedule": "0 0 10 * * *", // Change from 9 AM to 10 AM
            "url": "https://api.laminar.run/workflow/execute/external/308?api_key=your-key&configuration_id=58",
            "body": {
                "report_type": "daily"
            }
        }
    };
}
```

## Deleting a cron job

```javascript
(data) => {
  // Your code here
  return   {
    "lam.cron": {
      "operation": "delete",
      "jobId":"229988fd-0308-472a-8385-380f2b97f461"
    }
  };
}
```
