Usage

Cronlytic Trigger Node

The Cronlytic Trigger node creates scheduled jobs on Cronlytic that trigger your n8n workflows via webhooks.

Configuration Options:

• Job Name: Unique identifier for the cron job (alphanumeric, hyphens, underscores only)
• Cron Expression: 5-field cron expression (minute hour day month day-of-week)
• Webhook Body: Optional JSON payload to send with the webhook
• Additional Headers: Custom headers for webhook requests

Example Cron Expressions:

• */5 * * * * - Every 5 minutes
• 0 9 * * 1-5 - 9 AM on weekdays
• 0 0 1 * * - First day of every month
• 30 14 * * 0 - 2:30 PM every Sunday

Example Workflow

1. Add a Cronlytic Trigger node to your workflow
2. Configure credentials
3. Set job name: daily-report-generator
4. Set cron expression: 0 9 * * * (daily at 9 AM)
5. Add webhook body: {"source": "cronlytic", "type": "daily_report"}
6. Connect to your processing nodes
7. Activate the workflow

When activated, this creates a job on Cronlytic that will trigger your workflow daily at 9 AM.

Advanced Features

Custom Webhook Payloads

{
  "trigger_time": "{{timestamp}}",

}

Error Handling

The node includes built-in error handling:

• API connection retries with exponential backoff
• Automatic lambda warming for reliable execution
• Detailed error messages for troubleshooting

Job Management

Jobs are automatically managed by n8n:

• Created when workflow is activated
• Updated when node configuration changes
• Deleted when workflow is deactivated or node is removed
