This guide walks you through creating your first recurring cron using the CronAPI REST API.

​
Prerequisites

​
1. Get your API key

Log into the dashboard and navigate to the API Key page. Your API key is generated automatically on first visit. Copy it — you will only see the full key once.

​
2. Create a cron

Schedule a webhook that fires every 5 minutes: 
curl -X POST https://app.cronapi.dev/api/v1/crons \
  -H "Authorization: Bearer your_api_key_here" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Health check",
    "cron": "*/5 * * * *",
    "url": "https://example.com/health",
    "method": "GET"
  }'
You will receive a response like: 
{
  "id": "{your_cron_id}",
  "name": "Health check",
  "cron": "*/5 * * * *",
  "url": "https://example.com/health",
  "method": "GET",
  "headers": {},
  "body": {},
  "paused": false,
  "next_run_at": "2026-04-15T14:35:00.000Z",
  "created_at": "2026-04-15T14:31:00.000Z"
}

​
3. Test it immediately

Trigger the cron manually without waiting for the next scheduled run: 
curl -X POST https://app.cronapi.dev/api/v1/crons/{your_cron_id}/trigger \
  -H "Authorization: Bearer your_api_key_here"

{
  "status_code": 200,
  "success": true,
  "response_time_ms": 145,
  "fired_at": "2026-04-15T14:31:30.123Z"
}

​
4. Check execution history

View the last runs for your cron: 
curl https://app.cronapi.dev/api/v1/crons/{your_cron_id}/runs \
  -H "Authorization: Bearer your_api_key_here"
