How it works

Register with your email

Hit POST /register with your email. Get an API key back immediately. No dashboard, no OAuth, no waiting.

Create a scheduled job

POST a cron expression and a webhook URL. Any valid cron syntax works — every minute, hourly, daily, weekly, or custom.

Your webhook fires on schedule

CronHook sends a POST to your URL at the right time, every time. Check execution history via API to see status, response codes, and timing.

Built for production

Everything you need, nothing you don't. Simple API, serious reliability.

🔒

SSRF protection

Webhook URLs are validated against private IPs, loopback addresses, and cloud metadata endpoints before every execution.

📋

Execution history

Every run is logged — status, HTTP response code, duration, and error detail. Queryable via API.

🔑

API key rotation

Lost your key? Request a rotation token via email and swap to a new key without losing any jobs.

⚡

Custom headers & payload

Send any JSON payload and custom headers with each webhook call. Perfect for auth tokens and versioning.

🔄

Enable / disable jobs

Pause a job without deleting it. Resume any time. Update the schedule or URL via PATCH.

🌐

Any cron expression

Standard 5-field cron syntax. Every minute, every hour, specific days — full flexibility.
