How it works
Up and running in minutes
1
Get a unique URL
Each heartbeat monitor gets a dedicated HTTPS endpoint URL.
2
Ping from your job
Add one line at the end of your cron job: curl -X POST https://api.howlops.com/api/v1/hb/YOUR_SLUG
3
Set expected interval
Tell us how often your job should run — every minute, hourly, daily. With optional grace period.
4
Alert on silence
If the ping doesn't arrive within the grace period, we trigger an alert immediately.
