Each job gets a unique webhook URL. Copy it from the job detail page:

https://webhook.cronlabs.dev/catch/abc123xyz

This URL is where your cron job will send requests.

Add a Ping to Your Script

Modify your script to send a request to CronLabs when it runs:

# Bash - Add to end of your script
curl -X POST https://webhook.cronlabs.dev/catch/abc123xyz \
  -H "Content-Type: application/json" \
  -d '{"status": "completed", "records": 847}'
# Python
import requests

requests.post(
    "https://webhook.cronlabs.dev/catch/abc123xyz",
    json={"status": "completed", "records": 847}
)
# Node.js
fetch("https://webhook.cronlabs.dev/catch/abc123xyz", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ status: "completed", records: 847 })
});
