Webhook Testing

Use webhook testing before production launch to confirm your endpoint accepts HTTPS requests, verifies signatures, and returns 2xx quickly.

Test payload

If you do not provide a custom payload, SimZ sends a simple test event.

  "event": "webhook.test",

}

What to check

• Endpoint URL starts with https://.
• Server reads the raw request body for signature verification.
• Response status is 2xx.
• Heavy downstream work runs asynchronously.
• Logs do not expose secrets.
