How to Test Magento Webhooks

Magento (Adobe Commerce) async events and webhooks notify external services about order, customer, and product changes.

Magento Official Webhook Docs

1. Magento Webhook Events

Magento can send the following webhook events to your endpoint:

observer.sales_order_save_after
observer.customer_save_after
observer.catalog_product_save_after
observer.sales_order_shipment_save_after
observer.sales_order_creditmemo_save_after
plugin.after.place_order

2. Set Up a Test Endpoint with HookRay

Follow these steps to start receiving Magento webhooks for testing:

  1. Go to HookRay and click "Start Testing — Free" to get your unique webhook URL.
  2. Copy the URL (e.g., https://h.hookray.com/abc123).
  3. In your Magento dashboard, navigate to the webhook settings and paste the HookRay URL as your endpoint.
  4. Select the events you want to receive (see list above).
  5. Trigger a test event — HookRay will show the incoming webhook in real-time.

3. Sample Magento Webhook Payload

Here's an example of what a Magento webhook payload looks like:

payload.json
{
  "event": "observer.sales_order_save_after",
  "data": {
    "order": {
      "entity_id": "000000042",
      "increment_id": "100000042",
      "status": "processing",
      "grand_total": "259.99",
      "customer_email": "buyer@example.com"
    }
  }
}

4. Frequently Asked Questions

How do I test Magento webhooks without deploying?

Use HookRay to get an instant public webhook URL. Paste it into your Magento dashboard's webhook configuration, trigger an event, and watch the payload arrive in real time. No code, no ngrok, no deployment required. The free tier captures 100 requests per month and works on all Magento event types.

Why aren't my Magento webhooks arriving?

The four most common causes: (1) the endpoint URL isn't publicly accessible — Magento can't reach localhost; (2) the wrong events are subscribed in your Magento dashboard; (3) signature verification is rejecting the request before your handler runs; (4) Magento can't reach your server because of a firewall, expired SSL certificate, or wrong DNS. Use HookRay's URL to isolate which of these four is failing — if HookRay receives the webhook, the problem is in your handler. If HookRay doesn't, the problem is in Magento configuration.

Why am I getting 400 or 500 errors from my Magento webhook?

Magento reports the response status your endpoint returned. HookRay accepts any payload and returns 200 OK by default, so if you see 400/500 in your Magento dashboard while pointing at HookRay, the issue is in Magento's configuration (wrong event, malformed signing secret, etc.). If you point at your own endpoint and get 400/500, the issue is in your handler — capture the request with HookRay, replay it locally, and debug from the captured payload.

How do I verify Magento webhook signatures?

Magento signs each webhook request with a shared secret. Capture the raw headers and body using HookRay, then verify the signature in your application using Magento's SDK or a standard HMAC library. Once verification works against HookRay-captured data, you can safely deploy. Magento's docs (linked above) cover the exact signing algorithm.

Can I replay a captured Magento webhook?

Yes — HookRay's replay feature re-sends any captured webhook to a different endpoint with one click. This is the fastest way to fix a buggy handler: capture the payload once, fix your code, and replay until it works. No need to re-trigger the event in Magento.

5. Next Steps

  • Use HookRay's webhook replay feature to re-send captured webhooks while building your handler
  • Enable smart parsing (Pro plan) to see Magento-specific fields highlighted automatically
