How to Test Adyen Webhooks

Adyen webhooks (notifications) inform your integration about payment authorizations, captures, refunds, and chargebacks across all payment methods.

Adyen Official Webhook Docs

1. Adyen Webhook Events

Adyen can send the following webhook events to your endpoint:

AUTHORISATION
CAPTURE
CANCELLATION
REFUND
CHARGEBACK
REPORT_AVAILABLE
PAYOUT_THIRDPARTY

2. Set Up a Test Endpoint with HookRay

Follow these steps to start receiving Adyen 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 Adyen 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 Adyen Webhook Payload

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

payload.json
{
  "live": "false",
  "notificationItems": [
    {
      "NotificationRequestItem": {
        "amount": {
          "currency": "EUR",
          "value": 1500
        },
        "eventCode": "AUTHORISATION",
        "merchantAccountCode": "TestMerchant",
        "merchantReference": "order_123",
        "pspReference": "8835511210681442",
        "success": "true"
      }
    }
  ]
}

4. Common Issues & Troubleshooting

Webhook not arriving?

Check that your endpoint URL is correct and publicly accessible. Adyen cannot reach localhost URLs — use HookRay's cloud URL instead.

Getting 400 or 500 errors?

HookRay accepts any payload and returns 200 OK by default, so the issue is likely on Adyen's side. Check your webhook configuration and event selection.

Need to verify webhook signatures?

Adyen signs webhook requests for security. Use HookRay to capture the raw headers and body, then implement signature verification in your application code.

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 Adyen-specific fields highlighted automatically
  • Check the Adyen webhook documentation for the complete event reference
