Test Adyen webhooks
Adyen sends standard notification webhooks for authorisations, captures, refunds, and chargebacks. Capture them on a free webhooks.cc endpoint to see exactly what Adyen sends — or fire realistic, correctly signed sample payloads at your own handler without touching a production account.

How to test Adyen webhooks
- 1
Create a webhook endpoint
Sign in free with GitHub or Google to create a persistent endpoint — or grab an instant guest URL at webhooks.cc/go without an account.
- 2
Point Adyen at your URL
Paste the endpoint URL into Adyen: Adyen Customer Area → Developers → Webhooks → Create webhook.
- 3
Inspect what arrives
Each delivery appears live in the dashboard with method, headers, body, query parameters, and source IP.
- 4
Forward to localhost or assert in CI
Run whk tunnel <port> to forward webhooks to a local server, or use the TypeScript SDK to wait for and assert on deliveries in tests.
Adyen webhook signature
| Algorithm | HMAC-SHA256 |
|---|---|
| Verification in webhooks.cc | Supported — add your hmac key and every request is checked automatically |
Adyen does not use a conventional signature header — the HMAC is embedded in the notification body. Capture a real delivery to inspect exactly what is sent.
