Test Zoom webhooks
Zoom sends webhooks for meeting, webinar, recording, chat, phone, user, and account events. Capture them on a free webhooks.cc endpoint to see exactly what Zoom sends, then replay deliveries or forward them to your local handler.

How to test Zoom webhooks
- 1
Create a webhook endpoint
Sign in free with GitHub, Google, or email to create a persistent endpoint — or grab an instant guest URL at webhooks.cc without an account.
- 2
Point Zoom at your URL
Paste the endpoint URL into Zoom: Zoom App Marketplace → your app → Features → Event Subscriptions.
- 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.
Zoom webhook authentication
| Auth header | x-zm-signature |
|---|---|
| Algorithm | HMAC-SHA256 |
| Verification in webhooks.cc | Capture deliveries to inspect raw signature material |
The value is v0={hex}, computed over v0:{x-zm-request-timestamp}:{body} with the app's secret token. Zoom also sends an endpoint.url_validation challenge that your endpoint must answer.
