Test Zendesk webhooks
Zendesk sends webhooks for ticket activity through triggers and automations, and for user, organization, and help center events. Capture them on a free webhooks.cc endpoint to see exactly what Zendesk sends, then replay deliveries or forward them to your local handler.

How to test Zendesk 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 Zendesk at your URL
Paste the endpoint URL into Zendesk: Admin Center → Apps and integrations → 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.
Zendesk webhook authentication
| Auth header | x-zendesk-webhook-signature |
|---|---|
| Algorithm | HMAC-SHA256 |
| Verification in webhooks.cc | Capture deliveries to inspect raw signature material |
The signature is base64(HMAC-SHA256(timestamp + body)), with the timestamp from x-zendesk-webhook-signature-timestamp.
