Test Resend webhooks

Resend sends webhooks for email events such as sent, delivered, opened, clicked, bounced, and complained, plus domain and contact changes. Capture them on a free webhooks.cc endpoint to see exactly what Resend sends, or fire realistic, correctly signed sample payloads at your own handler without touching a production account.

How to test Resend webhooks

  1. 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. 2

    Point Resend at your URL

    Paste the endpoint URL into Resend: Dashboard → Webhooks, or via the Webhooks API.

  3. 3

    Inspect what arrives

    Each delivery appears live in the dashboard with method, headers, body, query parameters, and source IP.

  4. 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.
