1 — Log in and create a channel
Sign in at app.hookcheck.dev with your GitHub or Google account. From the dashboard, click "New Channel". Give it a name like stripe-test or github-pushes. HookCheck instantly generates a unique URL such as https://hck.io/ch/8f3a2b1c.
2 — Copy your endpoint URL
Click the copy icon next to your channel URL. Paste it into the webhook settings of the service you're debugging — for example, the Webhooks section of your Stripe dashboard, the Integrations → Webhooks page in GitHub, or the Notifications tab in your Shopify admin.
3 — Trigger a real event
Perform the action that fires the webhook: push a commit to your repo, create a test payment in Stripe, or send a manual request with curl:
curl -X POST https://hck.io/ch/8f3a2b1c -H "Content-Type: application/json" -d '{"event":"test_push","repo":"my-api","timestamp":"2025-01-15T09:42:00Z"}'
4 — View the captured request
Open your channel in the HookCheck dashboard. You'll see the full request: HTTP method, headers, raw body, and response status. Click any request to inspect individual headers, replay the payload, or share a read-only link with your team.
