■ Webhook Testing
Test webhooks for real, without waiting for the event to happen.
Generate a URL instantly, watch headers and body arrive live, and simulate the real sequence of events a provider (Stripe, GitHub, PayPal, Shopify) fires — no need for a real event to test.
Testing webhooks the manual way
- Waiting for a real payment to happen just to see what payload a provider sends
- No visibility into what actually arrived — headers, body, how many times
- The provider retries because your test endpoint doesn't respond 200 fast enough
- Testing only the success case, missing the real sequence (pending → processing → success/failure)
With httpdrop
- Instant, no-signup URL — the Webhook Tester shows every request arriving live
- Catch-all rule responds 200 automatically, no risk of a retry storm during development
- Response Sequences simulate a provider's real event sequence, one response per call
- Conditional templating in the full dashboard to react to different event types
- Replay any received request straight from history
How it works
1
Generate the URL
No login: open the Webhook Tester and get a unique URL instantly.
2
Point the provider at it
Paste the URL into Stripe, GitHub, PayPal, Shopify, or any service's webhook config.
3
Watch requests live
Headers, body and query show up on screen as they arrive, via WebSocket.
4
Graduate to a full rule
Create an account and build a Mock Rule with event sequencing and conditional logic.
5
Test edge cases
Simulate a declined payment, a PR closed without merge, a cancelled order — not just the happy path.
What httpdrop Webhook Testing is
- Payload and event-sequence simulation, with full inspection of every received request
- A fast environment to develop and test your own handler, without depending on the real provider
What it isn't
- Doesn't generate a valid HMAC signature (
stripe-signature,X-Hub-Signature-256) — signature verification needs to be tested separately, with the provider's own tools - Not a substitute for testing against the real provider before going live
Use cases
Payment integrations
Build your payment webhook handler without depending on real transactions to test every state.
CI/CD and review bots
Test automations that react to Pull Request events without opening and closing real PRs.
Debugging a broken integration
See exactly what a provider is sending when something doesn't match the docs.
FAQ
Do I need an account to test?
No — the Webhook Tester gives you a URL valid for 4 hours, no login. To keep the URL longer or add logic, create a free account.
Is it safe to point a real webhook (Stripe, GitHub) at this URL?
Yes — every request gets an automatic 200 OK, so there's no risk of a retry storm from the provider.
Can I test webhook signature verification?
Not directly — httpdrop simulates payload and sequence, not signature cryptography. See the webhook articles on /learn for how to test that step separately.
