Webhook tester guide: test endpoint, payload, and response
Use a webhook tester to validate endpoint behavior before production: status code, latency, headers, and payload handling. This guide gives a practical test flow for Stripe, GitHub, and custom webhooks.
Common causes
- Endpoint returns 4xx/5xx for valid webhook payloads.
- Server accepts JSON but fails on provider-specific headers.
- Retries happen because response is slow or malformed.
How to fix
- Create a dedicated test endpoint and log raw request body.
- Send realistic payloads and provider headers with a webhook tester.
- Verify response status, latency, and idempotency behavior for retries.
