Webhook Payload Generator
NewGenerate realistic sample JSON payloads for GitHub, Stripe, Slack, and generic webhooks to test your receiver endpoint without waiting for a real event.
These are realistic sample shapes for local testing — always verify against each provider's current official webhook documentation before relying on exact field names in production.
Frequently Asked Questions
Are these real payloads captured from GitHub/Stripe/Slack, or invented?
They're hand-built sample shapes modeled closely on each provider's publicly documented webhook payload structure, using realistic-looking but randomly generated IDs — not literal payloads copied from a real account's traffic.
Can I rely on every field being exactly correct for production parsing?
Treat this as a solid starting point for local development and endpoint testing, not a substitute for each provider's official documentation — webhook payload shapes occasionally gain new fields or nested objects over time, so double-check field names against current docs before shipping production parsing logic.
Why does clicking "Regenerate IDs" change the output?
Each payload embeds random-looking IDs (commit SHAs, Stripe object IDs, Slack channel/user IDs) generated fresh every time you switch providers or click Regenerate, so you get a new synthetic but structurally valid ID each time rather than the exact same values repeatedly.
Can I use this output to test HMAC signature verification code?
You can use the generated JSON body as the raw payload to sign, but this tool does not generate the provider-specific signature header (like Stripe-Signature or X-Hub-Signature-256) itself — you would need to compute that separately using your own webhook signing secret and the relevant HMAC scheme.
Does this actually send an HTTP request to my webhook endpoint?
No — it only generates the JSON text for you to copy and send yourself (e.g. via curl, Postman, or your own test script). It does not make any network requests.
