Webhook Payload Generator

The Webhook Payload Generator produces realistic event payloads in the shapes used by popular services, so you can test webhook handlers, parsers, and integration logic without wiring up real accounts or waiting for live events.

How it works

Each service has its own builder that follows the documented payload structure:

• Stripe wraps a data.object inside the standard event envelope with id, type, created, and livemode: false.
• GitHub produces push, pull_request, issues, or star events with a repository, sender, and a 40-character commit SHA.
• Shopify emits order, product, customer, or checkout objects with line_items, total_price, and a customer.

IDs use each service’s prefixes and formats (for example evt_, cus_ for Stripe, a hex SHA for GitHub), and amounts, timestamps, and identifiers are randomised on every generation.

Tips and notes

• Use the generated JSON as a request body in curl or your test runner to exercise the parsing path of a handler.
• These payloads will not pass signature verification — that is intentional, because verification depends on a secret you control, not on the payload alone.
• Switch services to confirm your router branches correctly on the event type or topic header.
• Everything is local with no API key, so generate freely while iterating.
