Generate API contract tests from real webhook traffic.
Third-party APIs change without warning. Your Stripe or Shopify integration breaks because they added a field or changed a type. You only find out when customers complain. Writing and maintaining contract tests manually is tedious.
Backend developers integrating with webhooks who want to catch breaking changes before they cause production incidents.
Capture real webhook payloads, automatically generate contract tests, and get alerted before breaking changes hit production. We diff every payload against the expected schema and warn you when something changes.
A Stripe schema change shows up in your CI before it breaks your code. You update your handler with confidence, knowing the test suite covers real payload variations.
