Paddle webhook test payloads

Paddle billing flows need deterministic webhook payloads for purchase, renewal, cancellation, and refund states.

Open the free generator

Model the lifecycle

Start with transaction completed, subscription updated, subscription canceled, and refund events.

Assert your mapping

Test that Paddle payload fields map into your app's customer, subscription, and entitlement records.

Run in CI

Store provider fixtures alongside handler tests so billing regressions fail before deployment.

FAQ

Do fixtures replace sandbox tests?

No. Fixtures make daily development fast; sandbox tests still verify provider behavior before release.

Can I use the same route for all providers?

You can share internal billing services, but keep provider signature verification separate.
