BillingWebhookKit

Stripe webhook fixture generator

Stripe integrations need repeatable checkout and invoice events in CI, not only manual dashboard retries.

Open the free generator

Cover checkout completion

Keep a checkout.session.completed fixture for account creation, entitlement grants, and onboarding redirects.

Cover invoice payment

Use invoice.paid or invoice.payment_failed fixtures to test subscription renewal and dunning behavior.

Keep provider boundaries clean

Normalize Stripe, Lemon Squeezy, Paddle, and Polar events into your own internal billing events.

FAQ

Is this a Stripe API wrapper?

No. It is a fixture and test workflow for local development.

Why include multiple providers?

Provider-specific fixtures help small SaaS teams migrate or support multiple billing providers with less brittle code.
