BillingWebhookKit

SaaS webhook release checklist

Before a billing release, teams need a short list of checks that prevent duplicate entitlements, missed cancellations, and broken checkout fulfillment.

Open the free generator

Run success and failure fixtures

Cover paid order success, failed signature, duplicate replay, unsupported event, cancellation, renewal, and license creation.

Inspect access transitions

Check that users move between trial, paid, cancelled, expired, refunded, and license-enabled states as expected.

Verify production configuration last

Only after local and CI fixtures pass should you test the live provider webhook URL, checkout link, and webhook secret wiring.

FAQ

What is the highest-risk billing release bug?

Processing the same provider event twice is one of the most common and expensive mistakes because it can duplicate access, emails, or records.

Can this checklist run without paid services?

Most checks can run with local fixtures and CI. The final provider checkout verification is separate and should use the payment provider's allowed test or live flow.
