BillingWebhookKit

SaaS billing webhook test plan

Before launch, small SaaS teams need proof that checkout events change access correctly and safely.

Open the free generator

Cover the lifecycle

Test purchase, renewal, cancellation, refund, license creation, and failed payment events before switching checkout links live.

Verify access changes

Assert user entitlements, account status, billing records, and notification jobs after each fixture replay.

Keep a release gate

Make webhook tests part of the release checklist so billing regressions cannot ship quietly.

FAQ

How many fixtures are enough?

Start with one success and one failure fixture per critical billing state, then expand as support issues reveal gaps.

Can this run without live provider calls?

Yes. Fixture tests should run without network access; live checkout tests are a separate pre-launch check.
