Launch evidence
Billing webhook launch evidence pack
A payment page is not launch evidence. Before exposing a public buy link, collect proof that production checkout is ready, checkout loads, paid webhooks arrive, signature gates hold, delivery runs once, refund rollback is safe, and the support path is clear.
Confirm live key setup, CN¥69 price, PayPal, signed webhooks, and private delivery gates.
Generate a secret-free go-live report for production checkout configuration, published variant, paid webhook delivery, duplicate replay, refund rollback, support policy, and release evidence.
Prove the checkout page, price, and paid event path.
Generate a release-ready report for product price, checkout URL, paid webhook delivery, signature gate, duplicate replay, fulfillment, and rollback notes.
List the webhook events your launch actually depends on.
Map order, subscription, license, paid-state, signature, idempotency, and duplicate replay coverage before production traffic starts.
Show what happens after the buyer pays.
Create evidence for signed paid events, private ZIP or license delivery, live variant checks, idempotency, checksum records, and support policy links.
Prove access changes do not repeat on refund retries.
Generate secret-free evidence for signed refund webhooks, entitlement revocation, duplicate replay safety, support notes, and release review.
Prepare delivery, resend, and support messages.
Draft buyer-facing emails with private ZIP safety, checksum evidence, refund boundaries, support policy links, and no public secret leakage.
