A launch checklist for Stripe Checkout Session 403 errors, restricted API keys, hosted Payment Link fallbacks, success URLs, and paid delivery.

Browser-only launch preflight
Selections only. No checkout URLs, session IDs, logs, or secrets are submitted.
Do not paste API keys, webhook secrets, bearer tokens, cookies, session IDs, customer PII, card details, raw logs, or private buyer messages.
Launch checklist
Product page states the exact file, template, report, access, or tool the buyer receives.
Price, one-time purchase status, refund/support boundary, and delivery timing are visible before checkout.
Stripe or another hosted checkout handles card details. This page does not collect raw card data.
Success URL includes the checkout session placeholder and lands on a server-verified delivery page.
Download or access route rejects missing, fake, unpaid, expired, wrong-amount, and wrong-product sessions.
Support copy asks for approximate purchase time only, not secrets, card data, customer PII, raw logs, or private files.
Sales, generator, waitlist/forms, public access, and notifications can be paused independently.
A fake checkout session was tested and denied before launch.
The operator can turn sales off without redeploying.

Plain boundaries
This is educational product-operations material, not legal, financial, banking, tax, compliance, or payments advice.
Do not paste API keys, webhook secrets, bearer tokens, cookies, session IDs, customer PII, card details, raw logs, or private buyer messages.
Use placeholders such as PRODUCT, PRICE, SUCCESS_URL, SESSION_ID, DOWNLOAD_ROUTE, and SUPPORT_EMAIL in the browser-only generator.
Hosted checkout should handle card details. The product page should collect the minimum data needed for self-serve delivery.
