YOUR CHECKOUT PAGE IS LYING. THIS PROMPT PROVES IT

Summary from the TLDR Marketing newsletter

Checkout success screens can hide backend failures where payments go through, but access is not granted due to webhook or database write issues. A data integrity audit treats the payment processor as the source of truth, maps the required database update, and verifies it with direct queries before launch. This guide includes a reusable prompt and explains how to run it to structure and execute this verification process.
