Write a plain language explainer of one payment decline code

Pick the decline or error code that generates the most support tickets, such as a specific card network response code. Write a short explainer covering what it means, why it happens, and what the merchant should do about it, and link that page directly from the in-app error message.

Why it works: Merchants searching a cryptic decline code by name will land on your explainer, associating your brand with the answer instead of a generic forum thread.
