Beast Insights
Claude connectorCommunityExplain card decline codes, chargeback reason codes and 3-D Secure results, and define payments terms, with a source link on every answer.
Beast Insights is a payments reference for merchants, payments operations teams, support agents and developers. Ask about a card decline, a chargeback or a 3-D Secure result and get a plain-English explanation, the likely cause, what to do next, and links to the source.
What it covers:
- Card decline codes: ISO 8583 response codes such as 05 "do not honor" and 51 "insufficient funds", and processor-specific codes from Stripe, Adyen, Braintree, NMI, Authorize.net, Checkout.com, Worldpay, PayPal and Square, with whether and when to retry.
- Chargeback reason codes: Visa, Mastercard, Amex and Discover reason codes such as 10.4 and 4853, what the cardholder is claiming, the response window and the evidence that usually wins.
- 3-D Secure results: transStatus and ECI values, what they mean for authentication and who carries liability.
- Payments terms: clear definitions of terms such as BIN, MID, acquirer, interchange, representment and soft vs hard declines.
What it does not do: it needs no sign-in, holds no customer data, never asks for card numbers, doesn't move money and doesn't recommend processors. Answers are reference information and cite their sources.
