A payment decline is not a reason to ask a customer to send a card screenshot. The return code and its text should come from the gateway log, with transaction ID, time, amount, currency, and operation type. The same numbers are not necessarily identical across providers, processing routes, and transaction types, so do not make decisions from a copied web code dictionary.
Map every response to a safe business action: request another payment method, retry at a defined time, send to staff review, or stop pending clarification. A technical response must never leak full card number, CVV, or authentication data into CRM, WhatsApp, or email.
Also distinguish a decline from uncertainty. If a request timed out, the charge may have been approved at the gateway even though the website received no response. Check by unique transaction identifier before charging again. In that case, a status lookup is safer than a try again button.
