American Express P04 chargeback: Charge Processed as Credit explained
Checked
American Express reason code P04, Charge Processed as a Credit, means a sale was submitted as a credit by mistake. Like P03, the chargeback is for twice the amount. Answer with proof the transaction was processed correctly. Separate refund and sale flows, and checking transaction types before submitting, prevent it.

For developers
On Stripe the dispute object arrives with reason "general" and the card network's own code in payment_method_details.card.network_reason_code; listen for charge.dispute.created and read evidence_details.due_by for the deadline.
American Express uses one letter plus two digits for US and Canada merchants; elsewhere it uses four-digit ISO codes, and each letter code sits under one.
