Each page says why, and what to check before you concede.
Before you accept
- Already refunded? Then don't just accept: send the refund's date and amount, which resolves most conditions.
- Fraud codes: check whether the payment was authenticated with 3-D Secure, and whether earlier undisputed orders qualify for Compelling Evidence 3.0 on Visa 10.4.
- Accepting means the amount stays with the cardholder. Don't refund on top of it.
At pre-arbitration
If the issuer comes back with new information, accepting is usually the rational choice unless you have new, specific evidence that answers it. See pre-arbitration.
