What does Adyen refusal reason 31 “Issuer Suspected Fraud” mean?

Checked

Adyen refusal reason 31, "Issuer Suspected Fraud", means the card issuer reported the transaction as suspected fraud. Adyen's raw responses list 59 Suspected fraud, and 34 Suspect fraud for Mastercard. The shopper should confirm the purchase with their bank before trying again. Blind retries ask the same fraud model the same question.

Type
Soft decline (fraud signal)
Who declined
The shopper's card issuer
Retry
Not automatically. Visa lists 59 in category 2, but only a shopper-present, authenticated retry makes sense.
Shopper action
Confirm the purchase with the bank, then try again.
Merchant action
Do not retry off-session; review the order.

What PlatformDTC does

PlatformDTC does not connect to Adyen; its checkout runs on Stripe and PayPal. An issuer fraud refusal reaches it as Stripe's do_not_honor over raw Visa 59; PlatformDTC never retries that renewal, and at checkout reroutes it only with 3D Secure on the backup processor.

Why it happens

The issuer's fraud model did not like the transaction: an unusual location, amount, merchant type or pattern.

What the shopper can do

Approve the transaction in your banking app or call the bank, then pay again; or use another card.

What the store can do

Never retry silently. If the order looks genuine, ask the shopper to confirm with their bank and pay again with 3D Secure.
