What does Adyen refusal reason 24 “CVC Declined” mean?
Checked
Adyen refusal reason 24, "CVC Declined", means the specified card security code (CVC) is invalid. Adyen's raw responses list N7 Decline for CVV2 failure behind this kind of refusal. The shopper should re-type the 3-digit code on the back, or 4 digits on the front for American Express. Resubmitting the same wrong code only adds failed attempts.

What PlatformDTC does
PlatformDTC does not connect to Adyen; its checkout runs on Stripe and PayPal. The same answer arrives as Stripe's incorrect_cvc; PlatformDTC adds a plain hint to check the code, never retries it on renewals and never reroutes it, because the shopper has to fix it.
Why it happens
The issuer compared the security code with its records and it did not match, usually a typo or an autofilled old value.
What the shopper can do
Look at the card and type the security code again. Use the 4-digit code on the front for American Express.
What the store can do
Allow a correction, but a string of CVC failures on different cards from one source can mean someone is guessing.
