TL;DR: The payment needs the card security code and it was not sent. Collect CVC through the Adyen Card component, forward encryptedSecurityCode, and check your config if you expected CVC to be optional.

The exact error:

```text
14_029 - CVC is required for this payment but not provided
```

## The fix

1. Add the CVC field via the Adyen Card component so it is encrypted client-side.
   Expected: The component returns an encrypted security code.
2. Map the component output into paymentMethod without dropping the field.
   Expected: The outgoing request carries encryptedSecurityCode.
3. If you skip CVC for stored cards, confirm your config allows it for that shopperInteraction.
   Expected: Validation passes and the payment proceeds to authorization.

## When this applies

- Card payments return 14_029
- A custom card form was just built
- Stored-card payments started failing after a config change

## When it does NOT apply

- Your config deliberately skips CVC for the flow and Adyen still demands it (a config question, not this error)
- The CVC is present but wrong (that fails later at the issuer)
- Non-card payment methods

## Versions

Adyen Checkout API v68 through v71, Web Components v5 and v6.

## Why it happens

The CVC requirement comes from your Adyen risk and channel configuration. Adyen enforces it at validation time, so a request without the security code is rejected before authorization.

## Edge cases and pitfalls

- Some recurring setups require CVC on the first payment only
- Amex needs 4 digits while most cards need 3; length checks belong client-side
- If your risk rules require CVC, every payment path must collect it
