# PKPaymentErrorKey

Additional details about an error on the Apple Pay sheet.

## Declaration

```swift
struct PKPaymentErrorKey
```

## Discussion

Discussion Use payment error keys if you are creating a payment error without using one of the convenience methods in PKPaymentRequest (such as paymentBillingAddressInvalidError(withKey:localizedDescription:) or others). The payment error keys indicate a specific field that has an error, for example, the street field of an address.
