refusalReason property
If the payment's authorisation is refused or an error occurs during authorisation, this field holds Adyen's mapped reason for the refusal or a description of the error. When a transaction fails, the authorisation response includes resultCode and refusalReason values. For more information, see Refusal reasons.
