When i call the CreatePaymentAsync and get an exception.
How do you parse the exception in C#. My test case is an invalid CCV.

The APIException.Errors is -

[0] = {Error : (Category = PAYMENT_METHOD_ERROR, Code = VOICE_FAILURE, Detail = Authorization error: ‘VOICE_FAILURE’, Field = null)}
[1] = {Error : (Category = PAYMENT_METHOD_ERROR, Code = CVV_FAILURE, Detail = Authorization error: ‘CVV_FAILURE’, Field = null)}

APIException.Errors is a List
The List can be traversed without converting to Json.
