Title Body

I'm working in the sandbox and using the PayPal REST .net SDK method Payment.Create with a CreditCard object. When all parameters are valid and using the test CC number from https://developer.paypal.com/webapps/developer/docs/integration/direct/accept-credit-cards/ , the Payment object is returned from that method and all is well. However, when a parameter is not valid, such as a past expiration date or a CC number not recognized by the sandbox, the Payment object is not returned. Instead the method throws an exception: "Exception in HttpConnection Execute: Invalid HTTP response The remote server returned an error: (400) Bad Request", but with no further explanation. When I execute the same request in cURL, in addition to the "400 Bad Request", I get a JSON response. This includes more helpful messages such as "VALIDATION_ERROR" and "Invalid expiration (cannot be in the past)". My question: Is there a way to get these messages back from the SDK? What I've tried: PayPal docs: https://developer.paypal.com/webapps/developer/docs/api/#errors This document mentions that in the case of an error, they return the details in the body of the response. Unfortunately, it doesn't give a clue about whether these are accessible by the SDK. Various Google and SO searches. The PizzaApp sample code provided with the SDK has nothing in the way of exception handling or further insight into this problem. I see a PayPalException object in the SDK, but have not found anything that indicates how it should be used or if it's even relevant to this problem. All help is much appreciated.
