For void and other vantiv calls, I can see the request/response XML from those requests here: https://github.com/Vantiv/litle-sdk-for-java/blob/6f4ff6835bc16169ceeb27b73b5cf06f5ed48c07/src/main/java/com/litle/sdk/Communication.java#L128 Is there a way on how to see the XML request/responses when doing an `echeckCredit `?
