Please configure the logger in DEBUG mode and capture the raw request and response XML. Without that it is hard to find the exact issue. It could because of some non XML characters which is present in the XML(API Payload) and that's why serialization is failing.

You can try ApiExplorer tool to test this. https://developer.intuit.com/apiexplorer?apiname=V3QBO
