QuickBooks Web Connector error




The QuickBooks Web Connector (QBWC) is a go-between application that allows qbXML and qbposXML to pass between a Web-based application (implementing a standard Simple Object Access Protocol [SOAP]-based Web service interface) and QuickBooks financial software or QuickBooks Point of Sale. Because all communication is initiated by the Web Connector running on the system with QuickBooks, we avoid opening firewall ports. Communication with Web services can be automatically scheduled or simply be initiated at the user’s convenience.
