PaymentService

General for almost all requests is that an invoice number (InvoiceNumber) is needed to handle the request. The invoice number is generated by Walley in the AddInvoice method and returned in the response. This invoice number needs to be stored (together with your order) for further request of that invoice, for example when handling returns.
