(Delphi DLL) Create Signed SOAP XML for Albanian Fiscalization ServiceImportant: This example requires Chilkat v9.5.0.80 or greater. This example is created for a customer that needs to send signed billing/invoicing SOAP XML requests to http://efiskalizimi-test.tatime.gov.al:80/FiscalizationService The example demonstrates how to create and signed the SOAP XML message that is to be sent.
