Create Signed SOAP XML for Albanian Fiscalization Service
See more XAdES Examples
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/FiscalizationServiceThe example demonstrates how to create and signed the SOAP XML message that is to be sent.
