(Xojo Plugin) Create Signed SOAP XML for Albanian Fiscalization Service

Important: 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.

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// --------------------------------------------------------------------------------
// Also see Chilkat's Online WSDL Code Generator
// to generate code and SOAP Request and Response XML for each operation in a WSDL.

// We want to build and send a signed SOAP XML that looks like the following:
