(JavaScript) Hungary NAV Manage Invoice Request

Demonstrates the manageInvoice request for the Hungarian NAV Online Invoicing System REST API v2.0.

Note: This example requires Chilkat v11.0.0 or greater.

For more information, see https://onlineszamla.nav.gov.hu/api/files/container/download/Online%20Szamla_Interfesz%20specifik%C3%A1ci%C3%B3_EN_v2.0.pdf

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

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