Sending InvoiceData to NAV

Communication with the tax authorities, or NAV, is through the Web Services Gateway.

You must also have NAV (Nemzeti Adó és Vámhivatal) credentials that connects to the API of NAV. Refer to the NAV website for information on how to create and connect to their API.

For on-premise installations, firewall exceptions should be added for the webservice endpoints.

Alternatively, you can use the third-party connector to switch to Web Services Gateway.
