Sending invoices to KSeF

The main part of the Tax Reporting function runs on the LSP. These must be sent to KSeF through the Web Services Gateway.

Note: To communicate with KSeF, you must provide the pfx and tax ID used to communicate with the tax authority portal. You can generate the pfx and certificates using the LSP Key Generator. See Generating certificate files using LSP Key Generator.
