Get the Vat zones applicable Vat Id's -Get /controller/api/v1/vatZone/{vatZoneId} 3. Get the invoice lines Vat categories applicable Vat Id's -Get /controller/api/v1/vatCategory/{taxCategoryId} 4. The Vat Id needs to be a value found in both lists. - Get /controller/api/v1/vat/{vatId} Can you point us towards where to set up the Visma.NET account so its possible to export to it?  ... View more
