Exact Online

Payroll API

Exact Online assigns invoice status automatically (`open` by default) and ignores the `status` field on create — invoices are finalized/processed in Exact Online, not via the API.
Set VAT via `line_items[].tax_rate.code`; Exact derives the percentage from the code, so `line_items[].tax_rate.rate` is ignored on create.


To configure the shipping address for invoices, it is recommended to update the customer resource. If there is a need to change this property, modifying the customer information is advised.

Limit parameter for pagination is not supported for this resource.
