Supplier Invoice File

Access supplier invoice files for your SMS platform. List available supplier invoice files and download specific documents for accounting, auditing, and financial reconciliation purposes.

List supplier invoice files first to discover the files available for a given supplier invoice, then use the returned file identifiers with the download operation to retrieve the actual document. Unlike the InvoiceFile resource, which downloads a document directly by DTS file type in a single call, SupplierInvoiceFile requires this two-step list-then-download flow since the available files and their identifiers aren't known in advance.
