postBooksScan method

Future<ScanDraft?> postBooksScan({ MultipartFile? body, })

Scan a receipt or invoice into a proposed voucher

Takes a receipt or invoice as RAW BYTES — a PDF, an image or plain text, uploaded under its own content type, not wrapped in JSON — extracts what the document says, resolves the vendor's expense category, and answers a DRAFT carrying a balanced voucher proposed for it. NOTHING IS POSTED. That split is the whole design: the model only ever produces a structured reading of the document, the voucher is assembled deterministically in Go from that reading, and the ledger is written only by the separate book call a human confirms. So a misread scan can propose a wrong draft; it cannot move money. Amounts are exact integer cents end to end — the extraction returns cents, never a decimal — so no rounding enters the ledger. The draft's id is the FILE HASH, and that is what makes booking idempotent: re-scanning the same bytes addresses the same draft rather than queuing a second one. A row is written to the org's document inbox as a side effect, moving it from unsorted to draft. Scoped to the caller's own org from the validated principal and refused without one; sandbox=true targets the sandbox ledger, and filename is recorded for the inbox. An empty or oversized upload is a 400, and a deployment with no scanner model answers 501.

Parameters:

• MultipartFile body:

Implementation

Future<ScanDraft?> postBooksScan({ MultipartFile? body, }) async {
  final response = await postBooksScanWithHttpInfo( body: body, );
  if (response.statusCode >= HttpStatus.badRequest) {
    throw ApiException(response.statusCode, await _decodeBodyBytes(response));
  }
  // When a remote server returns no body with a status of 204, we shall not decode it.
  // At the time of writing this, `dart:convert` will throw an "Unexpected end of input"
  // FormatException when trying to decode an empty string.
  if (response.body.isNotEmpty && response.statusCode != HttpStatus.noContent) {
    return await apiClient.deserializeAsync(await _decodeBodyBytes(response), 'ScanDraft',) as ScanDraft;

  }
  return null;
