updateInvoice method

Future<Invoice> updateInvoice({ required int invoiceId, required UpdateInvoiceRequest request, String? authToken, })

Updates an invoice by modifying fields, clearing fields, or both.

For most updates, you can use a sparse Invoice object to add fields or change values and use the fields_to_clear field to specify fields to clear. However, some restrictions apply. For example, you cannot change the order_id or location_id field and you must provide the complete custom_fields list to update a custom field. Published invoices have additional restrictions.

Implementation

Future<Invoice> updateInvoice({
  required int invoiceId,
  required UpdateInvoiceRequest request,
  String? authToken,
}) async {

  authToken ??= authenticationService.getCachedToken()?.accessToken;

  Map<String, String> headers = {
    "Authorization": "Bearer ${authToken ?? ""}",
    'Content-Type': 'application/json; charset=UTF-8',
    'Accept': 'application/json',

  };

  Uri endpoint = Uri.https(
      baseUrl, "/v2/invoices/$invoiceId");

  //print (endpoint.toString());

  var response = await
  http.put(endpoint, body: jsonEncode(request.toJson()), headers: headers);

  if (response.statusCode == 200) {
    print (jsonDecode(response.body));
    return InvoiceResponse.fromJson(jsonDecode(response.body)).invoice!;
  }
  else {
    print (response.body);
    throw InvoiceException(statusCode: response.statusCode, message: InvoiceResponse.fromJson(jsonDecode(response.body)).errors?[0].detail?.toString());
  }
}
