Use the adjust endpoint with the location ID and inventory item ID to increase or decrease the available quantity for an inventory level: Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  final http = CkHttp();

  http.login = 'SHOPIFY_PRIVATE_API_KEY';
  http.password = 'SHOPIFY_PRIVATE_API_KEY';

  // Also see: How to retrieve inventory levels

  http.accept = 'application/json';

  // The following JSON is sent in the request body:

  // {
  //   "location_id": 6884556842,
  //   "inventory_item_id": 12250274365496,
  //   "available_adjustment": 1

  final jsonRequestBody = CkJsonObject();
  jsonRequestBody.updateInt('location_id', 6884556842);
  jsonRequestBody.updateInt('inventory_item_id', 12250274365496);
  jsonRequestBody.updateInt('available_adjustment', 1);

  final url = 'https://{shop}.myshopify.com/admin/api/2020-04/inventory_levels/adjust.json';

  final resp = CkHttpResponse();
  try {
    http.httpJson('POST', url, jsonRequestBody, 'application/json', resp);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  print('Response Status Code: ${resp.statusCode}');

  final jsonResponse = CkJsonObject();
  jsonResponse.load(resp.bodyStr);
  jsonResponse.emitCompact = false;
  print(jsonResponse.emit());

  if (resp.statusCode >= 300) {
    print('Failed.');
