BigCommerce API-无法获取产品列表

很明显，我在这里缺少了一些明显的东西。我认为使用OAuth v2查询BigCommerce API会很容易……然而，我得到的响应是：｛"error"："您已获得授权，但您的范围不包括此资源。"｝

正在使用的令牌是从Auth回调返回的，其范围为：store_v2_orders store_v2_products store_v_2_customers store_v2_content store_v2_marketing store_v2_information_read_only users_basic_information store_v2_default

显然，令牌具有适当的范围。我发送的内容不正确，导致无法访问？我已经搜索了所有的互联网络，并尝试了许多替代配置，但这一配置感觉最接近解决方案。有什么想法吗？

string storeID = "store-abc123";
string clientID = "asdfdsafsdafdsafdsaf";
string token = "kljsdflkjsdflkjsdflkj";
var client = new RestClient( "https://api.bigcommerce.com/" );
var request = new RestRequest( "/stores/" + storeID + "/v2/products/", Method.GET );
request.AddParameter( "scope", "store_v2_products" );
request.AddHeader( "Accept", "application/json" );
request.AddHeader( "X-Auth-Client", clientID );
request.AddHeader( "X-Auth-Token", token );
var response = client.Execute( request );

string storeID = "store-abc123";

string storeID = "abc123";
