square connect api webhook更新错误

Question

我正在

{"type":"bad_request","message":"Unexpected token }"}

来自Update Webhooks端点的

。我正在尝试在asp.net中实现它。我的代码块如下：

        var httpCLient = new HttpClient();
        httpCLient.BaseAddress = new Uri("https://connect.squareup.com");
        AuthenticationHeaderValue auth = new AuthenticationHeaderValue("Bearer", "access_token");
        httpCLient.DefaultRequestHeaders.Authorization = auth;
        httpCLient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
        HttpContent content = new StringContent("{\"PAYMENT_UPDATED\"}", System.Text.Encoding.UTF8, "application/json");
        Task<HttpResponseMessage> httpResponse = httpCLient.PutAsync("/v1/me/webhooks", content);
        if (httpResponse.Result.StatusCode == HttpStatusCode.OK)
        {
        }

任何人都可以帮我吗？我已经在Google上搜索了任何连接API实施指南/示例，但没有运气。

发生此错误是因为请求的事件类型列表必须是JSON数组，而不是JSON对象。

如果您在上面的示例中将{\"PAYMENT_UPDATED\"}更改为[\"PAYMENT_UPDATED\"]，请求应该会成功。
