如何在c#中使用Pushwoosh Web API向特定用户发送推送通知

我想使用Pushwoosh Web API向一些订阅者广播推送通知。

我一直在使用他们网站上给出的代码

但是它正在发送给所有注册用户。如何只向特定用户发送通知?

以下是JSON生成代码:

string pwAuth = "YOUR_AUTH_TOKEN";
       string pwApplication = "PW_APPLICATION_CODE";
       JObject json = new JObject(
           new JProperty("application", pwApplication),
           new JProperty("auth", pwAuth),
           new JProperty("notifications",
               new JArray(
                   new JObject(
                       new JProperty("send_date", "now"),
                       new JProperty("content", "test"),
                       new JProperty("wp_type", "Toast"),
                       new JProperty("wp_count", 3),
                       new JProperty("data",
                           new JObject(
                               new JProperty("custom", "json data"))),
                       new JProperty("link", "http://pushwoosh.com/"),
                       new JProperty("conditions",
                           new JArray(
                               (object)new JArray("Color", "EQ", "black")))))));
       PWCall("createMessage", json);

谢谢

 string[] arr = new string[1];
 arr[0] = "9d48ac049ca6f294ea25ae25f3472b0e7e160ba06729397f9985785477560b3a";
 JObject json = new JObject(
           new JProperty("application", pwApplication),
           new JProperty("auth", pwAuth),
           new JProperty("notifications",
               new JArray(
                   new JObject(
                       new JProperty("send_date", "now"),
                       new JProperty("content", new JObject(new JProperty("en", pushContentEnglish), new JProperty("es", pushContentSpanish))),               
                       new JProperty("data", new JObject(new JProperty("custom", new JObject(new JProperty("t", notificationType), new JProperty("i", objectId))))),
                       new JProperty("devices", new JArray(arr))
                       ))));
