C# API call Assistance

I am in the process of changing one of our API calls

The current call is in the format 

[url]/[user]/[itemid]

The new call is in the format:

[url]
{
 "user": ["user"],
 "category": ["category"],
 "itemIds": ["itemid1"], ["itemid2"]
}

In C# I currently build up the request as follows:

        string requestUrl = string.Format(_url, _userID, _itemID);

        HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(requestUrl);
        string password = GetSignatureHash();

        request.Method = "GET";
        request.ContentType = "application/json";
        request.Accept = "application/json";
        request.Headers["Authorization"] = "Basic " + password;

        HttpWebResponse response = (HttpWebResponse)request.GetResponse();

Please can someone advise me on how to populate the new HTTP Request with the detail given above?

Any assistance, advice or links would be greatly appreciated.

You should use Json.NET as a serializer and write to the request stream. You should have a class that mirrors your data structure for your request. E.g.

public class MyRequest
{
    [JsonProperty("user")]
    public int User { get; set; }
    [JsonProperty("category")]
    public int Category { get; set; }
    [JsonProperty("itemIds")]
    public IList<string> ItemIds { get; set; }
}

HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(_url);
string password = GetSignatureHash();

request.Method = "POST";
request.ContentType = "application/json";
request.Accept = "application/json";
request.Headers["Authorization"] = "Basic " + password;

using (var streamWriter = new StreamWriter(request.GetRequestStream()))
{
    var myRequest = new MyRequest { User = 1, Category = 1, 
                                    ItemIds = new[] { "1", "2" } };

    streamWriter.Write(JsonConvert.SerializeObject(myRequest));
    streamWriter.Flush();
}

HttpWebResponse response = (HttpWebResponse)request.GetResponse();

The request sent will be like:

{
  "user": 1,
  "category": 1,
  "itemIds": [
    "1",
    "2"
  ]
}
