Post a Json string in Xamarin

In my app, I am posting json string to the server in this manner:

string url = "my/url";
        HttpClient newClient = new HttpClient();

        string contentType = "application/json";
        JObject json = new JObject
        {
            { "id", "id" },
            { "apiKey", "apiKey" },
            { "EncryptedData", Data }
        };

        var jon = JsonConvert.SerializeObject(json);
        var content = new StringContent(jon, Encoding.UTF8, contentType);
        var TaskPostAsync = await newClient.PostAsync(url, content);


        if (TaskPostAsync.IsSuccessStatusCode)
        {
            var contentString = await TaskPostAsync.Content.ReadAsStringAsync();}

The response I am getting is that it is not in a Json format. Where am I going wrong. Any help would be much appreciated. Data is a string.

By calling 

 var jon = JsonConvert.SerializeObject(json);

You are serializing it twice.

JObject is already JSON so all you need to do is call .ToString to get the JSON

//...

JObject json = new JObject
{
    { "id", "id" },
    { "apiKey", "apiKey" },
    { "EncryptedData", Data }
};

var content = new StringContent(json.ToString(), Encoding.UTF8, contentType);

//...

Reference Write JSON text with JToken.ToString

Another option would be to use an anonymous object and then serialize that

//...

var model = new {
    id = "id",
    apiKey = "apiKey",
    encryptedData = Data
};

var json = JsonConvert.SerializeObject(model);
var content = new StringContent(json, Encoding.UTF8, contentType);

//...
