You need to create a c# object using data first. then you need to serialize that object eg var json = JsonConvert.SerializeObject(data);

Now all you need to do is pass the string to the post method.

var stringContent = new StringContent(json, UnicodeEncoding.Utf8, "application/json");

var client = new HttpClient(); var response = await client.PostAsync(uri, stringContent);
