[HttpPost]

User user = new User

string json = JsonConvert.SerializeObject(user);

HttpClient client = new HttpClient();
string apiUrl = "https://api.example.com/users";

HttpContent content = new StringContent(json, Encoding.UTF8, "application/json");
HttpResponseMessage response = await client.PostAsync(apiUrl, content);

if (response.IsSuccessStatusCode)
