using System.Net.Http;
using System.Text;
using System.Text.Json;
using System.Threading.Tasks;

public async Task SendLineNotificationAsync()
{
    using var client = new HttpClient();
    var payload = new
    {
        channelAccessToken = "YOUR_LINE_ACCESS_TOKEN",
        groupId = "YOUR_LINE_GROUP_ID",
        message = "แจ้งเตือนงานใหม่ในระบบ TeamWork!"
    };

    var content = new StringContent(
        JsonSerializer.Serialize(payload), 
        Encoding.UTF8, 
        "application/json"
    );

    var response = await client.PostAsync("http://localhost:5000/api/webhook/send", content);
    var resultStr = await response.Content.ReadAsStringAsync();
    // Process response...
}
