This library helps to build a HTTP service very quickly with embedded serialization and deserialization. You just need create interface, mark HTTP methods with attributes (GET, POST, DELETE etc.) and Poster will create your interface implementation for you.

    public interface IOrderService
    {
        [Get("https://test.com/order/{id}")]
        public Task<Order> GetOrderAsync(int id);

        [Post("https://test.com/order")]
        public Task CreateOrder([Body] Order order);
    }

            var poster = new PosterBuilder()
                // Here you can add build configuration
                .Build();

            var orderService = poster.BuildService<IOrderService>();
            var order = await orderService.GetOrderAsync(10);

Poster support all main request types: GET, POST, PUT, PATCH, DELETE. You need to mark your method in service interface via GetAttribute, PostAttribute, PutAttribute, PatchAttribute or DeleteAttribute accordingly. Each http attribute has constructor with url parameter. Service will do request to this url addres. Url supports inline parameters. Parameter should be covered in bracket {} and method should contains this parameter as argument with the same name.

        [Get("https://test.com/order/{id}")]
        Task<Order> GetOrderAsync(int id);

        [Post("https://test.com/message/{testParam}?param={param}")]
        Task<Message> CreateMessageAsync(string testParam, double param);

Each method in your service should returns Task or Task<TResponseModel>.

If you want to send request body, you can add it to your method as argument and mark it via BodyAttribute

        [Post("https://test.com/order")]
        Task CreateOrderAsync([Body] Order order);

Warning: only POST, PUT, PATCH methods support request body.
