How to display message

you can use like this also

var body = new JavaScriptSerializer().Serialize(objShippingOrdr);
var client = new RestClient("https://api.nimbuspost.com/v1/shipments");
client.Timeout = -1;
var request = new RestRequest(Method.POST);
request.AddHeader("content-type", "application/json");
request.AddParameter("application/json", body, ParameterType.RequestBody);
var response = client.Execute(request);

if (response.StatusCode == HttpStatusCode.OK)
    Console.WriteLine("Success");
else
    Console.WriteLine(string.Format("Failed. Code : {0}", response.StatusCode));

// you can use like below
if (response.IsSuccessful)
    Console.WriteLine("Success");
else
    Console.WriteLine(string.Format("Failed. Code : {0}", response.StatusCode));

Try this

private ApiResponse Shipments(ShippingOrdr objShippingOrdr)
{
    try
    {
        var body = new JavaScriptSerializer().Serialize(objShippingOrdr);
        var client = new RestClient("https://api.nimbuspost.com/v1/shipments");
        client.Timeout = -1;
        var request = new RestRequest(Method.POST);
        request.AddHeader("content-type", "application/json");
        request.AddParameter("application/json", body, ParameterType.RequestBody);
        var response = client.Execute(request);

        var apiResponse = new ApiResponse
        {
            StatusCode = response.StatusCode,
            Message = JsonConvert.DeserializeObject(response.Content).Message
        };
        return apiResponse;
    }
    catch (Exception ex)
    {
        var apiResponse = new ApiResponse
        {
            StatusCode = HttpStatusCode.InternalServerError,
            Message = ex.Message
        };
        return apiResponse;
    }
}

Response class

public class ApiResponse
{
    public HttpStatusCode StatusCode { get; set; }
    [JsonProperty("message")]
    public string Message { get; set; }
}

use like below

var result = Shipments(objShippingOrdr);
if (result.StatusCode == HttpStatusCode.OK)
{
    // code for success message
}
else
{
    // code for failure
}

Hi Ramco,

You should be able to read the content of your response. That is where you get to know everything. Your response will give you status with some message. You can also use try catch to catch unexpected runtime error. Please check below code for your reference. I have attached screenshot also to give you idea about how the response looks like.

            var message = "";
            try
            {
                var objShippingOrdr = new ObjectShipping
                {
                    Name = "Test",
                    Address = "Somewhere",
                    City = "New York"
                };
                var body = new JavaScriptSerializer().Serialize(objShippingOrdr);
                var client = new RestClient("https://api.nimbuspost.com");
                var request = new RestRequest("/v1/shipments", Method.Post);
                request.Timeout = -1;
                request.AddHeader("content-type", "application/json");
                request.AddParameter("application/json", body, ParameterType.RequestBody);
                var response = client.Execute(request);

                if (response.ResponseStatus == ResponseStatus.Error)
                {
                    message = "Your custom message";

                    //or alternative way
                    message = JsonConvert.DeserializeObject(response.Content).Message;
                }
            }
            catch(Exception ex)
            {
                message = "Your custom message";

                //or alternative way

                message = ex.Message;
            }

    public class ObjectShipping
    {
        public string Name { get; set; }
        public string Address { get; set; }
        public string City { get; set; }
    }

    public class ErrorMessage
    {
        [JsonProperty("message")]
        public string Message { get; set; }
    }
