Sorry , I am new in web api actually when I am running my API on postman the response is correct.but when i am implementing in code its giving internal server code error.

var gizmo = new Product() { ChannelId= "948404"};
HttpResponseMessage response = await client.PostAsJsonAsync("https://xxx-xxxxxx-api.xxx.co/api/bills, , gizmo);
if (response.IsSuccessStatusCode)
{
}

You can add headers like below:
httpClient.DefaultRequestHeaders.Add("HeaderKey", "HeaderValue");
You can also check how to user HttpClient in .net core (if you are using .net core) :

Rohit, after getting a result into jsonstring variable. in next line while deserrilzie jsonstring it's giving error:

"Message": "An error has occurred.",
"ExceptionMessage": "Cannot deserialize the current JSON object (e.g. {\"name\":\"value\"}) into type 'System.Collections.Generic.List`1[BBPSAXISWEBAPIEntity.Entity.CategoriesList]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly."

var jsonString = response.Content.ReadAsStringAsync().Result;
List idList = JsonConvert.DeserializeObject>(jsonString);

If you know the type of your output then you can use it like this:
response.Content.ReadAsAsync<YourTypeHere>().Result;
If you dont know the type then use dynamic and process the result
response.Content.ReadAsAsync().Result;
