I am sending request to an API but in response I am getting this JSON payload:

{"status":{"code":450,"message":null},"response":null}

Using browser that API works fine but with xmlhttprequest using C# its returning error. Can anyone help me understand if an API returning data on a browser but not with programming what could be the reasons.
Thanks in advance.
Here is URL "https://www.atea.dk/eshop/products/skaerme-og-projektorer/skaerme/"

string API = "https://www.atea.dk/eshop/nodeapi/get-products";
string json = new JavaScriptSerializer().Serialize(new
{
    nextPage = 2,
    url = "https://www.atea.dk/eshop/products/skaerme-og-projektorer/skaerme/"
};
using (var client = new WebClient())
{
    client.Headers.Add("Content-Type", "application/json");
    string result = client.UploadString(API, "POST", json);
}

What I have tried:

I have tried everything the best of my knowledge but seems that some headers from this API which I am missing. I am thankful if any help I can get.

If 450 is an http code then that means "Blocked by parental controls". Anyway, use a tool like Fiddler to examine the call when it is made by the browser vs the call when it is made by your code. Chances are the browser is adding a lot more header information and you need to work out which header is missing from your code. It might be as simple as the user agent, the accept type and so on. You won't know until you look.

I have tried again but no luck. Could you please help me here.

I can't access your system, I can't analyse the traffic to see how the two calls are different. Update your original question with the full request details of both calls and maybe someone can spot an important difference.

If you can help to find headers the browser is sending to the server and then I can compare with header I am sending in my requests i.e.
nextPage = 2,
url = "https://www.atea.dk/eshop/products/skaerme-og-projektorer/skaerme/"

I just tried the API call and it returns error code 449. You need to contact the owners of the website for assistance.

Its an ecommerce website everyone can access it. I am wondering if a browser can successfully bring data why not through xmlhttprequest.

Makes no difference what it is, you still need to formulate your request according to the site rules.
