How can I call a web api in c# using HttpClient?

Question

So I am trying to call a api in my C# method and am not getting the response that I would be getting, if I called the api using postman or insomia.

public static async  Task GetObject()
        {
            var httpClient = new HttpClient();
            //var t = await httpClient.GetStringAsync("https://ipapi.co/json/");

            var y = await httpClient.GetAsync("https://ipapi.co/json/");


            var o = await y.Content.ReadAsStringAsync();

            var j = y.Content.ReadAsStringAsync();

        }

The api is getting my request but its not returning the right result. You should be getting this result. Click on this https://ipapi.co/json/

What am getting is this

{  
   "error":true,
   "reason":"RateLimited",
   "message":"Sign up for IP Address Location API @ https://ipapi.co"
}

But I don't get it, when am using postman

Maybe it's because you are reading the response twice? Either read as json or convert the string to json — dcg

Sidenote: your method name and variables are not very clear at representing their meaning. The method GetObject doesn't actually return any data, and if it did, "Object" doesn't tell you what sort of data it is. y, o, and j don't convey any information about the data they hold. — gunr2171

@gunr2171 I am first seeing if I can get any type of result that is correct, than I would parse the json into an object. — Jade

You need to add the user-agent header.

httpClient.DefaultRequestHeaders.Add("User-Agent", "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/535.1 (KHTML, like Gecko) Chrome/14.0.835.202 Safari/535.1");

Can you explain how this fixed it?

They are apparently rate-limiting non-browser requests. You would have to ask them.

Some APIs don't allow requests without this header. If you want more detailed explanation you need the ask the developers. When something works in the browser (or postman) but not with code this is the first thing I try.
