I successfully retrieved an OAuth token then immediately execute the C# code below. I get this exception. What am I doing wrong?

```
   Response: WebException: The remote server returned an error: (401) Unauthorized.

   HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://api-sandbox.dwolla.com/");         
    request.ContentType = "application/vnd.dwolla.v1.hal+json";
    request.Accept = "application/vnd.dwolla.v1.hal+json";
    request.Headers.Add("Authorization", "Bearer " + Token.Access_token);
    var response = (HttpWebResponse)request.GetResponse();
    String responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
    return responseString;
```

Hi @rtiktin, As part of this request are you specifying the request method? i.e. `request.Method = "GET";`

I do want to point out that we released a C# client library awhile back which has undergone some recent updates. I’d recommend taking a look at it [here](https://github.com/Dwolla/dwolla-v2-csharp) to see if it could be useful.

Hi Spencer,

I tried adding request.Method = “GET”; but I’m still getting:  
WebException: The remote server returned an error: (401) Unauthorized.

I downloaded the C# example but can’t use it because it uses a higher version of C#.

The only other possible issue I see here could be that Access\_token should instead be `access_token`. Thanks for the feedback on the C# client library, we’ll see if we can update that to support a lower version of C#!
