OAUTH2 Not Authorized error

[StephenH5]

I am going through the steps to get my OAUTH2 access token. The first part works fine and I get back the code and username. When I try to use the code I get a 401 - Not Authorized error. Here is the code I am using.

string auth = "https://oauth2.constantcontact.com/oauth2/oauth/token?grant_type=authorization_code&client_id=APIKEY... from first step&redirect_uri=https://173.168.9.110:83/Home";

HttpWebRequest request = HttpWebRequest.Create(auth) as HttpWebRequest;

request.Method = "POST";

WebResponse response = request.GetResponse();
Stream respStream = response.GetResponseStream();
StreamReader reader = new StreamReader(respStream);
string text = reader.ReadToEnd();

// Clean up the streams.
reader.Close();
respStream.Close();
response.Close();

Hey,

The 401 would be issued for a few reasons.  If you recieved this 401 erorr  more than a handful of times it is a good possibility that you are locked out of your account.  Otherwise, you may be passing in the credentials incorrectly.  You can pass them through the authorization headers as

Authorization: Bearer the_token

 You can read more about this here.

Please let me know if this helps.
