I've read through the documentation and I don't understand how to get the new code, I was doing this to get a token to read the feed for a site I'm an admin on:

> 
> <https://graph.facebook.com/oauth/access_token?client_id=>" + sClientID + "&client\_secret=" + sSecret + "&redirect\_uri=" + sRedirectURI + "&code=" + sCode;
> 
> 
> 

and then:

> 
> "<https://graph.facebook.com/>" + sUser + "/accounts?" + sToken; 
>  To get the feed.
> 
> 
> 

It's telling me: 

```
{
  "error": {
    "message": "This authorization code has been used.", 
    "type": "OAuthException", 
    "code": 100
  }
}

```

I know I need a new authorization code but cannot find the method to call to get one in the documentation. Alternatively, is there another way to get this feed?
