I am following The implicit OAuth 2.0 flow Guide:

My client ID is `4709` while key is `RoZwtHUrhMP088oVGCMlxA((`

I appended my url as 

    https://stackexchange.com/oauth/dialog?client_id=4709&scope=private_info&redirect_uri=https://stackexchange.com/oauth/login_success

and trying to oauth.

And I got this url as returned. 
`https://stackexchange.com/oauth/login_success#access_token=I*SJDoi6W(TUAz2BRCEzbw))&expires=86399`

I notice that `I*SJDoi6W(TUAz2BRCEzbw))` is the `access_token`.

When I try to call the request as [this answer of my question](http://stackapps.com/a/6300/33134) .

So I call

 `http://api.stackexchange.com/2.2/questions/30028657/answers?site=stackoverflow&key=RoZwtHUrhMP088oVGCMlxA((&access_token=I*SJDoi6W(TUAz2BRCEzbw))&filter=!%294k-FmUi-xgG3sdSdPz*cQNNqR0A`

Unfortunately, I got 403 Error,

`{"error_id":403,"error_message":"`key` is not valid for passed `access_token`, token not found.","error_name":"access_denied"}`

Any Idea?
