title: linkedin oauth request the access token
body: <p>I have a problem when trying to get the oauth_token and oauth_token_sceret from linkedin oauth api. I can get requestToken (1st request), but in the callback page (after the user approved the app) I'm trying to get the token and the secret but I always get 401 and it says the signature is invalid.
  I'm posting the following values to <a href="https://api.linkedin.com/uas/oauth/accessToken" rel="nofollow">https://api.linkedin.com/uas/oauth/accessToken</a>:
  - oauth_consumer_key
  - oauth_nonce
  - oauth_signature_method
  - oauth_timestamp
  - oauth_token
  - oauth_verifier
  - oauth_version</p>
  
  <p>as a side note i don't understand why I'm getting the verifier (I don't need the PIN since it's running in a browser) .
  The only way I was able to get the token and the secret was when I also post the "oauth_token_secret" I received in the 1st requrst (when I asked for requestToken).
  But I can't get this oauth_token_secret in the callback page.</p>
  
  <p>I found out you need to pass in the secret token you get in the first request for requestToken (1st request) to the access token and it is working.</p>
