    The user has been redirected back from the provider to your registered
    callback URL. With this redirection comes an authorization code included
    in the redirect URL. We will use that to obtain an access token.

    NOTE: your server name must be correctly configured in order for this to
    work, do this by adding the headers at your http layer, in particular:
    X_FORWARDED_HOST, X_FORWARDED_PROTO so that bottle can render the correct
    url and links for you.
