request_token = oauthapp.get_request_token(callback)
# authorize request token
authorization_url =
oauthapp.get_authorization_url(request_token)
# refresh authorized request token with access token
access_token =
oauthapp.get_access_token(request_token)
oauthapp.token = access_token

profile = oauthapp.getProfile()
print profile
