An example of client code and XML response from LinkedIn's network_updates endpoint. The access tokens used have requested the rw_nus permission.

python-linkedin.py

from linkedin import linkedin
import config


li = linkedin.LinkedIn(config.Linkedin.API_KEY, config.Linkedin.API_SECRET, 'http://foo.com')

"""the network_updates endpoint needs rw_nus permission, so do something like this during oauth flow:
li.request_token(['rw_nus', 'r_fullprofile'])
"""

li._access_token = config.Linkedin.OAUTH_TOKEN
li._access_token_secret = config.Linkedin.OAUTH_SECRET

print li.network_updates(scope='self', types=['CONN', 'SHAR'], count=2)
