It’s probably a good idea to put your consumer’s OAuth token and

OAuth secret into your project’s settings.

TWITTER_TOKEN='my token '
TWITTER_SECRET='my secret’
consumer = oauth.Consumer(TWITTER_TOKEN,TWITTER_SECRET)
client = oauth.Client(consumer)

request_token_url = 'http://twitter.com/oauth/request_token

This is the slightly different URL used to authenticate/authorize.

authenticate_url = ‘http://twitter.com/oauth/authenticate

# Step 1. Get a request token from Twitter.
resp, content = client.request(request_token_url, “GET”)

# Step 2. Store the request token in a session for later use.

# Step 3. Redirect the user to the authentication URL.
url = "%s?oauth_token=%s" % (authenticate_url,

Hi – I’m having a very similar problem using twython_django_oauth, which has a workflow almost identical to the above. I can successfully create a user the first time the user successfully enters Twitter credentials. However, when the user tries to log in a second time, a new ‘oauth_token_secret’ is passed into the authenticate step rather than the secret token stored when the user authorizes through Twitter the first time. I can’t figure out why, based on the twython_django_oauth view very similar to the above, the stored secret token isn’t simply funneled into authenticate and an authenticated user logged in.
