Twitter API returned a 401 (Unauthorized), Invalid or expired token

Similar to this comment by hako, I get an 401 error trying to access the timeline. In a later comment he writes that it was caused by a problem with his access token and that he fixed it. But he does not explain how.

Here is what I have tried:

from twython import Twython
APP_KEY = 'XXX'
APP_SECRET = 'XXX'

twitter = Twython(APP_KEY, APP_SECRET)
auth = twitter.get_authentication_tokens()
OAUTH_TOKEN = auth['oauth_token']
OAUTH_TOKEN_SECRET = auth['oauth_token_secret']
print auth['auth_url']  
# I manually open this url in the browers and
# set oaut_verifier to the value like seen below.
oauth_verifier = u'xxxx'
twitter = Twython(APP_KEY, APP_SECRET, OAUTH_TOKEN, OAUTH_TOKEN_SECRET)

final_step = twitter.get_authorized_tokens(oauth_verifier)

OAUTH_TOKEN = final_step['oauth_token']
OAUTH_TOKEN_SECERT = final_step['oauth_token_secret']

twitter = Twython(APP_KEY, APP_SECRET,
                  OAUTH_TOKEN, OAUTH_TOKEN_SECRET)

And this is the error message:

twitter.verify_credentials()

TwythonAuthError: Twitter API returned a 401 (Unauthorized), Invalid or expired token

The twython version is:

In [70]: twython.__version__
Out[70]: '3.1.2'

Try this, I modified your code a bit,

from twython import Twython
APP_KEY = ''
APP_SECRET = ''

twitter = Twython(APP_KEY, APP_SECRET)

auth = twitter.get_authentication_tokens()

OAUTH_TOKEN = auth['oauth_token']

OAUTH_TOKEN_SECRET = auth['oauth_token_secret']

print auth['auth_url']

# I manually open this url in the browers and
# set oaut_verifier to the value like seen below.

oauth_verifier = raw_input('Enter your pin:')

twitter = Twython(APP_KEY, APP_SECRET, OAUTH_TOKEN, OAUTH_TOKEN_SECRET)

final_step = twitter.get_authorized_tokens(oauth_verifier)

FINAL_OAUTH_TOKEN = final_step['oauth_token']
FINAL_OAUTH_TOKEN_SECRET = final_step['oauth_token_secret']

twitter = Twython(APP_KEY, APP_SECRET,
                  FINAL_OAUTH_TOKEN, FINAL_OAUTH_TOKEN_SECRET)

print twitter.verify_credentials()

Sorry I didn’t elaborate my issue, it was saving the access token using pin based oauth.

This should work for you 😃
