Found a solution. For query string you have to add it to both the http_headers dictionary AND to the URL when making the Request.
<h2>old line:</h2> http_headers = {} http_headers['oauth_version'] = '1.0' <h2>new line:</h2> http_headers = {} http_headers['date'] = 'ddmmyyyy' #add this line http_headers['oauth_version'] = '1.0' <h2>old line:</h2> req = urllib2.Request(base_url) <h2>new line:</h2> req = urllib2.Request(base_url + '?date=ddmmyyyy') -- https://mail.python.org/mailman/listinfo/python-list
