,"error":"Not authorized" when attempting to get tweet from user with hashtag

I am attempting to get all tweets fro a specific user with a hashtag. The url I am using is: https://api.twitter.com/1/statuses/user_timeline.json?q=%23jdmr%2Bfrom%3ABarrySpang which without the URL encoding is simply: https://api.twitter.com/1/statuses/user_timeline.json?q=#jdmr+from:BarrySpang When I try it in twitter search (as stated in the API docs) and it displays the desired results, however when I try the above URL I get a 401 response with this error message: {"request":"/1/statuses/user_timeline.json?q=%23jdmr%2Bfrom%3ABarrySpang","error":"Not authorized"} Please can you advise me on this
