Hi Alvin, The error in that response tells me your signature is incorrect. Double check you are generating your signature using the algorithm described here: http://dev.twitter.com/auth#signing-requests
In particular I notice the parameters in your GET request are not in lexicographical order, and so I wonder if they may not be in order in your signature base string.
