I am unable to get user information from twitter api


I am getting this error

{“errors”:[{“message”:“Bad Authentication data”,“code”:215}]}

when i call the http request from my windows8 store app like this

https://api.twitter.com/1.1/users/show.json?user_id=” + userid;

here i am using azure service for twitter login, it returns the user id and accesstocken from twitter after, but when i pass the user id to that service api it giving the following error
"errors":[{“message”:“Bad Authentication data”,“code”:215}]}


I’m not familiar with any login services for Azure. What have you tried so far to debug?
