In my Windows desktop app if i call "https://api.twitter.com/1.1/users/lookup.json?user_id=?" with one user id then it works fine, but while providing a list of user id’s it just throws me the 401 error.

I am passing the user id’s list as a comma separated strings(as described in the documentation).

Please help me to solve this issue.

Verify that your comma encoding is correct. Some OAuth or HTTP libraries may munge the encoding on commas.
