I’m calling the users lookup method  to fetch a list of users who are following me. When I call this method with exactly one user_id or screen_name, everything works fine, which seems that the oauth code is ok.
When there are more than one (as in the example call on ) I get an authorisation error code 32.
I get a list of ids from the followers/ids method, and I concatenate each in a loop with the comma as delimiter before I call users/lookup.
Has someone an idea? I’m using the Qt Oauth library for authentication in version 1.0.
