Accessing Twitter Without User Interaction

I'm writing some scripts for my boss that reads a specific user's tweets over the course of a week, and then dumps them into a formatted Tumblr post. Because he wants 开发者_JAVA百科this done automated, I'm using cron to run the scripts periodically, but this is not the point of the post.

My question is, since the move to OAuth by the Twitter API, is user interaction necessary to get credentials?

It's not if you can get your application approved for xAuth by Twitter.
