Question about making requests on a url to find new submissions?

Hi, this might be the wrong place to ask but I'm very new to anything related to this. I'm trying to figure out how I could find new submissions on a specific url/page. For example, I would have a script running on a twitter account and everytime that specific twitter account tweets, it would notify me(?) or just spot it(?). Is this possible and is this the right place to ask? If yes, where would I start about learning how to do this?Thanks a lot
