Note: scoped_to=none retrieves Promoted-Only Tweets. Use the followers value to retrieve organic Tweet data.
A Tweet URL is structured as follows: https://twitter.com/{screen_name}/status/{Tweet ID}. You can construct this with the data included in the response. The id attribute is the Tweet ID.
Hope this helps.
