Integrated should provide a integrated-social-bundle with (as first) export connectors for the most important social networks.
The first will be Twitter.
Create the integrated-social-bundle (repo: https://github.com/integratedfordevelopers/integrated-social-bundle)
Create a Twitter export connector (http://www.integratedfordevelopers.com/content/documentation/article/creating-an-exporter-for-content-distribution)
You should be able to add a Twitter configuration which handles the API authorization
On export it will post: [title] [url]
While waiting for INTEGRATED-999, please hardcode the URL as: /content/article/[slug], using the primary domain of the primary channel
