You can achieve this using RSS feeds and some third party middleware that pulls the RSS feed and pushes to your social media accounts.
Have a look at RSS Feeds.
Zapier is a middleware tool that allows you to easily integrate your TARGETconnect RSS feeds with a wide range of social media platforms including Twitter, Facebook, Google+ and many more.
1. Create an RSS feed on TARGETconnect and make a note of the feed URL.
2. Create an account on Twitter or Facebook or have your existing account details handy.
3. Create an account on Zapier (up to 5 connectors are currently free).
4. Add the RSS and Twitter zaps.
5. Add the RSS URL.
6. Add the Twitter account details and authorise.
7. Zapier will process and confirm success.
The TARGETconnect support team cannot support Zapier but can help you setting up RSS feeds if you are having problems. Look at the Zapier help and support for more information.
