Slack recently introduced app unfurling - https://medium.com/slack-developer-blog/all-will-be-revealed-ebcad7c531f0#.cbzhgw3bk. Normally when you link to a Metorik page in Slack, it won't show much in the 'link preview'. This is because Slack doesn't have permission to see anything in the link.
With the new feature introduced by Slack, Metorik can let Slack see some data about the link when it's posted your channel.
So imagine you posted a link to a Metorik customer profile in Slack. This new feature will let Slack get the customer's data to show in the link preview.
Pretty neat, right?
