Can customers share purchases to Facebook?

This would be an awesome addition to our app. However, we're unable to pre-fill share text for customers as this is against Facebook's terms of service. 

Facebook's policy is designed to make sure that all Facebook posts are generated by the user, not pre-filled by an app. While customers can share a link to their Thank You or Order Confirmation page, we cannot pre-populate this post with their purchase details.

For more details, Buffer has a good overview of this update to Facebook's terms. Should their policy change in the future, we'll be keen to integrate this feature!
