Magento Commerce, 1.14.x
Facebook Open Graph

The Facebook Open Graph 2.0 extension enables Facebook developers to add custom social networking buttons to your store. The Facebook Open Graph 2.0 extension is free of charge and can be downloaded from Magento Connect.

The extension uses the Facebook Open Graph 2.0 protocol. When the extension is successfully installed and all configuration is complete, the Facebook buttons appear on each product page in the store, along with the Facebook blocks that provide information about other Facebook users and friends who have clicked the social buttons. The information provided in the blocks depends on the customer who is logged in to Facebook and whether friends have performed actions with your app, such as clicked a social button.
