Facebook provides a global payments platform that is available internationally and supports 80+ payment methods in 55+ currencies. PlayFab has integrated with Facebook Payments, so players can pay for items in your game using their existing Facebook credentials.
How it Works
To use Facebook Payments, you will need your Facebook App ID, and developer secret. You get these when you setup your app in Facebook. Detailed instructions are provided in the support link. Note that you do not need to install this add-on in order to use the Facebook social graph for social leaderboards — that feature is enabled by linking a player’s Facebook credentials to their profile.
