The Xbox Clubs system will be opened up to developers so they can create in-game systems, according to leaked documents.
Microsoft unveiled Xbox Clubs in late 2016 as a way to create social groups on Xbox Live. Using the Xbox One itself or various Xbox apps, players can now set up and manage their own "Clubs," complete with membership systems, a common chat room, and a Facebook-like social feed for sharing screenshots, clips, and status updates.

Targeting an April launch, developers will soon be able to access a new tool, or application programming interface (API), that will let them leverage Xbox Live's Club system in their games, according to official Xbox developer documentation leaked to Windows Central. Developers will be able to use the API to create structures such as clans and multiplayer guilds, and then sync them to Xbox Live.
