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.

The document we received details various upcoming known improvements to Xbox and the Universal Windows Platform (UWP) APIs developers will be able to use in their games, including dev optimizations to leaderboard systems, stat tracking, and various hardware analysis improvements. This in-game Clubs API for devs, however, is a new feature.
