Welcome to Friends (Beta)
The Friends service allows you to boost player engagement by providing players with a social system that works well with other Unity services. With Friends, your players can:
Environments are logical partitions of Unity Game Services that contain data associated with your project. You can set the target environment in the Friends Dashboard and your initialization scripts. Refer to Unity Environments.
The Friends service manages relationships of different types. In general, most user relationships don’t change often; however, there are updates users often want to know about as soon as possible. To increase efficiency, the Friends SDK fetches all a user’s relationships one time at startup, then keeps the list up-to-date using push notifications.

- A member with a
TARGETrole (the receiver).
However, the members role changes to

The SDK provides some wrapper APIs for specific operations to increase the service’s usability.
For example, when you call the

CreateRelationship API and creates a new

If there’s already a
FRIEND_REQUEST relationship from the target user, it creates a new
FRIEND relationship. Depending on the state,
SendFriendRequestAsync can result in a
FRIEND_REQUEST or a new
