Approach Contexts[edit]
The approach context (in the form of an encrypted payload) of the console can be retrieved using FRDU:GetMyApproachContext.
Encrypted payloads can be decrypted using FRDU:DecryptApproachContext.
It is possible to add a friend using an encrypted payload using FRDU:AddFriendWithApproach.

Notification Events[edit]
The friends module exposes a "Notification Events" system that allows client sessions to be notified of various related events.
A client sets its per-session notification event signaling handle using FRDU:AttachToEventNotification.
The client can then customize for which Notification Event Types it shall receive notifications using FRDU:SetNotificationMask.
Once the handle has been signaled by the friends module, the client can use FRDU:GetEventNotification to receive the notifications.

Relationship Types[edit]
Every valid entry in the internal friends list contains a relationship field.
| Value
|
Description
|
| 0
|
The target has been added locally and on the server, but is only "provisionally registered." The target has not added you as a friend.
|
| 1
|
The target has been added locally and on the server and is fully registered: the target has also added you as a friend.
|
| 2
|
No relationship between you and the target has been found: neither you nor the target have added each other.
|
| 3
|
The relationship has been deleted: the target has deleted your friend card.
|
| 4
|
The target has been added locally: you were not online when you added the target. (presumably only happens when the "Local" method of adding a friend is used. When the system connects to the internet, a background task runs to register this relationship on the friends server.)
|
Attribute Flags[edit]

Server Types[edit]
The server type is stored internally as a combination of two values, the first value represents the server type letter and the second value is the number that follows it. For example, the production server type is "L1", so the first value is 0 and the second value is 1.
Official servers only support the letters L, C, S, D, I, T, J or U.
