question

Currently adding friends in PlayFab is a one way process. Players can add other players to their own friend list without the needs of other players’ confirmation.

There is a workaround to implement two-way friend confirmation with Cloud Script:

1. Player 1 selects to send a friend request to Player 2
2. Use AddFriend on both players, setting each in the other player's friend list
3. Use SetFriendTags on both players, to tag the players uniquely ("requester"/"requestee", or similar)
4. Title uses Push Notification (via Cloud Script) and/or Photon Chat to send notification to the other player
5. A CloudScript example of above is:

handlers.SendFriendRequest
      = function(args, context){ 
      server.AddFriend( 
      { 
      PlayFabId: currentPlayerId, 
      FriendPlayFabId: args.FriendPlayFabId 
      }); 
      server.SetFriendTags({ PlayFabId:
      currentPlayerId, 
      FriendPlayFabId: args.FriendPlayFabId, 
      Tags: ["requestee"] 
      }); server.AddFriend( 
      { 
      PlayFabId: args.FriendPlayFabId, 
      FriendPlayFabId: currentPlayerId 
      }); 
      server.SetFriendTags( 
      { 
      PlayFabId: args.FriendPlayFabId, 
      FriendPlayFabId: currentPlayerId, 
      Tags: ["requester"] 
      }); server.SendPushNotification({ 
      Recipient: args.FriendPlayFabId, 
      Message: "Nice to meet you" 
      });}

• Player 2 sees the Push, or the Chat, or finds the friend request upon login (using GetFriendsList, checking for the "requester" tag)
• Player 2 accepts or declines the friend request
• If Player 2 accepts, either remove the tags from both players or set them to something like "confirmed", a CloudScript example is:

• handlers.AcceptFriendRequest
        = function(args, context){ 
        server.SetFriendTags({ PlayFabId:
        currentPlayerId, 
        FriendPlayFabId: args.FriendPlayFabId, 
        Tags: ["confirmed"] 
        }); 
        server.SetFriendTags( 
        { 
        PlayFabId: args.FriendPlayFabId, 
        FriendPlayFabId: currentPlayerId, 
        Tags: ["confirmed"] 
        });}

• If Player 2 declines, remove each player from the other player's friend list, a CloudScript example is:

• handlers.DenyFriendRequest
        = function(args,context){ server.RemoveFriend({ PlayFabId:
        currentPlayerId, 
        FriendPlayFabId: args.FriendPlayFabId, 
        }); 
        server.RemoveFriend( 
        { 
        PlayFabId: args.FriendPlayFabId, 
        FriendPlayFabId: currentPlayerId, 
        });}
