Heya, I’m trying to determine if a person joined a game via an invite sent via socialservice, so I can give them rewards for joining via a game invite. Are we able to do that?
Thanks!

Basically after prompting you will have a connection which will run when the GameInvitePrompt gets closed.
We will use SocialService.GameInvitePromptClosed:Connect() for this.

-- Client:
local function gameInvitePromotClosed(player, recipientIds)
   -- send recipientIds to server
   Event:FireServer(recipientIds)
end

-- Server:
local PlayerService = game:GetService("Players")

local invitedIds = {} -- invite[playerInstance] = recipientIds

local function findId(Id)
   local playersWhoInvited = {}

   for playerWhoInvited, Ids in pairs(invitedIds) do
      if table.find(Ids, Id) then
         table.insert(playersWhoInvited, playerWhoInvited)
      end
   end

   return playersWhoInvited
end

local function mergeTables(t, t2)

   for _, v in ipairs(t2) do
      -- No repeated ids
      if not table.find(t, v) then
         table.insert(t, v)
      end
   end

   return t
end

local function onEvent(player, recipientIds)
   if invitedIds[player] then
      invitedIds[player] = mergeTables(invitedIds[player], recipientIds)
   else
      invitedIds[player] = recipientIds
   end
end

PlayerService.PlayerAdded:Connect(function(player)
   -- Have a check if both players are friended if they are not ban the player who sent the invite for exploiting; I won't add this
   local id = player.UserId

   local playersWhoInvited = findId(id)
   
   for _, playerWhoInvited in pairs(playersWhoInvited) do
      -- Reward player, you can give players less reward if multiple invited them:
      -- Reward * 1 / #playersWhoInvited 
   end
end)

PlayerService.PlayerRemoved:Connect(function(player)
--   invitedIds[player] = nil
end)

The scripts can be optimized in lots of ways this is just the basics.

Doesn’t that return a nil table now? [ENABLED as of May 28] SocialService Game Invites are Live
