Can't get toon ID -> presence ID in Battle.net functions?

[Foxthorn]

So in 5.4.7 Blizzard added some Battle.net functions to allow sending invisible addon data. However, there doesn't seem to be any way to take a Battle.net toon presence ID (which identifies a specific character on your BN friends list) and get the presence ID of the actual BN friend who owns that character.

BN_CHAT_MSG_ADDON returns four values - addon prefix, text, “WHISPER”, and senderToonID.
senderToonId, as far as I can tell, cannot be used directly to interact with or get information about a BN friend. Meaning you can't even respond to a BN_CHAT_MSG_ADDON with a BNSendGameData(presenceID)...

BNGetToonInfo(toonID) returns a presence ID (as its last return value), but it's the toon ID, not the friend's presence ID... Is there something I'm missing or can you really not convert a toon ID to a presence ID? Am I going to have to iterate over every single BN friend and check if each one's current toon ID matches the toon ID returned by BN_CHAT_MSG_ADDON?

BNGetToonInfo seems to literally return whatever value you give it, making its final return value completely pointless.

If BNSendGameData works like BNSendWhisper, then you can use the presence and toon IDs interchangeably to send messages.

However, if you do need the presence ID from the toon ID you can loop over online friends with BNGetFriendInfo or BNGetFriendToonInfo and compare the toon IDs or just watch the BN login events and keep a reference table of [toonID] = presenceID.

edit: I just tested it and you can use either the presence ID or the toon ID with BNSendGameData.

Okay, thanks for confirming that. I mainly want to show the real name in BN_CHAT_MSG_ADDON so I guess I'll have to loop through BNGetFriendInfo and look for the one with the correct toonID.

You should probably implement a cache of some kind so you're not running that loop every time you receive a message. I'd use a metatable:

local nameFromToonID = setmetatable({}, { __index = function(t, k)
    local _, numFriends = BNGetNumFriends()
    for i = 1, numFriends do
        local _, presenceName, _, _, _, toonID = BNGetFriendInfo(i)
        if toonID == k then
            t[k] = presenceName
            return presenceName
        end
        -- Remove this inner loop if you don't have any friends who multibox under a single Battle.net account
        for j = 1, BNGetNumFriendToons(i) do
            local _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, toonID = BNGetFriendToonInfo(i, j)
            if toonID == k then
                t[k] = presenceName
                return presenceName
            end
        end
    end
end })
 
-- Look up like so:
local presenceName = nameFromToonID[toonID]
