ItemLocation
ItemLocation is used to reference items by their container position:
local itemLoc = ItemLocation:CreateFromBagAndSlot(0, 1)
local itemLoc = ItemLocation:CreateFromEquipmentSlot(INVSLOT_HEAD)
if itemLoc:IsValid() then
local name = C_Item.GetItemName(itemLoc)
end
Item Data Loading (ContinuableContainer)
local item = Item:CreateFromItemID(12345)
item:ContinueOnItemLoad(function()
local name = item:GetItemName()
local link = item:GetItemLink()
local icon = item:GetItemIcon()
print(name, link)
end)
Batch Loading
local container = ContinuableContainer:Create()
for _, itemID in ipairs(itemIDs) do
local item = Item:CreateFromItemID(itemID)
container:AddContinuable(item)
end
container:ContinueOnLoad(function()
end)

Iterate All Bag Items

for slot = 1, C_Container.GetContainerNumSlots(bag) do
local info = C_Container.GetContainerItemInfo(bag, slot)
if info then
print(info.hyperlink, info.stackCount, info.quality)
end
end
end
Count Free Bag Slots
local totalFree = 0
for bag = 0, 4 do
local free = C_Container.GetContainerNumFreeSlots(bag)
totalFree = totalFree + free
end
print("Free slots:", totalFree)
Check If Player Has Item
local count = C_Item.GetItemCount(12345, true)
if count > 0 then
print("You have", count, "of this item")
end
Auto-Sell Junk at Vendor
for bag = 0, 4 do
for slot = 1, C_Container.GetContainerNumSlots(bag) do
local info = C_Container.GetContainerItemInfo(bag, slot)
if info and info.quality == Enum.ItemQuality.Poor then
C_Container.UseContainerItem(bag, slot)
end
end

Gotchas & Restrictions
- Async item data —
C_Item.GetItemInfo() may return nil for uncached items. Use C_Item.RequestLoadItemDataByID() and listen for GET_ITEM_INFO_RECEIVED, or use the Item:ContinueOnItemLoad() mixin pattern.
- Bag index 5 — In Retail, bag index 5 is the Reagent Bag slot, not a bank bag.
- Account Bank — Account bank tabs (Warband bank) use
Enum.BagIndex.AccountBankTab1..5 (indices 13–17). Check C_PlayerInfo.IsAccountBankEnabled().
- GetMerchantItemInfo removed — Use
C_MerchantFrame.GetItemInfo(index) in 12.0.0.
- Protected functions —
EquipItemByName, UseContainerItem, and similar functions may be restricted during combat lockdown.
- Item secrets — In 12.0.0 instances, some item-related data may become secret values. Design UIs to pass values directly to widgets.
- ContainerInfo structure —
C_Container.GetContainerItemInfo() returns a table with fields: iconFileID, stackCount, isLocked, quality, isReadable, hasLoot, hyperlink, isFiltered, hasNoValue, itemID, isBound.
