Common Patterns

Iterate Quest Log

local numEntries, numQuests = C_QuestLog.GetNumQuestLogEntries()
for i = 1, numEntries do
    local info = C_QuestLog.GetInfo(i)
    if info and not info.isHeader then
        local questID = info.questID
        local title = info.title
        local isComplete = C_QuestLog.IsComplete(questID)
        print(title, isComplete and "(Complete)" or "")
    end
end

Track/Untrack Quest

local function ToggleQuestWatch(questID)
    if C_QuestLog.IsQuestWatched(questID) then
        C_QuestLog.RemoveQuestWatch(questID)
    else
        C_QuestLog.AddQuestWatch(questID, Enum.QuestWatchType.Automatic)
    end
end

World Quests on Map

local function GetWorldQuestsOnMap(uiMapID)
    local quests = C_TaskQuest.GetQuestsForPlayerByMapID(uiMapID)
    if quests then
        for _, quest in ipairs(quests) do
            local title = C_TaskQuest.GetQuestInfoByQuestID(quest.questId)
            local timeLeft = C_TaskQuest.GetQuestTimeLeftMinutes(quest.questId)
            print(title, timeLeft and (timeLeft .. " min left") or "")
        end
    end
end

Quest Completion Event Handling

local frame = CreateFrame("Frame")
frame:RegisterEvent("QUEST_TURNED_IN")
frame:RegisterEvent("QUEST_ACCEPTED")
frame:RegisterEvent("QUEST_REMOVED")
frame:SetScript("OnEvent", function(self, event, ...)
    if event == "QUEST_TURNED_IN" then
        local questID, xpReward, moneyReward = ...
        print("Completed quest:", C_QuestLog.GetTitleForQuestID(questID))
    elseif event == "QUEST_ACCEPTED" then
        local questID = ...
        print("Accepted quest:", C_QuestLog.GetTitleForQuestID(questID))
    elseif event == "QUEST_REMOVED" then
        local questID, wasReplayQuest = ...
        print("Quest removed:", questID)
    end
end)

Gotchas & Restrictions

Quest data may not be loaded — Call C_QuestLog.RequestLoadQuestByID(questID) and wait for QUEST_DATA_LOAD_RESULT before accessing quest info for quests not in the log.
GetInfo returns headers — Quest log entries include headers (zones). Check info.isHeader to filter.
Quest watch limit — There's a maximum number of tracked quests. AddQuestWatch() returns false if at limit.
Auto-accept quests — Some quests auto-accept. Check QuestGetAutoAccept() to handle gracefully.
World quest vs regular — World quests use C_TaskQuest functions, not C_QuestLog for map display.
Quest gossip flow — Quest accept flow: QUEST_GREETING → QUEST_DETAIL → AcceptQuest() → QUEST_ACCEPTED.
Campaign quests — Use C_CampaignInfo.IsCampaignQuest() to identify story quests.
Objective data — GetQuestObjectives() returns a table with text, type, finished, numFulfilled, numRequired per objective.
