Detailed Description

Invoke named trigger events that grant server-configured rewards.

Triggers are created in the console and linked to reward payloads (assets, currency, progression points). Limited Triggers may be invoked at most N times per player — ideal for one-time milestones, achievements, or first-launch gifts. Unlimited Triggers can be invoked repeatedly for recurring rewards such as per-kill drops or ad-watch grants. Rewards are automatically granted to the player's inventory and wallets.

See the LootLocker documentation.

Function Documentation

◆ InvokeTriggersByKey()

static FString ULootLockerSDKManager::InvokeTriggersByKey	(	const TArray< FString > &	KeysToInvoke,
		const FLootLockerInvokeTriggersByKeyResponseDelegate &	OnComplete,
		const FString &	ForPlayerWithUlid = `""`
	)

static

Invoke triggers by key.

The response includes lists of executed trigger keys and failed triggers (with reasons); a successful request may still contain failures—inspect inner results.

Parameters

KeysToInvoke	Trigger keys to invoke
OnComplete	Delegate for handling the server response
ForPlayerWithUlid	Optional: Execute for the specified player ULID (default player if empty)

Returns: A unique id for this request, use this to match callbacks to requests when you have multiple simultaneous requests outbound
