Check Grant Notifications

To check items granted to the player from outside sources such as Loot boxes, you can periodically call the check grant notifications endpoint.

Along with details on what assets have been granted to the player it's also possible to see which source they were granted from

Unity

LootLockerSDKManager.GetAssetNotification((response) =>
{
    if (response.success)
    {
        Debug.Log("Successfully check asset notifications");
    }
    else
    {
        Debug.Log("Error checking asset notifications");
    }
});
