api bug

hi. on the mana api (get users current playtime), GET request, it says the parameter of 'authorization header key' is required. where can i get one?

Yesterday, after completing two quests, I should have earned 3 quest points which I did not get any, but I received the other rewards though (reward chests, vote key, rare enchantment book). I would really appreciate to have my quest points back, I took a long time to complete them. All of this...
