How can I get the notifications that I accidentally cleared from notification box?

[AC Question]

I usually check the notifications on my Samsung Galaxy Note 10.1 (also known as GT-N8010) to see what it is but I accidentally deleted or cleared it from the box and now I cannot get it. Please help me and thank you.

Open the app the notification is from and you should be able to figure out what it was. (You can't make the app create the notification again.)
