API key, explained simply
A key that lets an app read (or trade on) your exchange account.
An API key lets a tool such as Coin Healer see your balances and orders without your password. You choose what it may do when you create it.
Make read-only keys wherever you can, and never give any app a key that can withdraw - Coin Healer refuses such keys.
