API keys are used to authenticate users and identify what account is being accessed by an automated program. With APIs, traders can use 3rd party services to execute trades, manage their portfolios, collect data on their accounts, and implement complex strategies. There are two important elements included in a set of API keys; the public key and the private key. These are sometimes also referred to as the public key and secret key. When requesting access to a trader’s account, the program will use the secret key to sign requests. This tells the exchange that the program has the authorization to access the trader’s exchange account and perform the operations that are supported by the API key.
