API Authentication

API authentication is the security process that verifies the identity of a user or application attempting to access an exchange's API. It ensures that only authorized parties can place trades, view account data, or manage sensitive information.

Common methods include API keys, secret keys, and digital signatures. API keys serve as a unique identifier, while secret keys are used to sign requests, proving that the request originated from the authorized owner.

This process protects against unauthorized access and prevents malicious actors from manipulating accounts. Robust authentication is a fundamental requirement for secure trading.

It involves storing keys securely and implementing best practices, such as IP whitelisting and regular key rotation. API authentication is a critical component of a secure trading environment.

It allows traders to interact with exchanges confidently while maintaining the integrity of their accounts.
