Application Programming Interface (API) Security is a critical aspect of modern software development, especially as APIs become the backbone of digital communication between applications. APIs enable systems, services, and devices to exchange data and functionality seamlessly, but this convenience also introduces security risks if not properly managed.

API security focuses on protecting the integrity, confidentiality, and availability of APIs. Common threats include unauthorized access, data breaches, injection attacks, and man-in-the-middle attacks. To mitigate these risks, developers implement security measures such as authentication, authorization, rate limiting, input validation, and encryption.

Authentication ensures that only verified users or systems can access the API, while authorization restricts their access based on permissions. OAuth 2.0 and API keys are commonly used for these purposes. Rate limiting helps prevent abuse and denial-of-service (DoS) attacks by controlling the number of requests a user can make. Additionally, input validation helps detect and block malicious data before it can exploit vulnerabilities.
