API Penetration Testing (API Pentesting) in cybersecurity refers to the practice of testing Application Programming Interfaces (APIs) for vulnerabilities and security weaknesses. Since APIs are critical for enabling communication between different software systems, securing them is essential to ensure the confidentiality, integrity, and availability of data.
APIs are increasingly used in web and mobile applications to allow them to interact with each other, exchange data, and provide additional functionalities. However, if not properly secured, APIs can be exploited by attackers to access sensitive data, modify system behavior, or launch attacks.
