Think Like a Hacker: Pitfalls to Avoid When Writing an API

API security is crucial for modern applications. Key areas to focus on include strong authentication and authorization, thorough input validation, rate limiting, careful error handling, and regular updates. Implementing industry-standard protocols like OAuth 2.0, validating all inputs server-side, setting request thresholds, providing generic error messages, and keeping dependencies updated are essential practices. By anticipating potential exploits, developers can proactively secure their APIs, building trust with users and protecting against common vulnerabilities.
