Best Practices for Securing APIs: A Comprehensive Guide

In the ever-evolving landscape of technology, securing APIs (Application Programming Interfaces) is of paramount importance. APIs serve as the backbone for communication between different software systems, making them a prime target for attackers. Adopting best practices for API security is crucial to protect sensitive data, ensure data integrity, and maintain the trust of users and stakeholders. Let's explore some essential best practices for securing APIs.
