Validating APIs for functionality, performance, and security.

API testing verifies the functionality, reliability, and security of application programming interfaces (APIs) using tools like Postman or RestAssured. It ensures APIs handle requests correctly, return accurate data, and perform under load, critical for modern web and mobile applications.

• Ensures reliable and secure API performance.
• Validates data accuracy and request handling.
• Supports microservices and API-driven apps.
• Scalable for high-traffic environments.
• Integrates with automation tools.
