API Testing
API (Application Programming Interface) Testing is a type of software testing that focuses on verifying the functionality, reliability, performance, and security of APIs — the backbone of modern web and mobile applications. Unlike UI testing, API testing is fast, stable, and highly effective for early-stage defect detection.
