API testing offers several benefits over traditional user interface (UI) testing such as testing business logic in an automated and stable way, ensuring applications are bulletproof against unknowns, and validating connectivity, security and scalability of platforms. Many companies incorporate API testing into their continuous integration and deployment processes to reduce risks of functional problems before production. While manual testing is limited, API testing allows testing endpoints as soon as they are available to customers and shortens production cycles. Proper data-driven end-to-end API testing eliminates the need to virtualize entire production environments for precise testing.
