What is API testing? The complete guide (2026 update)
API testing is a software testing practice that validates application programming interfaces directly at the message and logic layer, rather than through a user interface. It checks that endpoints return correct responses, handle errors, enforce security, and perform reliably under load, verifying functionality, data integrity, and reliability before an application reaches production. API testing operates…
