API testing is a type of software testing that involves directly testing application programming interfaces (APIs) to verify their functionality, reliability, performance, and security. Unlike traditional software testing, API testing doesn’t focus on the user interface. Instead, it sends requests to the API, receives responses, and validates whether the responses are correct based on the API’s specifications. This includes verifying data integrity, error handling, and response times. Common API testing techniques include functional testing, load testing, security testing, and penetration testing. Tools like Postman, REST-assured, and SoapUI are frequently used to automate and streamline the testing process.
