What is an API automation testing?

An API Automation Testing job involves designing, developing, and executing automated test scripts to verify the functionality, reliability, and performance of application programming interfaces (APIs). Testers use tools like Postman, RestAssured, or SoapUI to validate API requests and responses. They ensure seamless integration between software components, detect defects early, and improve test efficiency. Strong knowledge of programming, API protocols (REST, SOAP), and test frameworks is essential.
