What is an api tester?

An API Tester is responsible for evaluating application programming interfaces (APIs) to ensure they function correctly, securely, and efficiently. They design, execute, and automate test cases to validate API responses, performance, and error handling. API testers use tools like Postman, SoapUI, or REST Assured and may work with RESTful and SOAP APIs. Their role is crucial in identifying bugs and ensuring seamless communication between software components.
