What is Rest API testing?

A REST API Testing job involves verifying the functionality, reliability, performance, and security of RESTful web services. Testers use tools like Postman, REST Assured, or JMeter to send requests, validate responses, and ensure API endpoints behave as expected. Responsibilities include writing test cases, automating API tests, identifying issues, and working closely with developers to resolve defects. This role is crucial for ensuring seamless integration between front-end and back-end systems in software applications.
