Understand Apis . Learn basic working of Apis . Improve reading capability to understand Api documentation . Learn Api testing tools. Apply testing techniques Verify data

- debugging skills will help in understanding the API's better way - analyze the dev tools always - check the network tab in dev tool of the browser to monitor the api calls - understand the api contracts and headers, param, payload, auth types, etc.. - lot of tools are available in market Postman is best one to start with

To excel in API testing, one needs a blend of technical skills, including proficiency in programming languages (e.g., Python, Java, C#), familiarity with API testing tools (e.g., Postman, SoapUI, RestAssured), knowledge of testing frameworks (e.g., PyTest, TestNG, JUnit), and understanding of various testing techniques (functional, load, security, contract testing) and API documentation standards (Swagger, RAML, OpenAPI). Additionally, essential soft skills include effective communication for teamwork and reporting, analytical abilities for creating test scenarios, problem-solving skills for addressing challenges, and a commitment to continuous learning to stay updated on API testing trends and practices.
