Incorporate API requests into your end-to-end tests and validate responses, including the status code, headers and body (JSON/Text) values. API steps are also great for working with test data without having to interact with the UI of the application. For example, you can use an API step to create multiple customer records in your application and then delete those records in another API step at the end of the test plan.
