Tools for REST APIs
When you explore and test API endpoints, you will use one of the many graphical user interface (GUI) REST clients available to make API requests. You will also use a command-line interface, like cURL for some tasks too.
Swagger UI is used to explore and learn about APIs using the OpenAPI specification. Many developers also use Postman for testing and development, but there are plenty of choices out there that will work with the platform REST APIs.
