Creating a Postman collection with requests

Postman is a free client tool in a graphical format that can be installed on any type of OS. Its role is to test APIs through requests, which we will organize into collections. It also allows us to dynamize API tests through the use of variables and the implementation of environments. Postman is famous for its ease of use, but also for the advanced features that it offers.
