Postman is one of the most popular collaboration platform tools for testing APIs (Application Programming Interfaces) available to install on Linux, Windows, and macOS. Well, APIs are interfaces between programs that the applications use to communicate with one another.
The main area of ​​the application is testing REST APIs based on HTTP requests that can be specified and sent in Postman with associated parameters using the visual request builder.
