As a developer who uses Cache as DB for a couple of projects, I'm using REST API's every time, knowing how to consume a resource from REST API, in my opinion, it's crucial to know how to consume external REST Api's using %Net.HttpRequest because it enables integration with modern web applications and services, and it's a crucial skill for a backend developer who loves and uses Cache as a DB.
What and who is %Net.HttpRequest
its just a class but this is the proper way of making request outside of the framework, this is just a simple class who provide HTTP methods like GET, POST and PUT and all
