Your First Postman Request
For this demo, we’ll be using an API that allows us to get fake todos, comments, posts, users, etc.. Now, everytime you want to use an API, you need to understand how to use that API and the best way to start is always by looking at the API documentation. Any API out there that you want to use should have an API documentation that explains how to use that API.
The API that you will be using is called jsonplaceholder: https://jsonplaceholder.typicode.com/
