Exercise 1 – GET request

The link below provides an exercise that uses the Nager.Date public Web API that we discussed in the Using APIs section:

https://github.com/HackYourFuture/Learning-Resources/tree/main/core-program/week-9/public-holidays

It consists of a pre-made web application with just one part waiting for you to complete: fetching data from the Web API. For this, you will need to study the documentation of the Nager.Date web API. Full instructions are given in the README of the example.

Exercise 2 – Using Postman

In this exercise, we will use a pre-made custom backend application to practice GET, POST, PUT, and DELETE requests. Visit the link below and follow the Getting started section in the README.

https://github.com/HackYourFuture/Learning-Resources/tree/main/core-program/week-9/simple-api

Exercise:

  1. Read the API documentation and use Postman to test each of the given API endpoints.
  2. For each request, observe the output logged in the terminal that is running the backend and compare it to the response you see in Postman.

Exercise 3 – Authentication
