Use Case: Buying Courses on Educative

Since we have an understanding of the Square SDK, let's experience it in a simple use case of e-learning.

Assume that you're looking for a new job opportunity and want to equip yourself with some trendy skill set. You find out that you should learn system design and React development. You explore the internet, and land on Educative, where you find the courses of your choice. You'll need to follow the steps below to buy those courses:

1. Create an order

2. Generate an invoice

3. Make a payment
