How to Ace API Design Questions on Your Exam
Struggling with API Design? Here is the no-BS guide to understanding it, complete with real-world examples and study shortcuts.
Have you ever stared at a API Design problem and felt like you were reading another language? You aren't alone. Let's break down exactly why this trips up so many students.
Inside the Professor's Mind
Professors don't write API Design questions to test your basic memorization. They write them to test if you will fall for the classic pitfall: using GET requests to modify data.
When you sit down for the exam, write that specific trap at the top of your paper so you don't forget it.
What A Correct Answer Looks Like
GET requests can be cached by browsers and servers. If you use a GET request to delete a user (`/api/deleteUser?id=5`), a web crawler might accidentally delete your whole database.
If your scratch paper doesn't look like that, you are losing points.
