What do you need to know to work with the API?

Question

API

It may seem like a stupid question. But what do you need to work with a variety of site APIs (github, discord, etc.). That is, what technologies should I use in my work. Why not use pure get post requests? And if you can give a short example, it's very short. What would I drive into the basic principles.

Answer 1

Download Postman
