API

The Roanuz Definition: Imagine you are at a restaurant, and you want to order a meal. Now you can’t just walk straight into the kitchen and cook yourself the meal, right? You convey what you want to the waiter, who will take your order to the kitchen, and he brings back your food.
The waiter plays the exact role of an API, acting as a middleman between different software applications, which helps them communicate and exchange information. Having an API is like having a waiter who can speak multiple languages and understands what the customers order, and delivers the food without any hassle.
Now let's have a look at some of the common examples of APIs:
REST API
REST (Representational State Transfer) APIs are one of the most common ways for computers to talk to each other through the Internet. It's like having a waiter at a restaurant who gets you what you want. With a REST API developers can ask a server for the information and they will get it back in a way that they can understand, just like a special menu created for computers known as JSON.
With this, the developers can figure out how to use the APIs themselves without having to look into every detail or information. In simple terms, it’s like having a book with all the recipes you want, instead of inventing all the dishes from scratch.
GraphQL
This is a newer API technology which has become increasingly popular amongst the developers’ community. With the help of GraphQL, you can specify exactly the data you need, and the API will return that data in just a single response. Multiple requests must be sent to a REST API which is less efficient compared to this API which can be used even for complex structures as you can request and get only the required data.
