Retrofit is a Type Safe REST client for Android Developed by square. It uses okHttp library for HTTP requests, and it's one of the best tools for performing network requests in android applications. In this video I'll show you how to send POST request. For those of you who are not familiar with POST request. Basically POST is used to send data to a server to create/update a resource. The data sent to the server with POST request is stored in the request body of the HTTP request and not in the URL!

Retrofit requires three main components:
1. Retrofit Instance:
We can create an instance of Retrofit by Retrofit.Builder class. And we have to specify the base url and converter factory at the time of the Retrofit instance creation

2. Model Class:
Retrofit needs a Model class for sending and receiving Request. It uses the model class for parsing server Response by using converters like Gson, Moshi etc.

3. An Interface for possible API calls:
The interface contains methods that represents possible API calls. Each methods need a base Url end point annotation that represents the Http methods like GET, POST etc.
