Consuming method POST

Retrofit is a very powerful library for making requests using HTTP verbs and that can be configured using Java annotations.

In this example we will explore the post method, first add following dependences in the grade file.

implementation 'com.squareup.retrofit2:retrofit:2.4.0'

Add the internet permissions in AndroidManifest.xml:

<uses-permission android:name="android.permission.INTERNET" />

JSONPlaceholder is a free online REST API that you can use whenever you need some fake data.
