This is a webapi project written in visual studio and we will secure endpoint using JWT.

There is pre-requiste to implement OAUTH. you can learn about OAUTH here OAuth 2.0: The Definitive Guide

Basically, a JWT token look like:

<base64-encoded header>.<base64-encoded claims>.<base64-encoded signature>

JWT token has three sections:
