This course is a comprehensive tutorial that will teach you the best way to build your next API with Rails. You’ll learn to create a Rails API from scratch and to optimize and secure a Rails API. By the end of this course, you’ll have a full-fledged Rails API ready to be used.

Building your own API with Rails

When it comes to authentication tokens, the **JSON
Web Token (JWT)** is the standard. JWT is an open standard that allows the secure
exchange of tokens between several parties. 
# Components of a JWT token
Overall, a JWT token is composed of three parts:

• A **header** which is structured in JSON and contains the validity date
of the token.

• A **payload** which is also structured in JSON and can contain any data. In our case, it
will contain the identifier of the "connected" user.

• A **signature** which allows us to verify that our application has encrypted the token and is therefore valid.


Learn about the authentication tokens that we can use to secure a session.
