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

How do we build a valid JWT token with the given payload `payload = {email: 'john@doe.org'}`?

How do we build a valid JWT token with the given payload <code>payload = {email: 'john@doe.org'}</code>?

An error `JWT::VerificationError` is raised.

`{a: 1}` is returned, but we get a warning in the console.

What happens if we try to use `JWT.decode` with an invalid signature?

For example, we define a token, `token = JWT.encode({a: 1}, 'bar')`, and then decode it as `JWT.decode(token, 'wrong')`.
