Creating a LinkedIn app and configuring authentication in Auth0

This method is used mainly when the authentication mechanism is actually performed somewhere else, either on your own server or another SaaS provider. In this case, you will be using Auth0 to provide the LinkedIn authentication. You could have performed the Facebook, Twitter, or Google authentication via Auth0 as well.
