We need to create a Keycloak Client to communicate with it using either OpenID Connect or SAML protocol. Your application could use those client credentials to communicate with Keycloak.
In this tutorial we are going to create an OpenID Connect Client, and create a link to test the set up so you won't need to update your application just yet.
Create a client so we can send requests to Keycloak to start the authentication flow, in this case using the protocol OpenID Connect
Upon a successful authentication, users will be forwarded to the desired page. We need to white list that redirect URI. In this tutorial we are redirecting users to a mock page that is publicly available (http://mockbin.org/request)
