WebClient client = WebClient.create(vertx);
OAuth2WebClient oauth2 = OAuth2WebClient.create(
    client,
    OAuth2Auth.create(vertx, new OAuth2Options(/* enter IdP config */)))
 
  // configure the initial credentials (needed to fetch if needed
  // the access_token
  .withCredentials(new TokenCredentials("some.jwt.token"));

It also offers an HTTP response caching facility.
