In addition to providing authentication services out of the box, Lumen also provides a simple way to organize authorization logic and control access to resources. There are a variety of methods and helpers to assist you in organizing your authorization logic.

In general, authorization can be used in Lumen the same way it is used in Laravel. We will cover a few differences here, but you should refer to the full Laravel documentation for additional details.

Differences From Laravel

Defining Abilities

The primary difference when using authorization in Lumen compared to Laravel is in regards to how abilities are defined. In Lumen, you may simply use the Gate facade in your AuthServiceProvider to define abilities:

Gate::define('update-post', function ($user, $post) {
    return $user->id === $post->user_id;

Defining Policies

Unlike Laravel, Lumen does not have a $policies array on its AuthServiceProvider. However, you may still call the policy method on the Gate facade from within the provider's boot method:

Gate::policy(Post::class, PostPolicy::class);

Again, to learn more about policies, you should consult the full Laravel documentation.

Checking Abilities

You may "check" abilities just as you would in the full Laravel framework. First, you may use the Gate facade. If you choose to use the facade, be sure to enable facades in your bootstrap/app.php file. Remember, we don't need to pass the User instance into the allows method since the currently authenticated user will automatically be passed to your authorization callback:

if (Gate::allows('update-post', $post)) {

if (Gate::denies('update-post', $post)) {

Of course, you may also check if a given User instance has a given ability:

if ($request->user()->can('update-post', $post)) {

if ($request->user()->cannot('update-post', $post)) {
