Use Laravel API from another Laravel-instance

Hello everybody,

I would like to ask you for articles on how to consume a Laravel API (I will call this Laravel Proviider) from another external Laravel instance (I will call this Laravel Client).

The Setup

The Laravel Provider is providing the API-routes for it's own vue/vuex/vue-router based frontend. To archive this, I integrated laravel/passport.

After running php artisan passport:install on the Laravel Provider I added the generated client id and the secret to .env to consume it in my LoginController like this:

        $request = Request::create('/oauth/token', 'POST', [
            'grant_type'    => 'password',
            'client_id'     => config('services.vue_client.id'),
            'client_secret' => config('services.vue_client.secret'),
            'username'      => $request->email,
            'password'      => $request->password,
        ]);

I guess I could authenticate users on the Laravel Client this way, too.

Open question

• How do I allow the Laravel Client to access Laravel Server's API routes?
• How do I create a second passport client without overwriting the others?
