why we use use client credential in api route

Return a 401 error due to Client Credentials

Client Credentials: In OAuth2, the client credentials grant type is used to obtain an access token for the client itself, rather than for a user. This grant type is typically used by client applications that are acting on their own behalf, rather than on behalf of a user. In Laravel, you can use the createToken method of the Laravel\Passport\ClientRepository class to create a new client and get the client credentials.

use Laravel\Passport\ClientRepository;

$clientRepository = new ClientRepository();
$client = $clientRepository->create(
    'My Client', 'http://example.com', true, false
);

$clientCredentials = [
    'client_id' => $client->id,
    'client_secret' => $client->secret,
];

Here's an example of how you could use client credentials, middleware, and prefix in an API route in Laravel 9:

1.Create a new middleware that will check for client credentials:
go

php artisan make:middleware CheckClientCredentials
Enter fullscreen mode Exit fullscreen mode

2.In the handle method of the middleware, you can check for the presence of the client credentials in the request headers and return a 401 error if they are not present:

public function handle($request, Closure $next)
{
    $clientId = $request->header('client-id');
    $clientSecret = $request->header('client-secret');

    if($clientId != 'YOUR_CLIENT_ID' || $clientSecret != 'YOUR_CLIENT_SECRET') {
        return response()->json(['error' => 'Invalid client credentials'], 401);
    }

    return $next($request);
}
Enter fullscreen mode Exit fullscreen mode

3.Register the middleware in the app/Http/Kernel.php file in the $routeMiddleware array:

protected $routeMiddleware = [
    ...
    'client' => \App\Http\Middleware\CheckClientCredentials::class,
    ...
];
Enter fullscreen mode Exit fullscreen mode

4.In the routes/api.php file, use the group method to group together routes that should be protected by the client middleware and have the api prefix:

Route::group(['middleware' => 'client', 'prefix' => 'api'], function () {
    Route::get('users', 'UsersController@index');
    Route::post('users', 'UsersController@store');
    Route::put('users/{id}', 'UsersController@update');
    Route::delete('users/{id}', 'UsersController@destroy');
});
Enter fullscreen mode Exit fullscreen mode

5.In this example, all routes within the group have the prefix api added to the beginning of the URI, so the GET /users route will be accessible at /api/users and the DELETE /users/{id} route will be accessible at /api/users/{id}. and all routes within the group will be protected by the client middleware, which will check for the presence of the client credentials in the request headers and return a 401 error if they are not present.

6.To access any of the routes in the group, you'll need to include the client-id and client-secret headers in your request with the correct values as set in the middleware.

Note: To use the client credentials, you should have a way to authenticate it and also protect your secret key from being exposed, you should use best practice to secure it.
