how can i protect laravel api calling from other website

Access-Control-Allow-Origin https://mydomain.com/

 added a new middleware

<?php

namespace App\Http\Middleware;

use Closure;

class VerifyAPIAccess
{
    /**
     * Handle an incoming request.
     *
     * @param \Illuminate\Http\Request $request
     * @param \Closure $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if (
            !(App::environment('local'))
            && (
                !$request->header('access-token')
                || $request->header('access-token') !== env('APP_API_TOKEN')
            )
        ) {
            return response()->json(['Message' => 'You do not access to this api.'], 403);
        }

        return $next($request);
    }
}

and then added to my route

Route::group([
    'middleware' => [
        VerifyAPIAccess::class,
 	'throttle:60,1'
    ]
], function () {

// list some routes

});

you could also restrict access by adding throttling which would stop someone from hammering your API, with token or not.

There are probably many approaches. A simple but effective one would be sessions. You can save the user in a session. This way you can also count his Api accesses. As soon as they are larger than allowed, you can block their requests. You also write the block in the session. But pay attention to the session duration. It must be long enough.

But the user with bad intentions can get a new session. To avoid this, you can also put his IP on an internal blacklist for a day.

Note: But an open api is always a point of attack.

Things tried:

• Using passport to protect my routes and then use passport’s CreateFreshApiToken middleware. Protection works fine, unauthorized users are not able to access the routes, however I don’t get laravel_token in my cookies and therefore I can’t get access to that route if I’m not logged in.
• Use passport’s client credentials grant access. Works fine and the way I want it to work but doesn’t really make sense because if I hardcode the client_secret – anyone can access it and then use it to access protected routes. If I make a proxy-like solution, to call a controller method, which would issue a valid token and thus not exposing client_secret to front-end but then anyone could just call that route which issues the token and it would be pointless once again.

You cannot stop people from trying to access of publicly visible API. You need to secure the API and only respond to those with the proper access privileges.

429 too many requests laravel 8

I stumbled upon the same problem today and did some debugging. When registering the /login route, Fortify applies the Illuminate\Routing\Middleware\ThrottleRequests:login middleware to it. This means, for every request to that route, the ThrottleRequests middleware will call the RateLimiter instance for that specified key. Apparently, Fortify doesn’t register a RateLimiter for the login key.

Due to the missing key in the $limiters property of the RateLimiter instance, the ThrottleRequests middleware uses its default fallback, which doesn’t handle the edge case “there SHOULD be a rate limiter for that key, but there isn’t.” really well. The $maxAttempts variable is set to 0 and will result in flaky rate limiting behaviour.

I feel like this is a bug in Fortify, because rate limiting is also happening in the \Laravel\Fortify\Actions\EnsureLoginIsNotThrottled action, which is invoked in the \Laravel\Fortify\Http\Controllers\AuthenticatedSessionController controller. I didn’t check this on a fresh Laravel installation, though, so I don’t want to jump to conclusions here.

Anyway, long story short: As a workaround, you can simply register a rate limiter for the “login” key in some of your providers, e. g. AppServiceProvider or AuthServiceProvider:

public function boot()
{
    RateLimiter::for("login", function () {
        Limit::perMinute(5);
    });
}

Edit: I just realized that the rate limiter for the “login” key is indeed provided by Fortify within the FortifyServiceProvider class. If you happen to have a problem similar to the one discussed above, make sure that you added the FortifyServiceProvider class to your providers array in the config/app.php.
