The Google ReCaptcha is an open service that assures a computer user is a human. Google ReCaptcha is one of the most popular captcha systems that defends your site from bots spam and abuse. In order to integrate the reCaptcha, you must sign up for the Google API key & secret for your laravel application.

Step 1: Download Laravel

Let us begin the tutorial by installing a new laravel application. if you have already created the project, then skip following step.

composer create-project laravel/laravel example-app
Step 2: Install josiasmontag/laravel-recaptchav3 Package

In this step we need to install josiasmontag/laravel-recaptchav3 via the Composer package manager, so one your terminal and fire bellow command:

composer require josiasmontag/laravel-recaptchav3

After successfully install package, we require to publish config file with bellow command:

php artisan vendor:publish --provider="Lunaweb\RecaptchaV3\Providers\RecaptchaV3ServiceProvider"
Step 3: Update Google API Key

In this step we need to set google site key and secret key. If you don't have site key and secret key then you can create from here. First click on this link : Recaptcha Admin

Now you have to create new key for google recaptchav3 as bellow screen shot:

.env
RECAPTCHAV3_SITEKEY=[site-key]
RECAPTCHAV3_SECRET=[secret-key]
Step 4: Create RegisterController

In this step, we have to create new controller as RegisterController and we have also need to add two methods index() and store() on that controller like as you can see bellow:

app/Http/Controllers/RegisterController.php
<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
  
class RegisterController extends Controller
{
     /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function index()
    {
        return view('register');
    }
    
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function store(Request $request)
    {
        $this->validate($request, [
            'name' => 'required',
            'email' => 'required|email',
            'password' => 'required|same:password_confirmation',
            'password_confirmation' => 'required',
            'g-recaptcha-response' => 'required|recaptchav3:register,0.5'
        ]);
   
        dd('done');
    }
}
Step 5: Create Route

We need to create register routes as bellow:

routes/web.php
<?php
    
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\RegisterController;
    
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
   
Route::controller(RegisterController::class)->group(function(){
    Route::get('register', 'index');
    Route::post('register', 'store');
});
Step 6: Create View File

In Last step, let's create register.blade.php(resources/views/register.blade.php) for layout and lists all items code here and put following code:

resources/views/register.blade.php
