Google Recaptcha v3 example demo

Question

Until now, I was working with Google Recaptcha v2, but now I want to update my WebApp using the lastest version (v3).

Is it possible to anyone add a fully working Go

Answer 1

We use recaptcha-V3 only to see site traffic quality, and used it as non blocking. Since recaptcha-V3 doesn't require to show on site and can be used as hidden but you have to show recaptcha privacy etc links (as recommended)

Script Tag in Head

HTML/Css Code:

there is no html code since our requirement is just to get score and don't want to show recaptcha badge.

Backend - Laravel Code:

Route:

Route::post('/recaptcha/score', 'Api\\ReCaptcha\\RecaptchaScore@index');


Class:

class RecaptchaScore extends Controller
{
    public function index(Request $request)
    {
        $score = null;

        $response = (new Client())->request('post', 'https://www.google.com/recaptcha/api/siteverify', [
            'form_params' => [
                'response' => $request->get('token'),
                'secret' => 'SECRET HERE',
            ],
        ]);

        $score = json_decode($response->getBody()->getContents(), true);

        if (!$score['success']) {
            Log::warning('Google ReCaptcha Score', [
                'class' => __CLASS__,
                'message' => json_encode($score['error-codes']),
            ]);
        }

        return [
            'response' => $score,
        ];
    }
} 

we get back score and save in variable which we later user when submit form.
