Google reCAPTCHA V3 demo: Sample Form with Google reCAPTCHA V3

In many cases reCAPTCHA V3 hinder accessibility, frustrate users, limits access to open information, makes testing application and sites difficult. Use reCAPTCHA V3 solver for automatic bypass.

reCAPTCHA V3 solver API

How to solve reCAPTCHA V3

Explore the source code of the website and search for grecaptcha.execute call. The call can be anywhere in the website code, inside <script> elements of the page of inside the included javascript files. For example, on our demo page source code you will find:

window.grecaptcha.ready(function() {
    grecaptcha.execute(
        '6LfB5_IbAAAAAMCtsjEHEHKqcB9iQocwwxTiihJu', 
        {action: 'demo_action'},
    ).then(function(token) {
        if (window.verifyRecaptcha) {
        window.verifyRecaptcha(token);
        }
    });
});

There you can find all the required values to solve the captcha with our API. And also you can see .then() method call - that's the code that handles the token after it was generated. You need to call the same code and pass the token received from our API.

Send sitekey, pageurl and action values to our API.

With SDK (recommended):

PHP

// https://github.com/2captcha/2captcha-php

require(__DIR__ . '/../src/autoloader.php');

$solver = new \TwoCaptcha\TwoCaptcha('YOUR_API_KEY');

try {
    $result = $solver->recaptcha([
        'sitekey' => '6LfB5_IbAAAAAMCtsjEHEHKqcB9iQocwwxTiihJu',
        'url'     => 'https://2captcha.com/demo/recaptcha-v3',
        'version' => 'v3',
        'action'  => 'demo_action',
        'score'   => 0.9,
    ]);
} catch (\Exception $e) {
    die($e->getMessage());
}

die('Captcha solved: ' . $result->code);

Python

# https://github.com/2captcha/2captcha-python

import sys

sys.path.append(os.path.dirname(os.path.dirname(os.path.realpath(__file__))))

from twocaptcha import TwoCaptcha

solver = TwoCaptcha(api_key)

try:
    result = solver.recaptcha(
        sitekey='6LfB5_IbAAAAAMCtsjEHEHKqcB9iQocwwxTiihJu',
        url='https://2captcha.com/demo/recaptcha-v3',
        version='v3',
        action='demo_action',
        score=0.9
    )

except Exception as e:
    sys.exit(e)

else:

Ruby

# https://github.com/2captcha/2captcha-ruby
require 'api_2captcha'

  pageurl: 'https://mysite.com/page/with/recaptcha_v3',
  version: 'v3',
  score: 0.3,
  action: 'verify'
})

Wait for the result, which may look like this:

Manually:

Send GET or POST request to our API URL: https://2captcha.com/in.php with method set to userrecaptcha, version set to v3 and provide the value found on previous step as value for googlekey and full page URL as value for pageurl.
Request example:
GET https://2captcha.com/in.php?key=YOUR_API_KEY&method=userrecaptcha&version=v3&min_score=0.9&action=demo_action&googlekey=6LfB5_IbAAAAAMCtsjEHEHKqcB9iQocwwxTiihJu&pageurl=http://2captcha.com/demo/recaptcha-v3
If everything is fine server will return the ID of your captcha:

OK|2122988149
Otherwise server will return an error code.
After 15-20 seconds send GET request to get the result:

GET https://2captcha.com/res.php?key=YOUR_API_KEY&action=get&id=2122988149
If captcha is already solved server will respond with the token:

OK|03AGdBq27lvCYmKkaqDdxWLfMe3ovADGfGlSyiR-fN_EJrZGniTAmdH1XSjK8ralsctfjOLX2K0T7dJfxPqqga8dtSG2Lmns8Gk2ckcU6PQzUFieBqrtpkr5PPwnngew0Rnot2ik1y8m202u6pHTIquExlEYSlzS8vfoyPPt8fCf-Zrbu8vWkiY8Ogj17ommHMgkguZbmEyOdfLTXzhRko-a655_jJdCMjEtMxva-b78DnGlXu9d0o6vEmrw9n8ABu4lLsWnIbYPH0beXRRIkUE3si64Xhwkh1aO3L1HaIR3sfR0vOs3GV1OBzry
If captcha is not solved yet server will return CAPCHA_NOT_READY result. Repeat your request in 5 seconds. If something went wrong server will return an error code.

Once we have a token we can execute the same code that is exexuted inside .then() method call and pass our token as the function call argument. In our demo case we can open javacsript execute the following code in the javascript console:
```
window.verifyRecaptcha('03AGdBq27lvCYmKkaqDdxWLfMe3ovADGfGlSyiR-fN_EJrZGniTAmdH1XSjK8ralsctfjOLX2K0T7dJfxPqqga8dtSG2Lmns8Gk2ckcU6PQzUFieBqrtpkr5PPwnngew0Rnot2ik1y8m202u6pHTIquExlEYSlzS8vfoyPPt8fCf-Zrbu8vWkiY8Ogj17ommHMgkguZbmEyOdfLTXzhRko-a655_jJdCMjEtMxva-b78DnGlXu9d0o6vEmrw9n8ABu4lLsWnIbYPH0beXRRIkUE3si64Xhwkh1aO3L1HaIR3sfR0vOs3GV1OBzry')
```

Please keep in mind that exact captcha implementation on a particular website depends on the website author. Our demo page shows just one, but very popular implemetation method.
