reCAPTCHA V3 Enterprise demo

How to solve reCAPTCHA V3 Enterprise

1. Explore the source code of the website and search for grecaptcha.enterprise.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.enterprise.ready(function() {
       window.grecaptcha.enterprise.execute(
           '6Lel38UnAAAAAMRwKj9qLH2Ws4Tf2uTDQCyfgR6b', 
           {action: 'demo_action'},
       ).then(function(token) {
           if (window.verifyRecaptcha) {
           window.verifyRecaptcha(token);
           }
       });
   });Copy code snippet

   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.

2. 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' => '6Lel38UnAAAAAMRwKj9qLH2Ws4Tf2uTDQCyfgR6b',
           'url'     => 'https://2captcha.com/demo/recaptcha-v3-enterprise',
           'version' => 'v3',
           'action'  => 'demo_action',
           'score'   => 0.9,
           'enterprise' => 1,
       ]);
   } catch (\Exception $e) {
       die($e->getMessage());
   }
   
   die('Captcha solved: ' . $result->code);Copy code snippet

   Wait for the result, which may look like this:

   Manually:

   1. 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=6Lel38UnAAAAAMRwKj9qLH2Ws4Tf2uTDQCyfgR6b&pageurl=http://2captcha.com/demo/recaptcha-v3-enterprise&enterprise=1

   2. If everything is fine server will return the ID of your captcha:

      OK|2122988149
      Otherwise server will return an error code.

   3. 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.

3. 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')Copy code snippet

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.
