reCAPTCHA V2 demo

How to solve reCAPTCHA V2

1. Open developer's console in your browser and find element with data-sitekey attribute.

   <div class="g-recaptcha" data-sitekey="6LfD3PIbAAAAAJs_eEHvoOl75_83eXSqpPSRFJ_u" id="recaptcha"></div>Skopiuj fragment kodu

2. Send sitekey and pageurl 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' => '6LfD3PIbAAAAAJs_eEHvoOl75_83eXSqpPSRFJ_u',
           'url'     => 'https://2captcha.com/demo/recaptcha-v2',
       ]);
   } catch (\Exception $e) {
       die($e->getMessage());
   }
   
   die('Captcha solved: ' . $result->code);Skopiuj fragment kodu

   Python

   sys.path.append(os.path.dirname(os.path.dirname(os.path.realpath(__file__))))
   
   from twocaptcha import TwoCaptcha
   
   api_key = os.getenv('APIKEY_2CAPTCHA', 'YOUR_API_KEY')
   
   solver = TwoCaptcha(api_key)
   
   try:
       result = solver.recaptcha(
           sitekey='6LfD3PIbAAAAAJs_eEHvoOl75_83eXSqpPSRFJ_u',
           url='https://2captcha.com/demo/recaptcha-v2')

   Manually:

   1. Send GET or POST request to our API URL: https://2captcha.com/in.php with method set to userrecaptcha 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&googlekey=6LfD3PIbAAAAAJs_eEHvoOl75_83eXSqpPSRFJ_u&pageurl=http://2captcha.com/demo/recaptcha-v2

   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 answer token:

      OK|03AHJ_Vuve5Asa4koK3KSMyUkCq0vUFCR5Im4CwB7PzO3dCxIo11i53epEraq-uBO5mVm2XRikL8iKOWr0aG50sCuej9bXx5qcviUGSm4iK4NC_Q88flavWhaTXSh0VxoihBwBjXxwXuJZ-WGN5Sy4dtUl2wbpMqAj8Zwup1vyCaQJWFvRjYGWJ_TQBKTXNB5CCOgncqLetmJ6B6Cos7qoQyaB8ZzBOTGf5KSP6e-K9niYs772f53Oof6aJeSUDNjiKG9gN3FTrdwKwdnAwEYX-F37sI_vLB1Zs8NQo0PObHYy0b0sf7WSLkzzcIgW9GR0FwcCCm1P8lB-50GQHPEBJUHNnhJyDzwRoRAkVzrf7UkV8wKCdTwrrWqiYDgbrzURfHc2ESsp020MicJTasSiXmNRgryt-gf50q5BMkiRH7osm4DoUgsjc_XyQiEmQmxl5sqZP7aKsaE-EM00x59XsPzD3m3YI6SRCFRUevSyumBd7KmXE8VuzIO9lgnnbka4-eZynZa6vbB9cO3QjLH0xSG3-egcplD1uLGh79wC34RF49Ui3eHwua4S9XHpH6YBe7gXzz6_mv-o-fxrOuphwfrtwvvi2FGfpTexWvxhqWICMFTTjFBCEGEgj7_IFWEKirXW2RTZCVF0Gid7EtIsoEeZkPbrcUISGmgtiJkJ_KojuKwImF0G0CsTlxYTOU2sPsd5o1JDt65wGniQR2IZufnPbbK76Yh_KI2DY4cUxMfcb2fAXcFMc9dcpHg6f9wBXhUtFYTu6pi5LhhGuhpkiGcv6vWYNxMrpWJW_pV7q8mPilwkAP-zw5MJxkgijl2wDMpM-UUQ_k37FVtf-ndbQAIPG7S469doZMmb5IZYgvcB4ojqCW3Vz6Q
      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. In developer's console, find textarea with id="g-recaptcha-response", and put there received code. Then, click the Check button.
