How to solve reCAPTCHA V2 Callback

  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>

  2. Send sitekey and pageurl to our API.

    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-callback',
    ]);
} catch (\Exception $e) {
    die($e->getMessage());
}

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

    Python

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

import sys
import os

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-callback')

except Exception as e:
    sys.exit(e)

else:
    sys.exit('solved: ' + str(result))

    Ruby

require 'api_2captcha'

client =  Api2Captcha.new("YOUR_API_KEY")

result = client.recaptcha_v2({

  pageurl: 'https://mysite.com/page/with/recaptcha_v2'
})

    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 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-callback

    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, execute the callback function verifyDemoRecaptcha passing the token string as an argument like: verifyDemoRecaptcha('TOKEN')
    Please note that each website has own reCAPTCHA implementation with unique callback definition and the callback function name will be different from our demo, or even an anonymous function can be used. This code snippet can help you to find the callback definition.
