How to identify the 32 bit data-sitekey of ReCaptcha V2 to obtain a valid response programmatically using Selenium and Python Requests?

Question

Pretty much new with captcha and Python requests. The captcha documentation says to copy the value of data-sitekey parameter.

Here was my attempt, using

Answer 1

data-sitekey represented through 41-characters string works just fine. The error ERROR_WRONG_USER_KEY occurred as I never had a valid API key ready in the first place. Even with Zero balance in your account, you can successfully obtain a <Response [200]> with text as ERROR_ZERO_BALANCE as follows:

• Code Block:

  from selenium import webdriver
  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC
  import requests
  
  options = webdriver.ChromeOptions() 
  options.add_argument("start-maximized")
  options.add_experimental_option("excludeSwitches", ["enable-automation"])
  options.add_experimental_option('useAutomationExtension', False)
  driver = webdriver.Chrome(options=options, executable_path=r'C:\WebDrivers\chromedriver.exe')
  mainurl = 'https://imagetyperz.xyz/automation/recaptcha-v2.html'
  driver.get(mainurl)
  data_sitekey = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CLASS_NAME, "g-recaptcha"))).get_attribute("data-sitekey")
  print(data_sitekey)
  api_key = '--------------------------------'
  data_post = {'key': api_key, 'method': 'userrecaptcha', 'googlekey': data_sitekey, "pageurl": mainurl}
  response = requests.post(url = 'https://2captcha.com/in.php', data = data_post )
  print(response)
  print(response.text)
