How to solve reCaptcha using Selenium [Python] with Capsolver Extension

Solving reCaptcha Using Selenium and Capsolver Extension

In this blog, we'll guide you through the process of setting up Selenium with the Capsolver extension to solve reCaptcha v2. This method can also be applied to other types of captchas.

1. Installing Selenium and Required Components

First, you need to install Selenium and other necessary components. You can do this using pip:

pip install selenium

Make sure you have the appropriate drivers for the browser you intend to use (e.g., ChromeDriver for Google Chrome, GeckoDriver for Firefox).

2. Configuring the Capsolver Extension

Download the Capsolver extension from here. Unzip it into the ./CapSolver.Browser.Extension directory at the root of your project.

The extension offers various settings, including automatic captcha solving, proxy support, and more. These settings are located in ./assets/config.json. Here's an example of the configuration:

{
  "apiKey": "YourApiKey",
  "useCapsolver": true,
  "useProxy": false,
  "proxyType": "http",
  "hostOrIp": "",
  "port": "",
  "proxyLogin": "",
  "proxyPassword": "",
  "enabledForBlacklistControl": false,
  "blackUrlList": [],
  "enabledForRecaptcha": true,
  "enabledForRecaptchaV3": true,
  "enabledForHCaptcha": true,
  "enabledForFunCaptcha": true,
  "reCaptchaMode": "token",
  "hCaptchaMode": "click",
  "reCaptchaDelayTime": 0,
  "hCaptchaDelayTime": 0,
  "reCaptchaRepeatTimes": 10,
  "reCaptcha3RepeatTimes": 10,
  "hCaptchaRepeatTimes": 10,
  "funCaptchaRepeatTimes": 10
}

Insert your API key in the apiKey field in ./assets/config.json. You can find your API key on the Capsolver page.

For this example, we'll use the reCaptchaMode set to token, but you can also use click mode for reCaptcha.

3. Setting Up Selenium to Solve reCaptcha with Capsolver Extension

First, you need to set up Selenium WebDriver and configure it to use the Capsolver extension. Here's an example using ChromeDriver in Python:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import os

def main():
    extension_path = os.path.abspath('./CapSolver.Browser.Extension')
    chrome_options = Options()
    chrome_options.add_argument(f'--load-extension={extension_path}')

    driver = webdriver.Chrome(options=chrome_options)
    driver.get('https://www.google.com/recaptcha/api2/demo')

    # Wait for the captcha to be solved automatically by the extension
    WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.ID, 'recaptcha-demo-submit')))

    # Here, you can proceed with your form submission or any other actions post-captcha solving

    driver.quit()

if __name__ == "__main__":
    main()

Full Code:

The provided Python script is complete and ready to run. Ensure you've correctly set up your environment with the required packages and drivers, and don't forget to adjust the extension_path as necessary to point to your Capsolver extension directory.

And that's it! You have successfully solved reCaptcha v2 using the Capsolver Extension and Selenium in Python. To solve other types of captchas, simply follow the same steps and adjust accordingly.
