How to Bypass Google reCAPTCHA

What is Google reCAPTCHA

Google reCAPTCHA is a service designed to protect websites from spam and abuse by distinguishing between human users and automated bots. It works by presenting challenges that are easy for humans to solve but difficult for bots. The system helps prevent malicious activities like web scraping, brute force attacks, and spam submissions on forms.
Google reCAPTCHA uses machine learning and risk analysis techniques to improve its accuracy over time, helping to prevent more sophisticated types of bots and automated abuse.

Types of Google reCAPTCHA

There are several versions of Google reCAPTCHA, including:

  1. reCAPTCHA v2: This is the most commonly used version, which presents a checkbox ("I am not a robot") that users must click. In some cases, it might also present an image recognition challenge (e.g., selecting all images with cars or traffic lights) to verify if the user is human.
  2. reCAPTCHA v3: Instead of requiring direct user interaction, reCAPTCHA v3 runs in the background and assigns a score (from 0 to 1) based on the user's behavior on the site. This score helps the website determine the likelihood that the user is a bot.
  3. Invisible reCAPTCHA: This version operates similarly to reCAPTCHA v2 but without requiring the user to explicitly interact with a checkbox. It appears only when necessary, such as when the system suspects the user may be a bot.
  4. Enterprise reCAPTCHA: This is a premium version of Google’s reCAPTCHA service designed for businesses and organizations that need additional features, customization, and support to secure their websites and applications. It provides enhanced security, more control over the user experience, and better integration with enterprise-level systems.

How to Automatically Solve Google reCAPTCHA with API v2

1. Using the 2Captcha API

2Captcha provides a way to automatically solve Google reCAPTCHA using API v2.

General process:

  1. Find the site key (sitekey) on the target page.
  2. Send it to the 2Captcha API v2.
  3. Get the solution token.
  4. Insert the token into the form and submit it.

Example request for solving reCAPTCHA v2

Submitting a task:

curl -X POST "https://api.2captcha.com/createTask" \
     -H "Content-Type: application/json" \
     -d '{
           "clientKey": "YOUR_API_KEY",
           "task": {
               "type": "RecaptchaV2TaskProxyless",
               "websiteURL": "https://example.com",
               "websiteKey": "SITE_KEY"
           }
         }'

Response (Task ID):

{
  "errorId": 0,
  "taskId": 123456789
}

Requesting the solution:

curl -X POST "https://api.2captcha.com/getTaskResult" \
     -H "Content-Type: application/json" \
     -d '{
           "clientKey": "YOUR_API_KEY",
           "taskId": 123456789
         }'

Response with solution:

{
  "errorId": 0,
  "status": "ready",
  "solution": {
      "gRecaptchaResponse": "03AGdBq25fN2f..."
  }
}

The token (gRecaptchaResponse) needs to be inserted into the hidden form field and submitted.

2. Using Python to Solve reCAPTCHA v2 via API v2

If you are using Python, here is an example of solving reCAPTCHA v2 using 2Captcha API v2:

import time
import requests

API_KEY = "YOUR_API_KEY"
SITE_KEY = "SITE_KEY"
PAGE_URL = "https://example.com"

# 1. Submitting a task to the 2Captcha API v2
create_task_url = "https://api.2captcha.com/createTask"
task_payload = {
    "clientKey": API_KEY,
    "task": {
        "type": "RecaptchaV2TaskProxyless",
        "websiteURL": PAGE_URL,
        "websiteKey": SITE_KEY
    }
}
task_response = requests.post(create_task_url, json=task_payload).json()

if task_response["errorId"] != 0:
    raise Exception("Error submitting task:", task_response)

task_id = task_response["taskId"]
print("Task ID:", task_id)

# 2. Waiting for the solution
time.sleep(20)  # Allow 2Captcha some time to process the request

get_result_url = "https://api.2captcha.com/getTaskResult"
for _ in range(10):  # Try 10 times at 5-second intervals
    result_payload = {"clientKey": API_KEY, "taskId": task_id}
    result_response = requests.post(get_result_url, json=result_payload).json()
    
    if result_response["status"] == "ready":
        captcha_solution = result_response["solution"]["gRecaptchaResponse"]
        print("Solution:", captcha_solution)
        break
    
    print("Waiting...")
    time.sleep(5)

The token obtained in captcha_solution needs to be inserted into the g-recaptcha-response field and submitted with the form.

3. Using API v2 to Solve reCAPTCHA v3

For reCAPTCHA v3, you need to use the RecaptchaV3TaskProxyless task type, which requires specifying an action and minimum score.

Request to solve reCAPTCHA v3:

curl -X POST "https://api.2captcha.com/createTask" \
     -H "Content-Type: application/json" \
     -d '{
           "clientKey": "YOUR_API_KEY",
           "task": {
               "type": "RecaptchaV3TaskProxyless",
               "websiteURL": "https://example.com",
               "websiteKey": "SITE_KEY",
               "minScore": 0.3,
               "pageAction": "login"
           }
         }'

Response (Task ID):

{
  "errorId": 0,
  "taskId": 987654321
}

Requesting the solution:

curl -X POST "https://api.2captcha.com/getTaskResult" \
     -H "Content-Type: application/json" \
     -d '{
           "clientKey": "YOUR_API_KEY",
           "taskId": 987654321
         }'

Response with solution:

{
  "errorId": 0,
  "status": "ready",
  "solution": {
      "gRecaptchaResponse": "03AGdBq25fN2f..."
  }
}

The gRecaptchaResponse token needs to be inserted into the form, just like with reCAPTCHA v2.
