Solving reCaptcha V2 with CapSolver API

If you're struggling with reCaptcha v2 and need a way to solve it, this guide is for you. We'll use the CapSolver API to solve reCaptcha v2 easily. You can either use your own proxies with ReCaptchaV2Task or use the server's built-in proxy with ReCaptchaV2TaskProxyLess.

Creating a Task

To solve reCaptcha v2, you first need to create a task using the createTask method.

Here's the structure of the task object:

  • type: Required. This should be ReCaptchaV2Task or ReCaptchaV2TaskProxyLess.
  • websiteURL: Required. This is the web address of the website using reCaptcha v2.
  • websiteKey: Required. This is the domain's public key.
  • proxy: Optional. If you're using a proxy, you can include it here.
  • isInvisible: Optional. If the reCaptcha doesn't have pageAction, set this to true.
  • userAgent: Optional. If you're emulating a browser, include its User-Agent here.
  • cookies: Optional. If you need to use cookies, include them here.

Here's an example request:

{
  "clientKey": "YOUR_API_KEY",
  "task": {
    "type": "ReCaptchaV2Task",
    "websiteURL": "site",
    "websiteKey": "site key",
    "isInvisible": false,
    "userAgent": "",
    "cookies": [
      {
        "name": "__Secure-3PSID",
        "value": "sdadasdasdsda"
      },
      {
        "name": "__Secure-3PAPISID",
        "value": "sd/AytXQTb6RUALqxSEL"
      }
    ],
    "proxy": ""
  }
}

Once the task is successfully submitted, you'll receive a Task ID in the response:

{
    "errorId": 0,
    "errorCode": "",
    "errorDescription": "",
    "taskId": "61138bb6-19fb-11ec-a9c8-0242ac110006"
}

Getting Results

Once you have the Task ID, you can use it to retrieve the solution. Submit the Task ID with the getTaskResult method. The results should be ready within an interval of 1s to 10s.

Here's an example request:

{
    "clientKey": "YOUR_API_KEY",
    "taskId": "61138bb6-19fb-11ec-a9c8-0242ac110006"
}

The response will include the solution token:

{
    "errorId": 0,
    "errorCode": null,
    "errorDescription": null,
    "solution": {
        "userAgent": "xxx", 
        "expireTime": 1671615324290, 
        "gRecaptchaResponse": "3AHJ....." // This is the solution token
    },
    "status": "ready"
}

Solve reCaptcha v2 with Python:

# Install the CapSolver SDK
# pip install --upgrade capsolver

# Set the CapSolver API key
# export CAPSOLVER_API_KEY='YOUR_API_KEY'

import capsolver
# capsolver.api_key = 'YOUR_API_KEY'

# Solve a reCAPTCHA v2 challenge
solution = capsolver.solve({
    "type": "ReCaptchaV2TaskProxyLess",
    "websiteURL": "site url",
    "websiteKey": "site key",
})

Solve reCaptcha v2 with GO:

package main

import (
    "fmt"
    capsolver_go "github.com/capsolver/capsolver-go"
    "log"
)

func main() {
    // Install the CapSolver SDK
    // go get github.com/capsolver/capsolver-go

    // Set the CapSolver API key
    // export CAPSOLVER_API_KEY='YOUR_API_KEY'
    // or
    // capSolver := CapSolver{apiKey:"YOUR_API_KEY"}

    capSolver := capsolver_go.CapSolver{}
    solution, err := capSolver.Solve(map[string]any{
        "type": "ReCaptchaV2TaskProxyLess",
        "websiteURL": "https://www.google.com/recaptcha/api2/demo",
        "websiteKey": "6Le-wvkSAAAAAPBMRTvw0Q4Muexq9bi0DJwx_mJ-",
    })
    if err != nil {
        log.Fatal(err)
        return
    }
    fmt.Println(solution)
}

Please replace YOUR_API_KEY with your actual CapSolver API key, and replace the websiteURL and websiteKey with the actual website URL and website key for the reCAPTCHA challenge you are trying to solve
