How to Solve Google reCAPTCHA

Understanding reCAPTCHA

There exist multiple versions of reCAPTCHA:

  • reCAPTCHA v1: The pioneer version that would present users with garbled text to be entered in a text box.
  • reCAPTCHA v2: This variant prompts users to tick a checkbox to affirm that they are not a bot. At times, it may also ask users to select certain categories of images from a grid.
  • reCAPTCHA v3: Operating discreetly in the background of websites, this version analyses user behavior and assigns a score based on the calculated probability of the user being a human or a bot. It provides a more streamlined experience for the user as it doesn't necessitate any specific interaction like its predecessors.

In this article, we will concentrate on deciphering reCAPTCHA v2.

Decoding reCAPTCHA v2

To decipher reCAPTCHA v2, you need to adhere to our guidelines. Certain parameters are mandatory while others are optional. For the purpose of this demonstration, we will focus on the compulsory parameters. The task classifications for reCAPTCHA v2 are:

  • ReCaptchaV2Task: This task category necessitates your own proxies.
  • ReCaptchaV2TaskProxyLess: This task category employs the server's internal proxy.
  • ReCaptchaV2EnterpriseTask: This task category necessitates your own proxies.
  • ReCaptchaV2EnterpriseTaskProxyLess: This task category employs the server's internal proxy.

For our demonstration, we will be utilizing ReCaptchaV2TaskProxyLess as the website employs the standard reCAPTCHA v2. If the website implements Recaptcha Enterprise, you will need to dispatch the appropriate task type (ReCaptchaV2EnterpriseTaskProxyLess or ReCaptchaV2EnterpriseTask) and ensure all necessary parameters are included.

In the event of any missing parameters, chances are high that the token may not be accepted by the website. You can locate all the parameters in the provided image.

To solve the captcha, the initial step is to submit all the requisite information, for this, we use the method createTask.

Step 1: Feeding the Information into Capsolver


  "clientKey": "YOUR_API_KEY",
  "task": {
    "type": "ReCaptchaV2TaskProxyless",
    "websiteURL": "site",
    "websiteKey": "site key"

Step 2: Retrieving the Results

To authenticate the results, you'll need to consistently ping the getTaskResult API endpoint until the captcha gets solved.

Here's a sample request:

Content-Type: application/json

    "taskId": "TASKID_OF_CREATETASK```markdown

Upon successful resolution of the captcha, you'll receive a response akin to the one shown in the accompanying image. The captcha token received can be authenticated by submitting it to the concerned site.

⚠️ If the token gets rejected, it might imply that some information is either missing or incorrect. We advise conducting a comprehensive check to ascertain whether the reCAPTCHA is standard or enterprise and whether it necessitates any additional parameters classified as optional in our guidelines.
