How to solve reCaptcha v2

What is reCaptcha?

There are several versions of reCAPTCHA:

  • reCAPTCHA v1: The original version, which presented users with distorted text and asked them to type it into a box.
  • reCAPTCHA v2: This version asks users to click on a checkbox confirming that they are not a robot. Sometimes it can also ask users to select specific types of images from a grid.
  • reCAPTCHA v3: This version works in the background of websites to analyze user behavior and assign a score based on the perceived likelihood that the user is human or a bot. It's a more seamless experience for the user because it doesn't require any specific user interaction like previous versions.

In this blog, we will focus on solving reCAPTCHA v2 and looks like:

How to solve reCaptcha v2

To solve reCaptcha v2, follow our documentation. Some parameters are required and some are optional. For this example, we will only use the required parameters. The task types for reCAPTCHA v2 are:

  • ReCaptchaV2Task: This task type requires your own proxies.
  • ReCaptchaV2TaskProxyLess: This task type uses the server's built-in proxy.
  • ReCaptchaV2EnterpriseTask: This task type requires your own proxies.
  • ReCaptchaV2EnterpriseTaskProxyLess: This task type uses the server's built-in proxy.

For this example, we will use ReCaptchaV2TaskProxyLess as the site uses standard reCAPTCHA v2. If the site uses Recaptcha Enterprise, you will need to send the correct task type (ReCaptchaV2EnterpriseTaskProxyLess or ReCaptchaV2EnterpriseTask) and ensure all required parameters are included.
If any parameters are missing, you will likely encounter issues with the token not being accepted by the website. You can find all the parameters in this picture:

For get the captcha solved, first you need to submit all the information needed, for this we use the method createTask:

Step 1: Submitting the information to capsolver


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

Step 2: Getting the results

To verify the results, you'll need to continuously poll the getTaskResult API endpoint until the captcha is resolved.

Here's an example request:

Content-Type: application/json

    "taskId": "TASKID_OF_CREATETASK" //ID created by the createTask method

Once the captcha is successfully resolved, you'll receive a response similar to the one depicted in the following image:

The captcha token received can be verified by submitting it to the relevant site.

⚠️ If the token is rejected, it may indicate that some information is missing or incorrect. We recommend thoroughly checking whether the reCaptcha is standard or enterprise and whether it requires additional parameters listed as optional in our documentation.

In conclusion, while solving reCAPTCHA may seem a daunting task, makes the process swift and efficient. By following the steps outlined above, you can easily resolve reCAPTCHA v2.
