How to bypass Geetest v4 CAPTCHA

Published:

Recenly Geetest launched new version of their CAPTCHA: v4. The captcha challenge is quite similar to the previous version, you still need to move a slider to solve a puzzle.
You can check how does it look on our demo page.

We've added a new method to our API that will allow you bypass the CAPTCHA challenge automatically.

Collect the captcha parameters

To successfully bypass the captcha you need to grab just two values:

  • captcha_id (please don't confuse it with the id if your captcha in our system) - the unique ID of the captcha attached to a website/page
  • pageurl - the URL of the page where you bypass the captcha

The captcha_id value can be found on the HTML source of the page inside the <script> tag that includes the Geetest javascript code on the page.

Interact with our API

When you have all required values submit the captcha to in.php endpoint of our API with the following parameters:

parameterdescription
methodgeetest_v4 - indicates that you need to solve Geetest v4
captcha_idthe value of captcha_id you found on the page
pageurlfull URL of page where you need to solve the CAPTCHA

Then use the returned id of your captcha to make request to res.php API endpoint. Once the captcha is solved you will receive the answer in JSON format:

{
    "captcha_id": "e392e1d7fd421dc63325744d5a2b9c73",
    "lot_number": "7fafac97a43d4701aee908afa49c73ba",
    "pass_token": "6f1c27bd15777d5e9e6e1ba94604c28e7b13b94eed3f7c8b79ceaf4660da6320",
    "gen_time": "1648112802",
    "captcha_output": "FEB0Fyp2UEcHdeFQ0PEN-BHenkuCzlpmfX_OLXuf49iF_rPvbjYc9whxQg-sYOCPSzX_19HF0gCPgSoAZ-JPxE46ddE7L6y0J-D_5CcMnT0IYKHFK-NdcBo_m6nISKrpSH3QE9l5r53UTChJdR-bOJPO20gA0bgPEMvDCew7UkQ="
}

Use the returned values to construct the request to your target website. The best way to do that is to look how the data is sent when you bypass the captcha manually and then to do the same replacing the request content with the data received from our API.

The detailed API description is available in our API docs.
