GeeTest CAPTCHA bypass API service
With our serivce your can easily bypass both versions of Geetest: v3 and v4, but first you need to indetify which version is used by your target website.
There are few attributes that can be used for the identification:
- v3 uses
initGeetestinitialization function and v4 usesinitGeetest4 - v3 loads
gt.jsscript, but v4 loadsgt4.js
GeeTest v3
Find the following GeeTest captcha parameters on the target website (usually you can find them inside
initGeetestfunction):gt- public website key (static)
challenge- dynamic challenge key
api_server- API domain (optional)Important: you should get a new `challenge` value for each request to our API. Once captcha was loaded on the page the `challenge` value becomes invalid. You should inspect requests made to the website when page is loaded to identify a request that gets a new `challenge` value. Then you should make such request each time to get a valid `challenge` value.
Send these parameters to 2Captcha API. If captcha is already solved server will return the response in JSON. The response contains three values:
challenge,validateandseccode:{ "challenge": "1a2b3456cd67890e12345fab678901c2de", "validate": "09fe8d7c6ba54f32e1dcb0a9fedc8765", "seccode": "12fe3d4c56789ba01f2e345d6789c012|jordan" }Use the values received from our API to submit your request to the target website placing the values into corresponding request fields:
geetest_challenge geetest_validate geetest_seccodeClick on "Check" button to submit the form.
