It means your site key is not valid. Check your site key again or
Let me show your code block and the captcha url if you need more help.

I've tried it but I can't verify that my site key is correct. If you can help me, this is my code without my client key.

Just pass the site key manually. Right click to recaptcha box & inspect it. Then find data-sitekey attribute and copy the value.

Before all, your code doesn't compatible with mine. If you really need this, you have to learn more about using Selenium & bypassing/submitting recaptchas.

You can get from here

You can get from here

thank you. I got this error:

WebDriverException: Message: Service selenium/chromedriver.exe unexpectedly exited. Status code was: 1

Finally I figured it out by using executable_path = "geckodriver.exe". But I got blank page.

Hello, I getting this error:
capmonster_python.utils.CapmonsterException: [ERROR_KEY_DOES_NOT_EXIST] Account authorization key not found in the system or has incorrect format

Is the arg website_url the website itself or google recaptcha url?

URL = https://pocketoption.com/en/login/

<iframe title="reCAPTCHA" src="https://www.google.com/recaptcha/api2/anchor?ar=1&k=6LcU2hgUAAAAAPHmrOrfTDy6DnROjq7Mr8LNwhNF&co=aHR0cHM6Ly9wb2NrZXRvcHRpb24uY29tOjQ0Mw..&hl=pt&type=image&v=5qcenVbrhOy8zihcc2aHOWD4&theme=light&size=normal&cb=a5bmkkozyfou" width="304" height="78" role="presentation" name="a-fxy4vff1wo4t" frameborder="0" scrolling="no" sandbox="allow-forms allow-popups allow-same-origin allow-scripts allow-top-navigation allow-modals allow-popups-to-escape-sandbox"></iframe>

Hello @vinifr,

The ERROR_KEY_DOES_NOT_EXIST is means you doesn't have a valid api-key. Did you registered the capmonster.cloud?

And the website_url arg must be https://pocketoption.com/en/login/ in your case. Website URL means where is located the captcha.

ok. Do I have to click in recaptcha checkbox in order to solve it?

driver.find_element(By.CSS_SELECTOR,"iframe[title='reCAPTCHA']").click()

No you don't.

Just import your token to g-recaptcha-response

One more question. "driver.find_element(By.ID, "recaptcha-demo-submit").click()"

This is the "Verify" button in recaptcha iframe or the Sign in button ?

You don't have to click recaptcha checkbox. As mentioned in name, it's recaptcha's submit button.

Hello, @alperensert
Currently I can get g-captcha-response and I can write down in text-area.
How can I submit the captcha? In my project, there is no submit button like your's.(self.chrome.find_element(By.ID, "recaptcha-checkbox-checkmark").click())
What is next step?

(click vip experience, increase amount and checkout, if you can meet recaptcha in the site)
waiting your kindly reply
