How to solve invisible captcha on Selenium

Question

Hi I am trying to write a sign-up bot for UEFA.com using Selenium as requests I find to be too difficult for me to try so I am just working on automating the sign-up process even if it is a lot slower.

I am able to get to the final stage where I click on Create an Account, but faced with a reCaptcha which only appears after clicking on Create an Account. And after solving the captcha there is no 'Submit' button but it will automatically submit the details for you.

I am able to get the captcha token returned from 2captcha solving service, and inputted it into the innerHTML of the g-response-token field using javascript. However I do not know how to submit the captcha and the form.

    for name in e:
        name = name.strip()
        lastnames.append(name)

with open('proxies.txt') as f:
    proxy = f.readlines()

proxy_rand = randint(1, 35)
s_proxy = str(proxy[proxy_rand])

    except Exception as e:
        print(e)

    else:
        return result


result = SolveCaptcha()
code = result['code']
print(code)

token = f'document.getElementById("g-recaptcha-response").innerHTML="{code}";'
driver.execute_script(token)

time.sleep(10000)

As you can see by the end of the code I have managed to input the captcha token but not sure how to submit as there is no submit button

I have tried to look for a callback function but can't seem to find it when I inspect the page.

Answer 1

submit the first form on the page:

driver.execute_script('document.forms[0].submit()')

Answer 2

I just solve the problem like you. In this problem, it's really important to find a callback function. When you find it correctly and run it, the captcha will be solved.

for example, I run a callback function in my case. my website URL is link

driver.execute_script("grecaptcha.execute();")

I wish you also solve your problem
