Hello everybody !

For this site : https://tr.foursquare.com/signup/ I've tried so many times to find callback function.

In google console i look under ___grecaptcha_cfg.clients[0] but i cant find callback function.

I'm using 2Captcha and there is no submit button.Site say it position must be smilar that "___grecaptcha_cfg.clients[0].aa.l.callback"

Please help me to find , thanks so much.

Now i solved it with the help of 2chaptca support.
If there is no callback function in path , it not necessarily to trigger a js callback function.
I just clicked web site sign up button after fill the forms and 2chaptca response.

My Question is where you find this?
___grecaptcha_cfg.clients[0].i_.O.callback.

If you Share step by step to find the callback. we will able to find all URL's callback and don't have to ask for every page.

To find and determine the callback function there are 2 ways:
1) easy (can be used for most of the sites): https://2captcha.com/2captcha-api#callback
2) hard (for tricky sites who are probably trying to hide it): https://captchaforum.com/threads/pr...allback-function-at-mail-com-sign-up-page.56/
