Hi,
I am currently working on a program that allows to detect reCaptchas on a website and then send them to a Computer where a human will solve them.
The problem is that I do not really know how to let the program detect if a Captcha appeared or not.
My idea was to analyse the website through it's javascript and check if a certain element appeared.
I tried locating the captcha window through the xPath that's referncing to it. This did not work.
I also tried to get the id of the button of the captcha that sais "confirm" and check if it was present on the page.
If it was present it would mean that the captcha had appeared and if it was not it would mean that there is no Captcha.
This did not work either because my program was not able to find the button by it's id. It seems to my like google has found a way to kind of "mask" the captcha.
Is there any way for me to detect it ?
Can anyone help me ?
Thanks!

Just analyse the source page when captcha appears and when it doesnt. Look for differences and note what changes

Can you give me more details on what i should analyse ? Because i was not able to find any pattern of things that change between the moment where there is no captcha and the moment where there is one
