I can’t deal with reCAPTCHA - why do different values ​​​​receive all the time on the server, if the point is to just have a check mark (true value)?

Question

reCAPTCHA

Hello. I installed reCAPTCHA on my website. And when I check the box (I pass the check), different values ​​come to the server in $_POST['g-recaptcha-response'] .
In the first case, this is what happened:

In the second one is:

Why is that? In fact, the main thing is that the checkbox is true (and the value should come true)? Or am I wrong?

Answer 1

The result obtained from $_POST['g-recaptcha-response'] must be sent to them on the server and get the result of checking the recaptcha, whether it is a bot or not
