Incorporating Captcha for Button Click

I was wondering if there was a way to add a captcha to a web page that does not contain any form fields for the user to complete (eg. email). The captcha would only need to prevent the user from clicking on the button to continue to the next page. Perhaps the button is greyed until the captcha checks the user.

Would this work?

Hi @PeterS72., It is possible to add a captcha to a page without any form fields. You would need to use a service such as Google reCAPTCHA, which provides a simple API that can be integrated into your HTML page.
The API will generate a captcha challenge (such as selecting images or solving a math problem) which the user must complete before the button is enabled.
You can find more information and instructions on how to set up reCAPTCHA on your page here: reCAPTCHA v2  |  Google for Developers.
Hope this helps! Cheers:)
