Hi @nguilherme010, thanks for posting.
There is a similar post here on the Netlify Forums that shows you how to implement the reCaptcha validation.
Kindly visit the link below on how to configure the reCaptcha validation.

Know if reCaptcha v2 was checked or not

Hello, I have a very simple static site, using Netlify form feature with reCaptcha v2 : Test - Contact I am looking for a way to have a simple form validation, know if the captcha was checked and validated or not, simply to enable/disable submit button depending on this result. Is it any possible ? Maybe there is an event in JS telling that the captcha was checked ? Or should I go with my custom reCaptcha solution instead of using Netlify one ? Thank you

Hope this helps.
Let me know if the suggestions in the post helps.
Thanks.
