You can do this. Here’s how you can implement this.
Sign up to Google and get the keys for Recaptcha V2. Select Invisible while you do this on Google’s backend.
Add keys to the Webflow and enable it from project settings.
After that, add the recaptcha element to the form and give custom attribute to recaptcha element “data-size: invisible”
And that’s it. The invisible captcha will start working.
I hope this helps.
