Once here, you’ll see the available spam protection options. Sugar Calendar Bookings currently supports Google reCAPTCHA and Cloudflare Turnstile protection. Below we’ll highlight the available options:

Google reCAPTCHA

reCAPTCHA is a free anti-spam service offered by Google. It adds an extra layer of security to online forms such as contact, newsletter, and booking forms. Protecting your form from spam and cyber attacks, while letting real users complete the form.

Select Google reCAPTCHA

You can choose between the Checkbox reCAPTCHA v2, Invisible reCAPTCHA v2, or reCAPTCHA v3 options.

For more details, see our tutorial on setting up Google reCAPTCHA for Sugar Calendar Bookings.

When filling out a booking form on your site’s frontend, you’ll see a Google reCAPTCHA badge at the bottom left of the page, indicating that the form is protected.

It is offered by Cloudflare and provides a user-friendly experience by validating visitors without requiring them to solve puzzles or math questions.
