You’re going to need a free Cloudflare account to use Captcha in Rock. Luckily the signup process only involves providing an email and creating a password. Once you’re logged in and looking at your dashboard, select Turnstile along the left. You’ll need to click the “Add widget” button to get started, then fill out the short form pictured below. At the end of the process, you’ll see a Site Key and a Secret Key. Keep these handy because they’ll both need to be copied into Rock. Back in Rock, navigate to Admin Tools > Settings > System Configuration Under the UI Settings panel, paste the two Keys. And that’s it! With your keys in place, the Workflow Entry and Transaction Entry v2 blocks will automatically perform a Captcha validation when they’re visited.
