Cloudflare Turnstile

What is Turnstile?

Turnstile is Cloudflare's visitor challenge for forms. A widget on the page, or a check Formbold adds for you, runs a challenge and produces a token. The idea is to keep bots out without a puzzle.

Formbold supports Turnstile two ways, under Spam & Security in your form's Settings tab. In the dashboard the two options are labelled Automatic CAPTCHA and Custom CAPTCHA:

• Automatic Turnstile: nothing to add to your site. Formbold shows a short Almost there page after submit. All plans, including Free. See Automatic Turnstile.
• Custom Turnstile: you add a Turnstile widget to your form and save its secret key in Formbold. All plans, including Free. See Custom Turnstile.

Which should I use?

Use Custom Turnstile if your form has file inputs, or if it submits with fetch() or Ajax. Automatic Turnstile sends the visitor to that Almost there page after submit, and that extra step can drop uploaded files or break an Ajax request.

For a simple HTML form with no files, Automatic Turnstile is the quicker setup.
