Site Key	read-only display	NA	The public site key for the configured CAPTCHA provider, populated automatically from site settings.

note

CAPTCHA configuration (provider type, site key, secret key) is managed in Admin Console → Security settings, not in the flow canvas. The Captcha node reads those settings automatically.

Usage Notes

Drop the Captcha node inside any Web Page node where you want to challenge the user with CAPTCHA. The node automatically uses the CAPTCHA provider and keys configured in your site's Admin Console security settings: no manual key entry is required in the flow. CAPTCHA validation happens before the Web Page output fires.
