Migrating from hCaptcha
If you are using hCaptcha today, you can switch seamlessly to Cloudflare Turnstile by following the step-by-step guide below to assist with the upgrade process.
To complete the migration, you must obtain the sitekey and secret key.
- Update the client-side integration by inserting the Turnstile script snippet in your HTML’s
<head>
element:
<script src="https://challenges.cloudflare.com/turnstile/v0/api.js" async defer></script>
- Locate the
hcaptcha.render()
calls and replace the sitekey with your Turnstile sitekey and the API.
// beforehcaptcha.render(element, { sitekey: "00000000-0000-0000-0000-000000000000"})// afterturnstile.render(element, { sitekey: "1x00000000000000000000AA"})
- Update the server-side integration by replacing the siteverify URL. Replace:
https://hcaptcha.com/siteverify
With:
https://challenges.cloudflare.com/turnstile/v0/siteverify
- Replace the
h-captcha-response
input name withcf-turnstile-response
.
