[Skip to content](#%5Ftop) ### Tags [ Migration ](https://developers.cloudflare.com/search/?tags=Migration) # Migrate 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](https://developers.cloudflare.com/turnstile/get-started/widget-management/). ## Client-side integration 1. Update the client-side integration by inserting the Turnstile script snippet in your HTML's `` element: Turnstile script snippet ``` ``` 2. Locate the `hcaptcha.render()` calls and replace the sitekey with your Turnstile sitekey and the API. Render ``` // before hcaptcha.render(element, { sitekey: "00000000-0000-0000-0000-000000000000" }) // after turnstile.render(element, { sitekey: "1x00000000000000000000AA" }) ``` Note Turnstile supports: * the `render()` call * hCaptcha invisible mode with the `execute()` call ## Server-side integration 1. Update the server-side integration by replacing the Siteverify URL. Replace: `https://hcaptcha.com/siteverify` with the following: ``` https://challenges.cloudflare.com/turnstile/v0/siteverify ``` 2. Replace the `h-captcha-response` input name with the following: ``` cf-turnstile-response ``` ```json {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/directory/","name":"Directory"}},{"@type":"ListItem","position":2,"item":{"@id":"/turnstile/","name":"Turnstile"}},{"@type":"ListItem","position":3,"item":{"@id":"/turnstile/migration/","name":"Migration"}},{"@type":"ListItem","position":4,"item":{"@id":"/turnstile/migration/hcaptcha/","name":"Migrate from hCaptcha"}}]} ```
