Modifying an existing reCAPTCHA\nintegration involves instrumenting the web pages and migrating the backend calls.\n\nBefore you begin\n----------------\n\n[Migrate to reCAPTCHA](/recaptcha/docs/migrate-recaptcha).\n\nInstrument the web pages\n------------------------\n\nTo instrument the web pages with the reCAPTCHA scripts and\ncalls, do the following:\n\n1. Verify that you have the following script included in your web pages: `https://www.google.com/recaptcha/api.js`.\n2. In your web pages, replace `https://www.google.com/recaptcha/api.js`\n with `https://www.google.com/recaptcha/enterprise.js`.\n\n | **Note:** If your web pages have the `https://www.recaptcha.net/recaptcha/api.js` script, then replace it with `https://www.recaptcha.net/recaptcha/enterprise.js`.\n3. If you programmatically invoke the API, then replace the following calls:\n\n - `grecaptcha.execute()` -\\\u003e `grecaptcha.enterprise.execute()`\n - `grecaptcha.getResponse()` -\\\u003e `grecaptcha.enterprise.getResponse()`\n - `grecaptcha.ready()` -\\\u003e `grecaptcha.enterprise.ready()`\n - `grecaptcha.render()` -\\\u003e `grecaptcha.enterprise.render()`\n - `grecaptcha.reset()` -\\\u003e `grecaptcha.enterprise.reset()`\n\nMigrate the backend calls\n-------------------------\n\nTo use reCAPTCHA features, you must migrate your backend calls to\nthe new endpoints and set up authentication:\n\n1. Replace backend calls to `https://www.google.com/recaptcha/api/siteverify`\n with equivalent calls to `recaptchaenterprise.googleapis.com`. For the complete\n URL and the POST data format, see [Create an assessment for your website](/recaptcha/docs/create-assessment-website).\n\n2.\n\n Set up authentication to reCAPTCHA.\n\n The authentication method you choose depends on the environment where\n reCAPTCHA is set up. The following table helps you choose the\n appropriate authentication method and the supported interface to set up\n authentication:\n\n \u003cbr /\u003e\n\nWhat's next\n-----------\n\n- [Create an assessment for your website](/recaptcha/docs/create-assessment-website)"]]
