## Permissions information

Functions in the Resources API are restricted and only run if you elevate permissions using the `wix-auth` [`elevate()`](https://www.wix.com/velo/reference/wix-auth/elevate) function.

<blockquote class='warning'>
<p><strong>Warning:</strong> Elevating a function allows it to be called by any site visitor. Exercise caution to prevent security vulnerabilities.</p>
</blockquote>

The reCAPTCHA element allows you to present a challenge-response test to site visitors to determine whether they are human or a bot. Use the reCAPTCHA element to verify that site visitors are human before allowing them perform restricted operations.

For more information on working with your reCAPTCHA element, click [here](https://support.wix.com/en/article/velo-tutorial-using-recaptcha-to-protect-data-submission).

To use the Captcha API, import `captcha` from the `wix-captcha.v2` module:

```javascript
    import captcha from 'wix-captcha.v2';   
```
