An [hCaptcha](https://docs.yescaptcha.com/en/tasks/hcaptcha/) task needs `websiteURL` (the page showing the captcha) and `websiteKey` (the site key, a UUID); Enterprise sites sometimes also need `rqdata`. All can be found with the browser’s developer tools (F12).

## websiteKey

**Method 1: page source.** In the Elements panel press Ctrl+F (Cmd+F on Mac) and search for `data-sitekey`:

```html
<div class="h-captcha" data-sitekey="3ceb8624-1970-4e6b-91d5-70317b70b651"></div>
```

The `data-sitekey` value is the `websiteKey`.

**Method 2: network requests.** In the Network panel search for `hcaptcha` and find the `checksiteconfig` request; the value after `sitekey=` is the `websiteKey`:

```text
https://api.hcaptcha.com/checksiteconfig?v=...&host=example.com&sitekey=51829642-2cda-4b09-896c-594f89d700cc&sc=1&swa=1
```

## websiteURL

The full URL of the page that shows the captcha, **not** `hcaptcha.com`. The `host=` in the request above is that page’s domain.

## rqdata (Enterprise)

Some sites use hCaptcha Enterprise and issue an `rqdata` value each time the captcha loads; without it the token won’t pass. It usually appears in a response from the site’s own API (for example a `captcha_rqdata` field returned by a login call), or is passed to `hcaptcha.render` / `hcaptcha.setData`. Put it in the task’s `rqdata` field. It is usually single use, so fetch a fresh one each time.

## userAgent

`userAgent` must be the value returned by [`/useragent`](https://docs.yescaptcha.com/en/api/useragent/); submit the token with the `userAgent` returned in the result.
