websiteURL	String	Yes	The full URL of target web page where the captcha is loaded. We do not open the page, not a problem if it is available only for authenticated users
websitePublicKey	String	Yes	ArkoseLabs CAPTCHA public key. The public key can be found in the value of the `data-pkey` parameter of the `div` element FunCaptcha, or you can find an element named (name) `fc-token` and from its value cut out the key that is specified after `pk`.
funcaptchaApiJSSubdomain	String	No	Custom subdomain used to load the captcha widget, like: `sample-api.arkoselabs.com`
data	String	No	Additional data payload object converted to a string with `JSON.stringify`. Example: `{\"blob\":\"BLOB_DATA_VALUE\"}`
