1. Click Get Key on the Google Recaptcha card (it opens google.com/recaptcha/admin/create) and register your site. Choose either v2 checkbox or v3.
2. Paste the keys into Google Recaptcha - Site Key and Google Recaptcha - Secret Key.
3. Set Google Recaptcha - Version to v2 - Checkbox (I'm not a robot) or v3 - Invisible (score based) to match the key type you created.

Once both keys are saved the card is Active and reCAPTCHA is enforced on customer registration, adding a payment card to a customer profile, and the website's built-in contact form. With v3 the visitor is accepted only if Google's score is at least 0.5 (adjustable by Sprwt support). Only the Google Recaptcha - Version setting is duplicated under Business: Integrations in Client Config — the Site Key and Secret Key are only editable from this card.
