NOTE: Currently, reCAPTCHA does not work with Stripe Checkout. It can still be used with Embedded and Overlay forms.
reCAPTCHA can help automatically protect your custom payment forms from excessive declines occurring due to card testing, spam, and other fraud.
Google’s reCAPTCHA works by preventing non-humans from interacting with your page, meaning that an attacker’s automated system will not be able to use your payment form.
To enable invisible reCAPTCHA, register your site with Google choosing the reCAPTCHA v3 type.
After registering you will be redirected to a page where you can retrieve the necessary credentials to enter into your WP Simple Pay Pro settings.
You will find the reCAPTCHA settings near the bottom of the Simple Pay Pro > Settings > General tab.
You’ll know things are set up correctly when you visit your website and see Google’s reCAPTCHA privacy and terms overlay in the lower right-hand corner of the page.
While not absolutely necessary, reCAPTCHA can protect your payment forms from card testing, spam, and other fraud. We recommend that you set it up and use it.
