reCAPTCHA can help automatically protect your custom payment forms from excessive declines occurring due to card testing, spam, and other fraud. We strongly recommend that you set it up and use it.
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.
If you find the Default Score Threshold setting is not reducing card testing, spam, etc., you can switch to the Aggressive setting which will be more stringent in its analysis.
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.
