General

 Website settings are a secret, super secure section of your website and tools. Only admins with developers have access to it. You can edit your payment gateway and other settings for products, content, fulfillment, compliance, and more within website settings. Changes in this section should not be taken lightly and can cause significant adverse issues on your website and POS. You should only change this section if you know what you're doing and have been adequately trained.

In short, you can mess up your website and POS if something isn't done correctly.
