Using PayPal Smart Button in non-Ecommerce Site

When I test my PayPal smart button on a published “[domain].webflow.io” site, it brings up a checkout modal using PayPal’s “sandbox” feature. I am currently using a CMS only site. Do I have to have an Ecommerce site in order to use the PayPal button?
