Embedded Checkouts are a same-page checkout experience that enables your customers to purchase products without leaving your website. When a customer clicks **Buy Now**, your website uses the [Store Builder Library](https://developer.fastspring.com/reference/store-builder-library-overview) to create an order session and display the embedded checkout on the page you choose. You can fully customize its styling, localization, and field options to fit your store’s needs. After the buyer enters their payment details, FastSpring securely processes the transaction and delivers the fulfillment automatically. To preview your configuration, select **Save and Preview** in the top-right corner of the checkout editor. The preview displays a sample $14.95 monthly subscription using your current settings. > **Security note:** Always use HTTPS for pages that host an embedded checkout. This prevents browser warnings and protects your customers’ data.
