Popup checkout overview
Learn how popup checkouts work and how to create, configure, and launch them on your website.
Popup checkouts open in a modal window directly over your site, giving buyers a seamless, same-page checkout flow. FastSpring securely hosts the checkout, processes payments, and delivers fulfillment while maintaining a consistent look and feel with your brand.
Security note: Always use HTTPS for pages that host a popup checkout. This prevents browser security warnings and protects buyer data.
