Embed styleable checkouts with Checkout Components (beta)
June 15th, 2026
Embed a fully styleable, PCI-compliant checkout directly into your site or app using the new FastSpring Checkout Components library. Available via npm as @fastspring/checkout-sdk, this beta release provides the frontend tools to build dynamic UIs while FastSpring handles payment capture, tax, and fraud screening.
- Embed secure payment elements: Mount the required Card, Pay Button, and Disclosures components directly onto your page using secure iframes to remain out of PCI scope.
- Customize the UI: Apply per-state style overrides to seamlessly match your site's exact branding.
- Manage configurations centrally: Use the new Seller App Dashboard to configure your checkout settings, allowed domains, and currencies in one place.
- Jumpstart your integration: Access drop-in styling templates and an exhaustive Style API property reference in our [Checkout Components Examples repository on GitHub] to speed up your initial build.
Note: Checkout Components is currently in beta and is not enabled by default. To request access, contact your Customer Success Manager or FastSpring Support.
