Hosted Payment Page

The Hosted Payment Page (HPP) is a secure, white-label checkout that you embed into your own website through an iframe. It collects and tokenizes card data inside an isolated security context, so your servers and pages never handle raw card numbers — keeping you out of PCI scope while preserving your branding and user experience.

Your backend creates a short-lived payment session (authenticated via OAuth 2.0); your frontend loads a small SDK and mounts the iframe using the returned session token. The customer pays inside the iframe, and you receive the result via JavaScript callback or server-side redirect.


How It Works

1. Your backend creates a session   →  POST /api/sessions/create (OAuth) → sessionToken
2. Your frontend loads the SDK       →  <script src=".../iframe.min.js">
3. SDK mounts the iframe             →  Token sent via postMessage (never in the URL)
4. Customer pays inside the iframe   →  Card tokenized + processed by the gateway
5. Result returned to your page      →  onSuccess / onError callback (or redirect)
6. Your backend confirms the result  →  Verify status before fulfilling the order

Key Features

FeatureDescription
PCI Scope ReductionCard data is entered and tokenized inside the iframe — your servers never see raw PAN/CVC
White-LabelCustom CSS, tenant logo, brand color, and configurable billing fields keep the checkout on-brand
OAuth-Secured SessionsSessions are created server-side with OAuth 2.0 Client Credentials; the secret never reaches the browser
Short-Lived Session TokensJWT session tokens expire in 15 minutes by default and are passed via postMessage, never in the URL
Card & ACHSupports card payments and ACH bank transfers (via Plaid bank linking)
3D SecureWhen a CHALLENGE is returned, the iframe handles the ACS redirect and re-verification automatically
Auto-ResizingThe iframe reports its own height (RESIZE_IFRAME) so it fits your layout without a fixed height

Use Cases

  • E-commerce checkout — Drop a compliant payment form into your existing cart flow without building or hosting card fields
  • Subscriptions & saved cards — Collect a card for one-time or recurring use with the optional "save card" prompt
  • Card or account validation — Run a zero-amount card check or bank-account validation before a later charge
  • Branded payment pages — Apply your own CSS and branding for a seamless, on-brand checkout experience
