How it differs from HPP (Hosted Payment Page):
| Dimension | HPP (Online Payments) | Billing Hosted Checkout |
|---|---|---|
| Core API | PaymentIntent + redirectToCheckout() |
billing_checkouts/create → returns url |
| Typical use case | One-off payments | Subscriptions / recurring billing / one-off invoices / card-only setup |
| Auto-created resources | None | Customer, Payment Source, Subscription |
Checkout Modes: SUBSCRIPTION · PAYMENT (one-off) · SETUP (card-saving only, requires x-api-version >= 2025-08-29)
