No‑Backend Payment Stubs: 6 Patterns to Capture First‑Dollar Signals Without Adding PCI Scope

What it is: Mount a PCI‑validated payment element (hosted iframe) from a payments provider on your frontend so the card number never touches your servers. You create a minimal server endpoint only to create a short‑lived intent or session; the payment UI and tokenization happen entirely in the browser. This is the canonical low‑scope approach used by Stripe Elements/Payment Element and similar hosted fields.

How to implement: Your backend creates a PaymentIntent or Checkout Session and returns a client_secret/session_id. The frontend mounts the provider’s Payment Element or hosted field; on submit the provider returns a token or confirms the intent. For a no‑capture test, create a PaymentIntent in 'capture_method=manual' or use a Setup Intent to vault the card without immediate settlement.

What it is: Use a provider‑hosted checkout page (a payment link or Checkout product) and redirect users to that page. You capture a completed payment or an intent without touching card data or embedding fields on your site. This is the simplest integration: generate a link on the server and send the user there.

How to implement: Generate a checkout session or payment link with a product/price and optional metadata (trial, cohort tag). For first‑dollar testing, create a small‑amount refundable charge or an authorization only flow if supported; return users to your app via success/cancel URLs and record the session result server‑side.

What it is: Send tokenized, single‑use links or email links that let a customer confirm payment without entering card data again. The link contains a short server‑generated token (not PAN) which, when opened, triggers a hosted confirmation page or a lightweight client flow that charges a vaulted payment method.

How to implement: On the first interaction use a Payment Element or Setup Intent to vault the card with the processor. Store only the processor’s token (payment_method ID). For follow‑up confirmations, issue signed, short‑lived URLs that call your server to create a capture or one‑time PaymentIntent using the stored token—no card data on your servers.

What it is: Place a card authorization only (hold) for a small amount to verify willingness‑to‑pay without immediate settlement. You then decide to capture later once the product ships or the feature is validated. This is commonly used for preorders and to test purchase intent.

How to implement: Create a PaymentIntent or transaction with capture_method=manual or use gateway auth parameters. Notify users clearly: an authorization may appear as a pending charge and can expire. Capture windows and regulations vary by card networks and processor—use small amounts and conservative hold durations for early tests.

What it is: Use a Setup Intent to tokenize and vault a payment method without charging. This gives you a payment method on file you can charge later—great for preorders or gated beta invites where you want to confirm a payment instrument but not take funds yet.

How to implement: Run a Setup Intent via a hosted element on the frontend. Store only the gateway token (customer.payment_method). For later billing, create a PaymentIntent server‑side that references the stored token and follows capture rules.
