Use AI to understand what a shopper wants and propose a cart; use your trusted server-side application to decide what can actually be bought and charged. For a typical one-time order, validate the cart, create a Stripe Checkout Session in payment mode with explicit line items, and handle order follow-up from Stripe’s checkout.session.completed event.
How the AI-assisted purchase flow works
- Collect shopping preferences. Let the shopper describe products, options, quantities, budget, or other preferences in natural language.
- Turn the request into a proposed cart. The AI can suggest items or help the shopper select from your catalog. Present the proposed products and quantities clearly so the shopper can review them.
- Validate the cart in your application. On your server, resolve product identifiers against your catalog and check current prices, quantities, stock, and merchant rules. Do not use an AI-generated price or product description as the authority for what to charge.
- Create a fresh Checkout Session on the server. Configure it for the transaction and redirect the shopper to Stripe-hosted Checkout, or use an embedded Checkout approach.
- Process the payment outcome and order follow-up. Use Stripe’s completion event to coordinate post-payment work, such as sending an order confirmation.
Stripe describes a Checkout Session as the customer’s session for a one-time purchase or subscription. Its Checkout Sessions API reference recommends creating a new Session each time a customer attempts to pay.
Choose the Checkout interface
Stripe offers a hosted Checkout page, an embedded payment form, and embedded components using Elements with the Checkout Sessions API. The hosted option redirects the shopper to a Stripe-hosted page; embedded approaches keep the payment UI on your website. Compare the options against your desired payment flow and interface needs using Stripe’s Checkout integration documentation, which links to current feature details.
| Approach | Where the payment UI appears | What to consider |
|---|---|---|
| Stripe-hosted Checkout | On a Stripe-hosted page | Your server creates the Session and sends the customer to its URL. Check Stripe’s current documentation for feature availability relevant to your flow. |
| Embedded payment form | Within your website | Choose this when keeping the payment form on your site is part of the integration need; confirm current feature details in Stripe’s documentation. |
| Embedded components with Elements and the Checkout Sessions API | Within your website | Choose this when you need an embedded approach; confirm current feature details in Stripe’s documentation. |
Set the Session mode and line items
For a standard one-time ecommerce order, create the Session with mode: "payment" and explicit line_items. Stripe’s API reference lists three modes: payment for one-time purchases, subscription for recurring purchases, and setup for saving payment details to charge later. Line items are required for payment and subscription Sessions. Use the mode that matches the actual transaction rather than treating every AI-assisted order as a one-time payment.

Pass line items based on the validated catalog products and quantities. Stripe documents creating the Session on your server; keeping product and price decisions in trusted application logic is the practical way to prevent a suggested cart from becoming an unverified charge. The retrieved Stripe documentation does not describe a special AI Checkout feature or an AI-specific standard.
Connect the Session to your order
Choose Session fields to fit your actual order process. The Session create API documents fields including client_reference_id for referencing a customer or cart in internal systems, metadata for structured key-value information, customer identifiers or email, automatic tax, shipping collection and shipping options, and success or return URLs. Some fields are conditionally required or disallowed depending on the Session mode and interface configuration, so do not copy a configuration without checking its conditions.

- App sends deposits to your bank account within 1 to 2 business days, or enjoy instant deposits (fees apply).
A useful implementation pattern is to associate the Session with an internal cart or order record using an appropriate reference, then use the resulting Stripe event to coordinate order follow-up. Stripe’s existing-customer Checkout guide describes a website button calling a server-side endpoint to create a Session. Stripe sends checkout.session.completed when a customer completes a Checkout Session payment; the guide gives sending an order confirmation email as an example of follow-up work.
Handle completion with Stripe’s event flow
Do not treat a shopper’s arrival at a browser success page as, by itself, proof that your order should be fulfilled. Use Stripe’s documented checkout.session.completed event to coordinate post-payment actions. The event-driven approach ties follow-up to Stripe’s payment completion signal rather than relying only on a redirect in the customer’s browser.
