Payment Integration
In a production store, your payment form would appear here. Two common approaches:
Embedded Form (e.g. Stripe Elements)
A secure, pre-built card form is embedded directly into your checkout page. The payment provider handles PCI compliance — your server never touches card data.
API / Server-Side (e.g. PayPal, Square)
Your server creates a payment intent via the provider's API, then redirects or confirms on the client. The flow looks like:
Client → Your API → Payment Provider → Confirmation
