Welcome to Stripe Checkout!
Stripe Checkout is a pre-built, hosted payment page. Stripe handles the hard parts — security and compliance — so you never touch raw card details.
How Stripe Checkout Works
How Checkout works: your server creates a session, the customer is redirected to Stripe's secure page to pay, then sent back to your site afterward.
The Checkout Session Object
The Checkout Session object describes the payment: the line_items being bought, the mode, and the success and cancel redirect URLs.
Setting Up Your Server
To create a session you need a small server (Node, Python, Ruby, PHP, etc). Install the Stripe library and init it with your secret key — never expose it client-side.
Creating a Checkout Session
Here's how to create a one-time Checkout Session on your server. Swap in your real secret key; it prints the session ID and URL.
const stripe = require('stripe')('sk_test_YOUR_SECRET_KEY');
async function createCheckoutSession() {
try {
const session = await stripe.checkout.sessions.create({
line_items: [
{
price_data: {
currency: 'usd',
product_data: {
name: 'CoddyKit Course',
},
unit_amount: 1999, // $19.99
},
quantity: 1,
},
],
mode: 'payment',
success_url: 'https://example.com/success?session_id={CHECKOUT_SESSION_ID}',
cancel_url: 'https://example.com/cancel',
});
console.log('Checkout Session created:');
console.log(' ID:', session.id);
console.log(' URL:', session.url);
} catch (error) {
console.error('Error creating Checkout Session:', error.message);
}
}
createCheckoutSession();Redirecting to Checkout
The server returns a session.url; your client then redirects the user there with window.location.href = session.url to reach Stripe's secure page.
Handling Success & Cancel
After paying or cancelling, the customer returns to your success_url or cancel_url. The success URL can carry the session ID for confirmation.
Retrieving Session Details
On the success page, use the session_id to retrieve the full session on your server. That confirms payment status before you fulfill the order.
Security & PCI Compliance
Checkout's big win is security: Stripe handles all card data, your server never sees card numbers, and your PCI compliance burden drops dramatically.
