Customizing Stripe Checkout | Implementing Basic Payment Flows with Stripe Checkout | Stripe for Next.js: A Developer's Guide to Seamless Payments

While Stripe Checkout provides a beautiful and functional out-of-the-box experience, you'll often want to tailor it to match your brand's aesthetic and provide a more personalized user journey. Thankfully, Stripe offers several powerful ways to customize Stripe Checkout, both visually and functionally.

One of the most straightforward ways to customize is by passing arguments to the stripe.redirectToCheckout function. These arguments allow you to influence the look and feel of the checkout page directly from your Next.js application.

const stripe = require('stripe')('sk_test_YOUR_SECRET_KEY');

const checkoutSession = await stripe.checkout.sessions.create({
  payment_method_types: ['card'],
  line_items: [
    {
      price_data: {
        currency: 'usd',
        product_data: {
          name: 'T-shirt',
        },
        unit_amount: 2000,
      },
      quantity: 1,
    },
  ],
  mode: 'payment',
  success_url: 'http://localhost:3000/success',
  cancel_url: 'http://localhost:3000/cancel',
  // Customization options below
  billing_address_collection: 'required',
  shipping_address_collection: {
    allowed_countries: ['US', 'CA'],
  },
  display_items: [
    {
      item_description: 'Premium Cotton T-shirt',
      item_name: 'Custom T-shirt',
      item_amount: 2000,
      item_currency: 'usd',
    },
  ],
  client_reference_id: 'user123',
});

res.status(200).json({ sessionId: checkoutSession.id });

Let's break down some of these key customization parameters:

billing_address_collection: Controls whether Stripe prompts customers to provide their billing address. Options are 'auto' (Stripe decides based on product) or 'required'.

shipping_address_collection: Allows you to specify which countries are allowed for shipping. If set, Stripe will prompt for a shipping address. You can use allowed_countries to restrict options.

display_items: Provides more granular control over how individual items are displayed on the checkout page, including descriptions and custom names.

client_reference_id: A unique identifier you can use to associate the checkout session with your internal order or user ID. This is incredibly useful for tracking and reconciliation.
