WooCommerce Checkout Customization

Before writing code

Fetch live docs:

1. Web-search site:developer.woocommerce.com checkout for checkout documentation
2. Web-search woocommerce checkout blocks extensibility api for block checkout patterns
3. Web-search woocommerce classic checkout customization hooks for classic checkout hooks

Two Checkout Implementations

Classic Checkout (Shortcode-Based)

• Uses [woocommerce_checkout] shortcode
• PHP-rendered with WC_Checkout class
• Fully extensible via actions and filters
• Template: checkout/form-checkout.php

Block-Based Checkout (Default Since WC 8.3)
