## Description

CheckoutBridge acts as a high-performance, enterprise-grade headless bridge between
WooCommerce and external custom landing pages (built in React, Next.js, Vue, Laravel,
PHP, Python, Node.js, Go, or static HTML).

It maintains WooCommerce as the single source of truth for product pricing, inventory
tracking, order management, and analytics, while enabling frictionless 1-click checkout
on external sales funnels.

### Key Features

 * **Single Source of Truth**: Product pricing, inventory deduction, and order creation
   logic executed securely on WooCommerce.
 * **Multi-Product Payload Ingestion**: Supports single or multi-product item selection
   with custom order quantities per line item.
 * **Real-Time Dynamic Coupon Validator**: Dedicated `/validate-coupon` REST endpoint
   for real-time promo code validation and discount calculation.
 * **Server-Side Meta (Facebook) Conversions API (CAPI)**: Automatic server-to-server
   SHA-256 hashed Purchase event dispatch directly to Meta Graph API on Processing
   order status.
 * **Global Dual-Shield Anti-Bot Engine**: E.164 international phone number normalization
   and Client IP velocity rate limiting to eliminate spam orders.
 * **Stateless Signed Redirect Tokens**: Secure HMAC SHA-256 tokens for tamper-proof
   thank-you page receipt rendering.
 * **WAF & Shared Host Shield**: Base64 payload decoding and custom headers to bypass
   aggressive host firewall filters (Imunify360, LiteSpeed, ModSecurity).
 * **In-Admin Developer Center**: Complete integration documentation with interactive
   code snippets for 8 programming languages.

### External Services

This plugin can optionally connect to an external third-party service:

#### Meta (Facebook) Graph API / Conversions API

 * What the service is and what it is used for:
    When enabled by the site administrator
   in a Bridge Campaign, CheckoutBridge connects to the Meta (Facebook) Graph API(
   Conversions API) to send server-side “Purchase” events to track conversions, 
   measure ad effectiveness, and attribute sales in Meta Ads Manager.
 * What data is sent and when:
    Data is only sent when the store administrator explicitly
   enables Meta Conversions API for a bridge campaign AND an order created through
   that bridge transitions to the “Processing” status. Data sent to `https://graph.
   facebook.com/` includes:
    - Cryptographically hashed customer data (SHA-256): Customer email, normalized
      phone number (E.164), first name, last name, city, and 2-letter country code.
    - Unhashed technical and tracking metadata: Customer IP address, browser user-
      agent string, Facebook click ID (`_fbc`), and Facebook browser ID (`_fbp`).
    - Order details: Order currency, order total value, item product IDs, quantities,
      and unit prices.
 * Service Provider:
    Meta Platforms, Inc.
 * Service Endpoint:
    https://graph.facebook.com/
 * Terms of Service and Privacy Policy:

## Installation

 1. Upload the `op-checkoutbridge` directory to your `/wp-content/plugins/` directory.
 2. Activate the plugin through the ‘Plugins’ menu in WordPress.
 3. Ensure **WooCommerce** is active.

## FAQ

### Do I need to enable WooCommerce REST API keys?

No. CheckoutBridge uses standalone, high-performance campaign token keys (`op_cb_...`)
with CORS domain whitelisting, eliminating complex WooCommerce API key management.

### Is High-Performance Order Storage (HPOS) supported?

Yes! CheckoutBridge is fully compatible with WooCommerce HPOS native storage.
