內容簡介
### 總結
運行多個 WooCommerce 商店常常會造成相同的運營問題：庫存漂移。透過 Kitgenix Stock Sync for WooCommerce，這個外掛提供了一個安全、實用的模式來解決這個問題，讓一個 Master 商店持有權威性的庫存狀態，供應一個或多個 Child 商店接收更新。
### 問題與答案
1. 這個外掛主要解決什麼問題？
- 答：Kitgenix Stock Sync for WooCommerce 主要解決運行多個 WooCommerce 商店時庫存漂移問題。
2. 這個外掛的設計原則是什麼？
- 答：這個外掛設計為輕量級，不使用第三方 SaaS，也不使用自訂數據庫表，而是使用 WooCommerce 和 WordPress 的原始元素來同步庫存。
3. 這個外掛同步哪些庫存狀態？
- 答：該外掛同步每個 SKU 的庫存狀態，包括庫存數量、庫存狀態、可訂購的庫存量和低庫存量。
4. 如何處理 SKU 變更同步？
- 答：這個外掛支持 SKU 變更同步，透過維護一個內部穩定的識別符號（“GID”），當 Master 上的 SKU 變更時，插件會發出一個 sku_rename 事件，使用 GID 讓 Child 商店可以安全地映射更新。
5. Child 商店可以啟用什麼功能？
- 答：Child 商店可以選擇啟用 Strict checkout validation，這在結帳過程中提供嚴格的驗證。
這些問題與答案可以使用 HTML 的項目符號清單（bulleted list）來呈現。
原文外掛簡介
Running multiple WooCommerce stores often creates the same operational problem: stock drift.
You update stock on one site, but another site still shows the old quantity. That can lead to oversells, customer frustration, and messy fulfilment.
Kitgenix Stock Sync for WooCommerce solves this with a secure, practical model:
One Master store holds the authoritative stock state.
One or more Child stores receive updates from the Master.
Stores communicate over signed REST requests (HMAC SHA-256) with timestamp + nonce replay protection.
This plugin is designed to be lightweight:
– No third-party SaaS.
– No custom database tables.
– Uses WooCommerce + WordPress primitives (REST API, options, product meta, transients, WooCommerce logging, Action Scheduler).
What this plugin syncs
Stock state is synced per SKU, including:
– stock quantity
– stock status
– backorders
– low stock amount
Note: this plugin is focused on inventory syncing. It does not sync pricing, product content, images, or orders.
How it works (high level)
1) Stock changes are captured on each store using WooCommerce stock hooks.
2) Children send events to the Master; the Master applies incoming events locally and then pushes authoritative stock state out to all enabled children.
3) The Master can also run a Reconcile operation to push stock state for all products in batches.
SKU rename sync (important)
This plugin supports SKU renames by maintaining an internal, stable identifier (a “GID”) stored as product meta:
– _kitgenix_stock_sync_for_woocommerce_gid
When SKUs change on the Master, the plugin emits a sku_rename event using the GID so child stores can map the update safely.
Tip: Run Reconcile on the Master after initial setup. Reconcile establishes stable GIDs for products that don’t already have one, which makes SKU rename sync reliable.
Strict checkout validation (Child)
Child stores can optionally enable Strict checkout validation:
– During checkout, the child queries the Master’s stock for SKUs in the cart.
– If the Master reports the SKU is out of stock or insufficient (with backorders disabled), checkout is blocked.
– If the Master can’t be reached, validation is fail-open to avoid breaking checkout.
Exclusions
You can exclude SKUs (comma or new line separated). Excluded SKUs are ignored for:
– outbound stock events
– reconcile batches
– strict checkout validation
– audit checks
Tools & diagnostics included
From the plugin admin screen:
– Test Connection (ping the configured store)
– Reconcile (Master): push authoritative stock state to all children in batches
– Manual SKU Sync (Master): push a specific set of SKUs to all children
– Audit Children (Master): query each child’s local stock fields and compare against the Master
– Event Log + Backlog: see recent events and failed pushes, and clear logs when needed
– Status: last inbound/outbound health timestamps and last error message
Quick Start
Install and activate the plugin on the Master and all Child stores.
Choose your role on each store:
Master: one store
Child: all other stores
On the Child store: set the Master connection (Master URL, Master Store ID, Shared Secret).
On the Master store: add each child (Child URL, Child Store ID, Shared Secret).
Use Tools → Test Connection.
On the Master store: run Tools → Reconcile to establish stable GIDs and push initial state.
Optionally enable Strict checkout validation on children.

This plugin does not otherwise connect to third-party services as part of its stock sync. It does make REST requests between your own WordPress sites (Master and Child stores). These requests may include:
– product SKUs
– stock state (quantity/status/backorders/low stock)
Strict checkout validation on children sends SKUs in the cart to the Master for stock verification.
Security & Privacy
No tracking cookies are added by this plugin.
Admin actions are protected with nonces and capability checks.
REST requests are authenticated using HMAC signatures with timestamp + nonce replay protection.
Shared secrets are stored in the plugin settings option (kitgenix_stock_sync_for_woocommerce_settings). Treat secrets like passwords.

– Site option: kitgenix_stock_sync_for_woocommerce_settings
– Transients by prefix: kitgenix_stock_sync_for_woocommerce_ and kss_ (covers dynamic keys such as nonce/seen/debounce helpers)
Multisite:

If you want to remove all plugin data, you can also delete:
– the product meta _kitgenix_stock_sync_for_woocommerce_gid (if you no longer need SKU rename mapping)
