原文外掛簡介
Since mid-2025 Meta no longer supports native on-platform checkout for Facebook and Instagram shops. Merchants must instead configure a Checkout URL on their own website — Meta documents this approach in the Commerce Platform Checkout URL setup guide. That URL should pre-fill the store cart and send customers straight to checkout.
CartBridge Checkout Links for WooCommerce handles this seamlessly. You configure your store URL as the checkout URL in Meta Commerce Manager and the plugin takes care of the rest: it reads the product list from the URL, fills the WooCommerce cart, and redirects the customer to the checkout page.
How it works
Meta appends a products query parameter to your checkout URL every time a customer taps “Buy” on your Facebook or Instagram shop listing:
https://yourstore.com/checkout?products=wc_post_id_123:2,wc_post_id_456:1
The plugin intercepts this request, adds the right products (and quantities) to the cart, and bounces the customer to /checkout in one smooth redirect.
Supported product ID formats
wc_post_id_123:2 — simple product with WooCommerce post ID 123, quantity 2
wc_post_id_123_variation_456:2 — variable product 123, variation 456, quantity 2
123:2 — plain WooCommerce post ID (fallback format)
Optional parameters
coupon=CODE — applies a coupon code automatically
utm_source, utm_medium, utm_campaign, utm_content, utm_term — forwarded to the checkout URL for analytics
fbclid, cart_origin — forwarded for Meta attribution
Setup
Install and activate the plugin.
Follow Meta’s official Checkout URL setup guide.
In Meta Commerce Manager → Settings → Checkout, choose Checkout on another website.
Set the Checkout URL to your store’s checkout page, e.g. https://yourstore.com/checkout.
Meta will automatically append the ?products=… parameter when a customer buys.
Security
All query-string values are sanitised before use.
Product IDs are validated against the WooCommerce catalogue; non-existent or non-purchasable products are silently skipped.
Quantities are capped at 99 per item; item count is capped at 50 per request.
The final redirect uses wp_safe_redirect().
Requirements
WordPress 6.0 or later
WooCommerce 7.0 or later
PHP 7.4 or later
