Fixes the empty cart from Facebook &amp; Instagram Shops: Meta checkout URL products, quantities and coupons land in your WooCommerce cart.

WPRobo Checkout URL Bridge for Meta Shops

Meta no longer supports checkout on Facebook and Instagram. Shops must send 
buyers to your website with a Meta checkout URL carrying the cart as 
parameters. Out of the box, many of those clicks end in an empty 
WooCommerce cart — because Meta catalogs send retailer IDs (like 
 wc_post_id_123), SKUs, or composite IDs that WooCommerce doesn&#8217;t recognise. 
Every one of those is a lost sale.
WPRobo Checkout URL Bridge for Meta Shops makes your store a fully 
compatible Meta checkout destination. Zero configuration: install, activate, 
submit your checkout URL in Commerce Manager, done.
<h4>What it does</h4>
<ul>
<li>Reads Meta&#8217;s <code>products</code> parameter (any quantity of items).</li>
<li>Resolves every ID format: WooCommerce IDs, <code>wc_post_id_</code> retailer IDs, 
SKUs, variation SKUs, and <code>SKU_ID</code> composites.</li>
<li>Clears the cart on each visit so buyers see exactly what they picked.</li>
<li>Validates stock and tells the buyer if something is unavailable — never a 
silent empty cart.</li>
<li>Validates and applies the <code>coupon</code> parameter with a visible discount.</li>
<li>Preserves <code>utm_*</code>, <code>fbclid</code> and <code>cart_origin</code> for your analytics.</li>
<li>Adds nothing to your database, makes no external calls, has no settings.</li>
</ul>
