WooCommerce Shipping (formerly WooCommerce Services) handles label purchases through Automattic's shipping rate API. When a label is bought from the order screen, the plugin writes the tracking number to _wc_shipment_tracking_items postmeta, sets the carrier code (USPS, DHL Express, etc.), and adds an order note. Many stores then move the order to wc-completed via the shipping admin, firing woocommerce_order_status_completed.

SleekPixel listens to that hook and to the WooCommerce Shipping label-purchase action. The card pulls order number, ship-to city or country (without exposing full address), carrier name, tracking number, and the line items being shipped. It renders into a branded shipping receipt layout, then writes the PNG to uploads with the meta key _sleekpixel_shipping_card attached to the order.

If the carrier delivers a status update via the WooCommerce Shipping tracking widget, SleekPixel can opt into regenerating the card with the new status (Out for delivery, Delivered, etc.). The order page's og:image reference always points to the latest version of the shipping card, so links shared on the day of delivery look different from links shared the day the label was purchased.

WooCommerce Shipping is the Automattic-maintained plugin that lets Woo stores buy discounted USPS and DHL labels directly from the order screen. Stores using it ship thousands of orders a month, often through one or two carriers, and each shipped order generates a customer-facing URL shared in shipped-order emails, customer dashboards, support tickets, and ops channels. In every one of those places, the default OG image is the storefront's homepage logo.

A USPS Priority shipment to a customer in Berlin looks identical to a DHL Express shipment to one in Tokyo in any preview. The carrier and tracking number, which are the two pieces of information a recipient most wants to see on a shipped-order link, are completely invisible. SleekPixel changes that by treating each shipped order as its own piece of social content.

The card carries order number, carrier badge, tracking number, and ship-to region, then ships as a real PNG attached to the order. When the link gets opened anywhere, the preview shows the shipment, not the storefront brand. That single difference makes shipped-order links readable to customers, support agents, and ops staff.
