Worked on the woocommerce/woocommerce-gateway-stripe repository to enhance the reliability of Stripe webhook processing in WooCommerce multisite environments. Addressed a critical issue where Refund objects were incorrectly handled as orders, leading to fatal TypeErrors during payment workflows. Introduced a strict type check using PHP to ensure only WC_Order objects are processed in the get_order_from_intent function, effectively preventing webhook failures. This backend development effort improved uptime and reduced support incidents for sites sharing a Stripe account. The work demonstrated a strong focus on robust Stripe integration and careful handling of object types to maintain stable payment processing across multiple sites.
