On a project that I was working on at my company, Shopify needed to check inventory in an ERP before allowing a product to be added to the cart. In this case, the inventory data existed only in the merchant's ERP and was not stored in Shopify. Instead of connecting Shopify directly to the ERP, I introduced a Cloudflare Worker as an intermediary layer. This allowed me to centralize communication with the ERP while keeping sensitive information away from the front end.
