With the tools activated (section 5), your agent can look up your catalog and put together a cart while chatting. Two real conversation examples: > **Note — Example — looking up the catalog** > > A customer asks whether you have a garment in a specific size. The agent uses "Search products in your catalog" and, if it finds it, "Look up a catalog product" to confirm sizes and price live — never outdated data. > **Note — Example — putting together the cart** > > The customer confirms they want to buy. The agent uses "Create a shopping cart" with the chosen products and shares your own store's payment link — the customer pays on Shopify, your agent never sees or touches the payment data. Shopify doesn't have its own piece in the **flow builder** today: its tools are available to any agent with access, within a normal conversation.
