update_cart_lines

act imperative

Change the quantity of items already in the cart, or remove them. Every change here addresses an existing cart line by its id, so call get_cart first unless you already have line_items[].id from an earlier get_cart in this conversation. Pass the ABSOLUTE target quantity, not a delta — quantity 2 means the line ends up at 2 regardless of what it was. Use quantity 0 to remove the line entirely. Batch every change for ONE request into a SINGLE call — line_items accepts up to 10 entries; do NOT call update_cart_lines once per line. Batching applies WITHIN a single request: each new thing the user asks for later is its own call. This tool cannot add new merchandise. To add something not already in the cart, use add_to_cart. To empty the whole cart at once, use cancel_cart.
