Can REP AI edit a shopper's cart in chat? Yes, on Shopify
Yes: REP AI's sales agent can add, remove, re-quantity, swap and clear items in a shopper's cart from the chat, and each change lands in Shopify's own cart in the shopper's browser. It handles several items in one request, swaps a variant only when there's enough stock for all of it, and always asks for a yes before clearing the cart.

Several items at once
Ask for two things at once, and both land in one action, not one at a time.
Change quantities or remove
Quantity changes work both ways: set it to three or just add one more. And "drop the shoes" is enough. It resolves what you meant from the conversation.
Lands in the real cart
These aren't chat-only changes. The widget executes them on Shopify's own cart in the shopper's browser.
Swap a variant
A swap only happens if the target variant can cover it in full. Short on stock and the cart stays exactly as it was.
Clearing asks first
Clearing is the only irreversible one, so it never happens on the first ask. No confirmation, no directive.
Common questions
Can REP AI add products to a shopper's Shopify cart from the chat?
Yes. Shoppers can ask for several items at once, and the widget makes the change on Shopify's own cart in their browser.
What happens if a size or colour swap is short on stock?
A swap only happens if the target variant can cover the full quantity; if it can't, the cart stays exactly as it was.
Can REP AI clear a shopper's cart by mistake?
Clearing is the only irreversible action, so it never happens on the first ask; the shopper has to confirm it.
