WhatsApp said it is adding the new feature after an early positive response from some businesses that tested it recently.
Carts are aimed at making it easier for consumers to buy multiple items from a business, and for merchants to keep a better track of order inquiries and manage requests.
On WhatsApp, users will now see the option to add items to the cart. When done, users will be able to send the order request as a message to the business.
WhatsApp said carts are going live for users across the globe today.
