Keaz cover: setting up a WhatsApp product catalog for a Shopify store

In short

How to set up a WhatsApp catalog, which product message formats exist, and the commerce setting most stores miss. Based on Meta's docs, September 2026.

A WhatsApp catalog is a list of your products that you upload to Meta and connect to your WhatsApp Business account, so customers can browse items inside the chat instead of being sent to your website. You build it in Meta Commerce Manager or through the Commerce API, then decide, per phone number, whether the storefront icon and the shopping cart are switched on. What it is not is a checkout: outside India, an order placed in WhatsApp reaches you as a notification, and you still fulfil it in your own shop.

  1. 4 stages. Upload the inventory, set the commerce settings, share the products, handle the replies.
  2. 30 products fit into one multi-product message; a product carousel holds 10.
  3. 1 switch decides whether anyone finds the storefront at all — and it is off by default.

Set a catalog up when it has a job to do: a short range, a support conversation that needs to show a product, a chat people open to browse. Upload the inventory, then check the two commerce settings before you tell anyone the catalog exists — that second step is what separates a working storefront from an invisible one. The orders still land in your shop, and the messages that bring people back are still the part that earns the money.

Frequently asked questions

Do I need the WhatsApp Business API for a catalog?
A catalog is connected to a WhatsApp Business account, and the message formats that show products — single-product, multi-product and carousel messages — are documented for the WhatsApp Business Platform. The WhatsApp Business app has its own catalog surface, and the two behave slightly differently: as of 2026-09-18, Meta documents that product messages sent via the Cloud API do not display the shopping cart icon in the chat header the way app messages do.
How many products can I send in one message?
Up to 30 in a multi-product message, organised into sections you name, and up to 10 cards in a product carousel. A catalog message does not list products at all — it shows a thumbnail and a button that opens the full catalog inside WhatsApp.
Can customers pay inside WhatsApp?
Meta documents an in-chat checkout button for businesses based in India selling to WhatsApp users with Indian country calling codes. Elsewhere, a customer submits a cart, you receive the order details as a notification, and you process the order in your own shop.
Why can't customers see my catalog?
Most likely because the storefront is hidden. Catalog visibility is set per business phone number and defaults to off, so the storefront icon and the catalog buttons do not appear until you switch it on. The shopping cart, by contrast, is enabled by default.
