About the shopping button
The shopping button (
on Android or
on iPhone) gives WhatsApp users direct access to your catalog on the WhatsApp Business app. Users can access the button directly from their chat with you, making it easier for them to explore your products and services while chatting with you directly.
To make the shopping button available to your customers, you must have an account registered to the WhatsApp Business app and have set up a catalog. If you meet those requirements, the shopping button will automatically appear to your customers in their chats with you.
