Facebook recently added a shopping button in WhatsApp. The button will allow users to shop products directly from WhatsApp.
The shopping button ( on Android or on iPhone) gives you access to a business’ catalog directly from your chat screen, making it easy to explore a business’ products and services while using WhatsApp. You can still access the business’ catalog from their business profile.
This feature is currently only available to businesses that use the WhatsApp Business app.
Businesses must have set up a catalog for this button to appear.
