Catalog allows current and potential customers to browse a business’s products or services, ask questions and engage with the business. Customers can choose a product or service they're interested in, share it with their friends or message the business to ask questions about that product.
To share a product or service from catalog:
The shared link will directly open the item/catalog if the recipient views the links within WhatsApp Messenger or WhatsApp Business app.
However, if the catalog link is shared over email or browser, a selector will open to allow the user to choose which app to open the link.
