Quick Answer
Can you send products from a catalog on the WhatsApp API?
Yes, if you have a Meta catalog connected to your WhatsApp Business account. Two message types use it: a single product message showing one item, and a multi-product message grouping up to thirty items into sections. Customers can browse and add to a cart inside WhatsApp, and the cart arrives back to you as an order webhook. The catch is that the catalog itself has to exist and stay accurate, which is where most implementations actually fail.

Sending Products from a WhatsApp Catalog

What you need before the API is relevant
The messages are the easy half. The work is the catalog: items, images, prices and availability, kept current. A product message that opens onto something out of stock is worse than no product message.
Connect the catalog to the WhatsApp Business Account and check it renders before you build sending logic, because a missing or unapproved catalog produces confusing errors at send time.
Where it stops
An order webhook is a statement of intent, not a payment. In most markets you still take money elsewhere, so treat the cart as a well-structured enquiry.
Product messages also suit a real catalogue of comparable goods. For services quoted per event, a list message or a link to a proper page is usually clearer than forcing them into catalog items.
