Send Catalog Template Messages

POST Method

Catalog templates are marketing templates that allow you to showcase your product catalog entirely within WhatsApp. Catalog templates display a product thumbnail header image of your choice and custom body text, along with a fixed text header and fixed text sub-header. When a customer taps the View catalog button in a catalog template message, your product catalog appears within WhatsApp.
