What is Marketing Messages Lite API (MM Lite)?

Marketing Messages Lite API, known as MM Lite, is a streamlined endpoint Meta introduced for sending marketing template messages on WhatsApp. It is purpose-built for promotional sends and reduces the integration complexity compared to the full Cloud API send flow.

MM Lite adds delivery intelligence: Meta can optimize send timing and delivery to improve the chance that marketing messages reach engaged users, and it is designed to work alongside performance signals from campaigns. It handles marketing-category messages specifically, while utility and authentication traffic continues through standard endpoints.

For high-volume marketers, MM Lite aims to improve marketing message performance while keeping the technical lift low.
