MM Lite API (Marketing Messages Lite)

Definition

The Marketing Messages Lite API (MM Lite) is a Meta-built alternative to the standard Cloud API send endpoint, purpose-built for Marketing-category templates. Instead of delivering a marketing message immediately on send, MM Lite hands delivery to Meta's optimisation systems — the same machine-learning infrastructure behind Meta ads — which can adjust send timing per recipient and optimise toward outcomes like reads, clicks, or conversions (fed back via the Conversions API). Launched broadly in 2025 through BSPs and tech providers, MM Lite uses the same approved marketing templates, the same per-message marketing pricing, and the same WABA; only the delivery path changes. Utility, authentication, and service traffic stays on the standard Cloud API.

How it applies in India

India is a primary MM Lite market given its marketing-message volume and Meta's push to lift campaign ROI as per-user caps tighten organic reach. For Indian D2C brands the pitch is concrete: let Meta pick the delivery moment per user instead of blasting the full list at 11 a.m., and feed purchase events back through the Conversions API so delivery optimises toward buyers, not just readers. Adoption runs through your BSP — the API is not something merchants integrate directly. Meta revises MM Lite availability and features periodically; check current BSP support.
