# MM Lite API and Connection

## What is MM Lite API?

Marketing Messages Lite API (MM Lite API) is an optimized version of the API for sending WhatsApp marketing templates. MM Lite was developed by Meta as a tool that reduces spam levels and helps companies deliver advertising content more effectively through optimized internal delivery.

This solution is ideal for mass marketing campaigns, promotions, new product notifications, etc. It uses the same template structure as the standard Cloud API — no need to create new templates.

{% hint style="warning" %}
**The transition to MM Lite API must be completed by January 1, 2026.**

You can continue sending marketing messages through Cloud API, however Meta will charge an additional fee of +7% for each marketing message after the specified date. Therefore, enabling MM Lite API in your WABA account is a more cost-effective option.
