MM API is Meta's next-generation marketing solution built to enhance the customer experience and deliver the right message to more of the right people. Unlike Cloud API — which applies no delivery intelligence to marketing messages — MM API uses quality-based optimization to prioritize high-engagement sends, resulting in up to +9% higher delivery rates vs. Cloud API, validated by Meta's own A/B test across 12M+ messages.
> Every marketing campaign your sub-accounts run on Cloud API today is missing delivery, conversion tracking, and creative capabilities that are only available on MM API. The upgrade takes minutes.
Optimization
Quality-Based Delivery: MM API factors message engagement signals into delivery decisions — prioritizing messages that are expected, relevant, and timely. Cloud API has no equivalent. Result: up to +9% higher delivery for high-engagement messages.
Automated Creative Optimizations (Pilot): Meta automatically enhances the visual appeal of marketing templates — including image animation and filtering — to improve performance without any manual effort.
Richer Message Formats
Animated GIF Headers: Send GIF media in message template headers. Not supported on Cloud API.
Android App Deep Links: Send links that directly open your app on a customer's phone. Not supported on Cloud API.
All existing formats supported: Media, carousel, product catalog, flow, interactive list, interactive reply, and more — everything Cloud API supports, plus the above.
Measurement & Guidance
Tailored Recommendations: Receive evidence-based suggestions to improve future campaign performance. Exclusive to MM API.
Cost Metrics: Spend per Template, Cost per Click, and Cost per Delivery — available on both MM API and Cloud API.
Basic Metrics: Sent, Delivered, Read, Clicked, Errors — available on both.
Onboarding & Technical
Existing phone numbers and MM templates work as-is — no re-creation needed.
Coexistence supported — WhatsApp Business App users can be onboarded without disruption.

Deliver more messages to the right people without increasing send volume
