Overview

Marketing messages with optimizations offer businesses the ability to leverage Meta’s AI system to drive performance for businesses and improve quality for users.

Meta is investing in Marketing Messages API (MM API) which would allow businesses to send marketing messages across Meta suite of business messaging products (starting with WA and then Messenger and IGD) leveraging Meta’s optimization tech on top of their Ad Platform. The objective is to drive higher ROI by optimizing the reach (audience, time and channel) to deliver messages to the people most likely to engage with them.

As this platform is totally outside of WA Cloud API with dynamic pricing and billing to the Business’s Ad account, Meta has created another lightweight integration called as “MM Lite” which is an interim solution to allow partners to transition from Cloud API to eventually MM API over MAPI and works only for WhatsApp.

MM Lite integration is built over the Cloud API and offers higher or neutral delivery rates using partial delivery optimizations (As compared to MM API) based on Meta Ad signals. This will eventually increase the delivery rates as compared to the Cloud API where because of frequency capping, the delivery rates have gone down.

Benefits of MM Lite

• Better delivery rates ( based on initial analysis from Meta).
• Business sending relevant/ quality messages to end users are not hurt from adhoc frequency capping.
• Better ROAS as conversion data is used to identify and prioritize sending messages that are optimized for return on spend.

STEP 1 : Onboarding For MM Lite

MM Lite onboarding is needed additionally to an existing WABA onboarding on Cloud API. It can be done in 2 ways -

1. It requires a partner to generate an Embedded Signup link for the customer which the customer (FBM) must go through to onboard their WABA to MM Lite. The ES flow is at a BMID level and hence no WABA or Phone selection/registration is required during the onboarding on MM Lite. All the WABAs under the BM are automatically registered on MM Lite after successfully completing the ES Flow. The link generated can expire in 5 days. If the WABA was on OBO model, it will be moved to a shared model during the ES Flow as a prerequisite of MM Lite API. If the WABA was on Onprem, it will NEED to be moved to Cloud API first.
2. To send onboarding request directly to your customer on their BM, please request to support [[email protected]] to run the mm lite intent for a given app.

Refer to article for steps needed by customer.

STEP 2 : Sending MM Lite Messages

1. Template creation - No special template creation. Existing templates created on Cloud API for marketing can be used in MM Lite as well. Partners can use this existing API to do the same.
2. Sending MM Lite messages - The syntax and payload of MM Lite send message API replicates that of Cloud API V3 send message API . Other messages (Auth, Service, Utility, free form) return an error in this API. V2 or V3 users both can use this new endpoint to send MM Lite messages.
3. Receiving webhooks : All incoming DLRs should be received and forwarded as per the existing mechanism. Webhooks / DLR payload will be the same as existing on V2 and V3, no change. Except - delivered, sent, read and billing event will indicate the message category as Marketing lite.

Pricing & Analytics

• Wallet statement will show 'marketing lite' deductions.
• Partner Analytics APIs remain same and will show the sum of CAPI marketing and MM Lite marketing in total, no bifurcation for now.

Meta Analytics

All analytics for a business’ marketing message templates sent via the MM Lite API are also available at:-

1. Ads Manager, on the “Marketing Messages” tab.
2. The Whatsapp Template Analytics API - In app events only.
3. If Businesses are using Meta Pixel and Conversions API to send conversion events (Add to card, purchase etc.) to Meta after customers are taking such actions on a Marketing message sent via MM API (Gupshup does not provide the Insights API as of now).
