Meta has made Coexistence official: businesses can now onboard to the WhatsApp Business Platform using their existing WhatsApp Business App account and phone number, and run both the app and the Cloud API on that same number at the same time. Until now, moving to the Cloud API for automation, chatbots, or CRM integration usually meant giving up the native app entirely. This change removes that trade-off and is one of the more practical updates for small and mid-sized businesses in years.
What changed, according to Meta's changelog
Meta's official WhatsApp Business Platform developer changelog confirms that a Coexistence onboarding guide has been added to the Marketing Messages Lite (MM Lite) API. Businesses using the free WhatsApp Business App can now onboard to the Cloud API without migrating away from the app or losing their number and chat history. In effect, a business can keep its team using the familiar app interface for day-to-day conversations while also connecting the same number to the Cloud API for automation, broadcasts, and third-party integrations.
Industry coverage tracking the platform's roadmap through late 2025 and early 2026 describes this as a structural shift rather than a minor feature, noting that the ability to run the app and Cloud API simultaneously on one number changes what the product fundamentally is: no longer a choice between simplicity and automation, but both at once.
Other changes bundled with this update
- Marketing Messages Lite API is now generally available. This is a separate, lighter-weight connection specifically for high-volume marketing traffic, distinct from the regular Cloud API used for transactional and service messaging.
- Flows on WhatsApp Web. Starting early December 2025, users can open, complete, and view WhatsApp Flow responses directly in WhatsApp Web, not just on mobile devices.
- More self-service API controls. Businesses can now request Official Business Account status and edit their display name directly via API, tasks that previously required manual steps in WhatsApp Manager.
- Shorter media retention windows. Media retrieved via a media ID from a webhook is now downloadable for only 30 days, and after October 9th this shrinks further to 7 days. Businesses that archive customer-sent images or documents need faster download and storage workflows to avoid losing data.
Why this matters for Indian businesses specifically
India has one of the largest bases of WhatsApp Business App users in the world, spanning local shops, clinics, salons, and D2C sellers. Many of these businesses avoided the Cloud API specifically because it meant losing the app's simple, familiar interface for their staff, even though they wanted features like order bots, CRM sync, or broadcast campaigns. Coexistence removes that dilemma directly: a business can keep front-desk staff answering on the app they already know, while automation, catalog sync, and marketing campaigns run through the API in the background on the exact same number.
This is particularly relevant for businesses that are testing WhatsApp commerce or support automation for the first time. Instead of a risky, all-or-nothing migration, a business can now layer API-based tools on top of existing operations and phase in automation gradually.
What businesses should do next
Businesses already using the WhatsApp Business App who are considering automation should check whether their current provider or the tools they plan to use support Coexistence onboarding, since this requires connecting through the official onboarding flow rather than a fresh number setup. Businesses that store customer-sent media for records, compliance, or order verification should also review their download workflows now, given the tightened 7-day retention window after October 9th.
Frequently Asked Questions
Do I lose my chat history or number if I set up Coexistence?
No. Coexistence onboarding is designed to let you keep your existing WhatsApp Business App account and phone number while adding Cloud API access on top, rather than requiring a fresh migration.
Does Coexistence mean the WhatsApp Business App becomes free automation software?
No. The app itself remains a manual messaging tool for staff. Automation, bots, and broadcast campaigns still run through the Cloud API layer connected to the same number; Coexistence just lets both operate together instead of forcing a choice.
Is the Marketing Messages Lite API the same as the regular Cloud API?
No. It is a separate, lighter-weight connection built specifically for high-volume marketing message traffic, distinct from the standard Cloud API used for transactional and customer service messaging.
What happens to old customer media after the retention window closes?
Media retrieved via a media ID from a webhook becomes downloadable for a limited time only, now 30 days and dropping to 7 days after October 9th. After that window, the media is no longer retrievable through that media ID, so businesses needing to archive files must download them promptly.
