WhatsApp Business App to WhatsApp Business API Using Meta Coexistence API

WhatsApp Business has evolved from a simple messaging tool into a full-fledged customer communication platform. While the WhatsApp Business App works well for small teams, it becomes limiting as businesses grow. This is where the WhatsApp Business API comes into play.

Until recently, migrating from the WhatsApp Business App to the WhatsApp Business API meant giving up the existing number and chat history. Meta changed that with the introduction of the Meta Coexistence API, allowing businesses to use both systems together during the transition.

In this guide, we’ll explain what Meta Coexistence API is, how it works, and how you can move from WhatsApp Business App to WhatsApp Business API smoothly using platforms like Whatsboost.

Why Businesses Outgrow the WhatsApp Business App

The WhatsApp Business App is designed for small businesses managing conversations manually. It works well initially but presents challenges as message volume increases.

Common limitations include:

• Single-device usage

• No multi-agent support

• Limited automation

• No CRM or tool integrations

• Manual follow-ups and tracking

For businesses handling leads, sales, and customer support at scale, these limitations quickly slow growth.

What Is WhatsApp Business API and Why It Matters

The WhatsApp Business API is built for medium and large businesses that need scalability, automation, and system integrations.

With the WhatsApp Business API, businesses can:

• Support multiple users on one number

• Automate conversations and follow-ups

• Integrate WhatsApp with CRMs and websites

• Send transactional and notification messages

• Track performance and conversations centrally

The API transforms WhatsApp Business from a chat app into a structured communication channel.

The Challenge of Migrating from App to API

Historically, migrating from the WhatsApp Business App to the WhatsApp Business API required:

• Deleting the WhatsApp Business App

• Losing access to the same number temporarily

• Disruption in customer communication

This created hesitation among businesses that relied heavily on their existing WhatsApp Business setup.

What Is Meta Coexistence API?

The Meta Coexistence API solves this exact problem.

Meta Coexistence API allows businesses to:

• Use WhatsApp Business App and WhatsApp Business API together

• Keep the same phone number active

• Transition gradually without disrupting conversations

This coexistence enables a smoother, safer migration path.

How Meta Coexistence API Works

With Meta Coexistence API:

• Incoming messages continue to arrive on the WhatsApp Business App

• Outgoing API-based messages can be sent via WhatsApp Business API

• Businesses can test automation and workflows before fully switching

This hybrid setup ensures continuity while unlocking API features.

Key Benefits of Using Meta Coexistence API

When Should You Move to WhatsApp Business API?
