Businesses using WhatsApp for sales and customer support often face one challenge—how to scale automation without giving up the WhatsApp Business App and its existing chats. Meta’s WhatsApp Coexistence API Solution (Coex) finally solves this problem.

With Coex, you can run the WhatsApp Business App and the WhatsApp Cloud API at the same time, on the same number, with seamless syncing and zero disruption.
If you want automation, broadcasts, workflows, and campaign power—without losing your chats—this guide breaks everything down in a simple, business-friendly way.

What Is the WhatsApp Coexistence API Solution?

The WhatsApp Coexistence API Solution, introduced by Meta, allows businesses to connect their existing WhatsApp Business App number to a Cloud API platform (such as Wati or similar solutions) without disabling the mobile app and without losing chat history.

In simple terms:
You can
✔ Continue chatting 1:1 on the WhatsApp Business App
✔ Use the WhatsApp Cloud API for automation, workflows, and broadcasts
✔ Keep the same mobile number
✔ Sync your chats between both platforms

No migration headaches, no restarting conversations, no losing customers mid-way.

Why the WhatsApp Coexistence API Solution Matters

Before Coexistence, businesses had to choose:

WhatsApp Business App

Ideal for small teams and personal conversations—but limited in automation and scale.

WhatsApp Cloud API

Great for automation, campaigns, integrations, and multi-agent support—but enabling it previously disabled your Business App.

This caused pain points like:
– Losing chat history
– Inability to start new conversations
– Interruption in daily operations

With the Coexistence API, you no longer need to choose.
You get the freedom to scale automation with the API while maintaining everyday 1:1 chats on the mobile app.

Who Should Use the WhatsApp Coexistence API Solution?

1. Sales teams using CRM or shared inbox tools

Coex supports real-time syncing, making it ideal for teams working on leads and follow-ups.

2. Businesses selling high-value or consultative products

Your team can continue personal conversations on the mobile app while running API-based follow-ups and reminders.

3. SMBs upgrading to automation

Perfect for businesses moving to advanced tools like Wati or Whatsboost without losing old conversations.

4. Brands running campaigns and broadcasts

Use the Business App for personal chats and the API for wide-scale messaging.

What You Can Do With WhatsApp Coexistence

✔ Send broadcasts to 250+ contacts

Using the Cloud API interface from tools like Wati or Whatsboost.

✔ Keep your full message history

Up to 6 months of past chats can be synced.

✔ Continue 1:1 chats in the WhatsApp Business App

No functional change except a few feature deprecations.

✔ Sync contacts and chat activity

Contacts sync one-way; 1:1 chats sync two-way.

Group chats stay on the Business App (not synced to API).
