Your team answers on the phone, your agent answers on the API, and both see the same thread.
One WhatsApp number, two channels.
Coexistence is Meta's official feature: the WhatsApp Business app and the Cloud API working on one number at the same time. Not a workaround, not an unofficial gateway.
Your team keeps answering in the WhatsApp Business app. The same number gains an official API your system can send and receive on.
Live in three steps
No migration. No lost chats.
Create your account
Name, email, password. Thirty seconds.
Connect your number
Scan a code from the app you already use. It keeps working exactly as before.
Point it at your system
Paste your webhook URL, or add the connector to Claude or ChatGPT. Messages arrive immediately.
Nothing charged for 7 days. Cancel anytime.
Your AI already knows how to use it.
Add one connector. Claude, ChatGPT, Cursor and Claude Code can then list your numbers, send messages and templates, check health and point the webhook at your own system.
https://easycoexistence.com/api/mcpOfficial Cloud API, over OAuth. Every other WhatsApp MCP server drives WhatsApp Web as a linked device, which is what gets numbers banned.
Both worlds. No trade-off.
The number your customers already message, doing everything a Cloud API number does, without leaving the phone your team answers on.
An MCP server for your AI
Add one connector to Claude, ChatGPT or Cursor and just ask: send messages, create templates, check health, point the webhook at your system.
The phone stays the phone
Your team opens the app and replies as always. No new panel, nobody to retrain.
The Cloud API on the same number
Your system, your n8n, your CRM or your AI send and receive through the number your customers already know.
Your history stays put
No migration, nothing to export. Conversations stay on the device, exactly as they are.
Drop detection
The moment a connection breaks, even from 14-day inactivity, we catch it and show the reason.
A bridge, not a cage
Messages route straight to your system. We never store conversations, and you are never locked into anyone's inbox.
We watch the WhatsApp connection so you do not have to.
Quality, tier and connection state, checked around the clock. If the link drops, you see it first, with the reason and the fix.
Built for the people building on WhatsApp.
AI agent builders
Your assistant needs a real number, not a throwaway that gets banned.
Automation agencies
One account, every client's number. Add and remove them as clients come and go.
Product teams
Your app needs messaging. You do not want to run a gateway or migrate anyone's number.
Nothing charged for 7 days. Cancel anytime.
Simple, per WhatsApp number
Flat fee per connected number. Message costs go straight from the platform to you. We never mark them up.
- Guided Coexistence onboarding
- 24/7 health & connection monitoring
- Instant disconnection detection

Cancel anytime during the trial and you are charged nothing. Meta bills its own messaging costs directly to you.
Questions, answered
Will I lose my chat history?
No. Coexistence connects your existing number without a migration, so your conversations stay intact.
Does my business app keep working?
Yes. You keep using the app exactly as before; the API connection runs alongside it.
Do I lose my groups?
No. Groups keep working normally in the app and your team chats in them as always. What you do not get is groups through the API: it neither sends nor receives group messages, so your automation cannot see them.
What about catalog, orders, payments and calls?
They all stay on the phone, unchanged. They simply sit outside the API, so your system cannot automate those parts.
What exactly gets disabled in the app?
Disappearing messages, view once and live location stop working in one-to-one chats. Existing broadcast lists become read-only and you cannot create new ones. Templates can only be sent through the API from then on. Onboarding also unlinks the Windows and WearOS companions, and supported devices can be linked again afterwards.
How fast can the API send?
20 messages per second. That is a fixed ceiling the platform applies to coexistence numbers, so it is not something we or you can raise.
Can I undo it?
Yes. You can disconnect the number from the API whenever you want and carry on with the app alone. The conversations were always on the phone, and they stay there.
Is there a limit on how many numbers I can connect?
No limit. Connect as many as you need from a single account, at US$9 per number per month, so five numbers is US$45. Your first 7 days are free, and you can cancel during the trial without being charged.
Who pays for the messages?
The platform bills conversations directly to you, on your own account's payment method. We never mark them up. Our charge is only the flat monthly fee per connected number.
Do you read my messages?
No. We only use the account and phone-number status needed to monitor your connection's health. We never read or store conversation content.
Can I connect numbers for my clients?
Yes. One account, as many client numbers as you need, each billed as its own connection.
What can the AI connector actually do?
Ten tools: list numbers, check health, read API credentials, send a message, list, create and send templates, check a template's status, point the webhook at your system, and start a new connection.
Can my number get banned because of this?
No. This is the platform's official API through an official feature. The ban risk people talk about comes from unofficial gateways that log in as a linked device.
Which countries does this work in?
Coexistence is available in most of the world, including Brazil, Mexico, the United States, India, Indonesia, Malaysia, the Philippines, Singapore, the UAE, Saudi Arabia, Nigeria, South Africa, Hong Kong and most of Europe. If your number is eligible, our onboarding will say so before anything changes.
