Simple, per WhatsApp number
Fee per connected number. Message costs go straight from the platform to you. We never mark them up.
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.
See all
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. The price per number falls as the count rises: from US$ 9 each up to five numbers, falling to US$ 0.75 each as you add numbers, so ten numbers is US$ 70 rather than US$ 90. Your first 3 days are free.
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?
Sixteen 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, search the docs, and start a new connection, plus five that set up the Partner API so your own customers can connect numbers through hosted connect links.
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.
