Can the official WhatsApp API link any number?
The short answer
No. Meta registers the number and takes it off the app.
What Meta's documentation says
Meta's official WhatsApp Cloud API is built for business messaging: templates, customer-service windows and per-conversation pricing. A large part of what WhatsApp itself can do — groups, channels, status, presence, contact lookups — has no endpoint there at all, which is why so many teams end up looking past it. Everything below is checked against Meta's own published reference, with the link and the date we checked it.
Restricted on the Cloud API
"Registered numbers can still be used for everyday purposes, such as calling and text messages, but cannot be used with WhatsApp Messenger." (verbatim)
Wapito is an independent product. It is not affiliated with, endorsed by, sponsored by or certified by WhatsApp or Meta Platforms, Inc. WhatsApp is a trademark of Meta Platforms, Inc.
Why the Cloud API restricts it
On the official platform a number is registered with Meta rather than paired from a phone, and Meta's own documentation is explicit that a registered number can no longer be used with WhatsApp Messenger. Advanced access generally requires business verification as well, so the number, the onboarding and the ownership are all different in kind.
The official workaround, and what it costs
Register a second, dedicated number with Meta and keep the human-facing one on the phone. That is a real answer for many businesses - it just is not the same thing as automating the number your customers already message.
What the official route costs is not only the per-message price. Every row below is quoted from Meta's own documentation, with a link to the page and the date it was read.
| What it costs | What Meta's documentation says | Source |
|---|---|---|
| Writing to someone first | A business may send free-form messages only inside a 24-hour customer service window that the user opens by messaging or calling. Once the window closes, only pre-approved template messages may be sent. | Meta's docs checked |
| Every message you send | Meta charges for the WhatsApp Business Platform per message rather than per conversation. The earlier per-conversation model was replaced on 1 July 2025, so any comparison written before that date is out of date; free entry point windows remain an exception. | Meta's docs checked |
| Getting onto the platform | Apps that need advanced access to Meta's permissions may have to complete Business Verification, a process in which Meta collects information to verify the business entity. It is a real onboarding step with a real elapsed time, and it has no equivalent when you link a number you already own. | Meta's docs checked |

You need a verified business identity
The official platform is the only route to an Official Business Account: the verified name customers see in place of a phone number, and the badge beside it. A linked number can carry a WhatsApp Business profile, but Meta will never badge it, and no provider can get you one.
You are sending marketing at scale to people who never wrote to you
That is what approved templates are for. Meta charges per message for them and treats the volume as legitimate; the same volume from a linked number is the clearest automation signal there is, and it is how numbers get banned. If outbound campaigns are the whole product, the official platform is the cheaper mistake.
You need Meta's own support and an SLA
A Business Solution Provider gives you a contract, an escalation path and a human to call when delivery stops. Wapito will tell you the moment WhatsApp restricts your number and what it did; nobody outside Meta can make it undo that, and we do not pretend otherwise.
Frequently asked questions
Should I use a pairing code or a QR?
A pairing code, in almost every case. It can be read aloud, pasted into a chat or typed from a support ticket, and it does not depend on a camera pointed at a refreshing image. QR linking of new devices has also been unreliable across engine libraries since mid-2026, so treat it as the fallback.
Can I keep using WhatsApp on the phone afterwards?
Yes - that is the central difference from the official platform. Wapito links a companion device, exactly like WhatsApp Web, so the human keeps their app, their chats and their history while your automation works alongside them on the same number.
What happens if the session drops?
The channel webhook fires with the new state, the previous state and a reason. A transient engine restart reconnects by itself; a logout by the phone's owner or a ban does not, and both need a person. Branch on the reason rather than retrying blindly into a session that is gone.
