WhatsApp connection: QR code and official API
QR Code or Meta's official API: how each one works, when to choose each, and what protects your number from restriction.

The difference in one line. The QR Code connects in minutes and you do it yourself; the official API is the channel Meta maintains for businesses, more stable for volume, and our team makes the connection with you. In both, your team answers in the same inbox, the same way.
1. The two ways to connect#
| QR Code | Meta official API | |
|---|---|---|
| How it works | The number becomes a linked device, the same mechanism as WhatsApp Web | The number talks to the platform through the channel Meta maintains for businesses |
| Who connects | You, in minutes, by scanning the code on your phone | Our team, together with you, because Meta requires accounts and verifications on its side |
| Phone | WhatsApp must remain installed and active on the number's phone | Does not depend on a phone being on |
| Business-initiated message | Free text, subject to WhatsApp's rules and evaluation | Outside the 24-hour window since the customer's last message, only with a message template approved by Meta |
| Risk of restriction | Low in normal service; rises sharply with mass sending without consent | Lower, as long as Meta's rules are followed |
| Meta costs | None | Meta charges for certain message templates, according to its price table; we agree on this at connection |
| Available | On all plans | On all plans |
2. When to choose each#
Start with the QR Code if
you want to start today, mostly serve people who contact your company, and the volume of messages you initiate is small.
Go with the official API if
the number is critical to the business, you send reminders and notices in volume, or you cannot risk the number being restricted.
3. Who decides on a restriction or block#
WhatsApp, not atendIA. It may restrict or ban numbers that it judges to be outside its policies, in both connection methods, and atendIA has no way to reverse that decision. When it happens, our team helps you understand the likely reason and request a review through WhatsApp's own channels. That is why the Acceptable Use Policy is strict about sending without consent.
4. Best practices that protect your number#
- Send messages only to people who gave you their number to talk to you, and say right away who is speaking.
- Honor opt-outs immediately. Blocks and reports from recipients weigh most heavily against a number.
- Avoid sending the same message, at the same time, to many people who have never talked to you.
- On a new number, start by serving people who contact you, before any outbound sending.
- With the QR Code, open WhatsApp on the number's phone from time to time: if it goes 14 days without use, WhatsApp disconnects linked devices.
- On the official API, maintain template quality: a template that receives many blocks is paused by Meta.
More details in the guide how to avoid being blocked on WhatsApp.
5. Switching from QR Code to the official API#
It is possible. Because the migration touches the number's registration with Meta, our team first explains what changes in the phone app and in the inbox, and schedules the switch with you. Ask through WhatsApp or at [email protected].
6. Instagram, Messenger, and Gmail#
They follow the same principle as the official API: they are connected through each company's official channels, with our team alongside you, and the messages land in the same inbox. What each connection requires is in Requirements.
