## Personal vs WhatsApp Business API

*Comparison*

Both options work fully in HAPP — the difference is how you connect and what Meta restricts.

- **Fastest path to a live channel** — Any number, personal or business. No Meta Business account, no templates, no 24-hour window. Connect via QR or code in under a minute.
- **Built to scale** — Official Meta API, not tied to a smartphone, verified business number, thousands of messages a day — at the cost of Meta onboarding.
- **Your phone stays in the loop** — The personal route uses the unofficial multi-device protocol, so the phone must come online at least every 14 days.
- **Live session status** — HAPP shows whether the connection is active and messages are arriving — without a page reload.
- **Same inbox as everything else** — The personal number lands in the shared feed with your other channels and assistants.

## Frequently asked questions

*FAQ*

Answers to the most common questions about connecting a personal WhatsApp number.

### What is the difference between QR and pairing code connection?

The QR code is scanned with the phone camera via WhatsApp → Linked Devices. The pairing code is an 8-digit numeric code entered in the same menu without a camera. Both methods give the same result.

### Does the smartphone need to be online at all times?

HAPP uses WhatsApp Multi-Device, so the smartphone doesn't need to be online constantly. However, if the phone is offline for more than 14 days, WhatsApp will end the session and you'll need to reconnect.

### When should I choose Business API over personal connection?

Business API is better if you need a verified business number, scaling to thousands of messages per day, or sending outbound messages via templates. Personal connection is for a fast start without a Meta Business account.

### Can I connect multiple WhatsApp numbers?

Yes. Each number connects separately via its own QR code and creates its own channel in HAPP with its own assistant or operator team.

### Is QR code connection secure?

Yes. The connection uses WhatsApp's standard Linked Devices mechanism — the same one used by WhatsApp Web. HAPP does not store passwords or share data with third parties.

### What happens to messages if HAPP is temporarily unavailable?

WhatsApp keeps messages on its servers. When HAPP reconnects — all missed messages will be synced and processed automatically.

### Can customers tell an AI is replying?

The customer sees a message from your regular WhatsApp number — name and avatar remain yours. You're free to mention or not mention that it's an AI assistant.

## Ready in under a minute?

Scan one QR code and your existing WhatsApp number starts answering — no Meta Business account required.
