When this matters
Choosing the right channel type affects:- Message deliverability and sending speed limits.
- Risk of phone number suspension by Meta.
- Cost structure (Meta conversation charges vs. flat-rate unofficial hosting).
- Supported interactive components (like lists and templates).
Key differences
| Feature | Official Channels (Meta Cloud API) | Unofficial Channels (Web/QR) |
|---|---|---|
| Meta Approved | Yes, official API partnership. | No, web session emulation. |
| Suspension Risk | Very low (if compliant with policy). | High (if used for cold outreach/spam). |
| Message Templates | Required for business-initiated chats. | Optional (can send free-form at any time). |
| Sending Limits | Scalable up to unlimited messages/day. | Limited by WhatsApp Web rate limiting. |
| Pricing | Pay-per-conversation (Meta fees apply). | Flat monthly/channel fee (no Meta fees). |
Recommendation
- Use Official Channels for production notification systems, high-volume transactional messages (OTPs, receipt notifications), and customer service teams.
- Use Unofficial Channels for internal testing, staging environments, low-volume alerts, or rapid prototyping where Meta setup overhead is not desired.
