Message templates (HSM)
With the official Meta API, you can create approved templates — proactive messages that reach even users who have never messaged you before. With unofficial APIs, this does not exist. You are limited to responding to whoever contacts you first. For many use cases (notifications, alerts, confirmations), this is a blocker.
The real risk
This is not FUD. This is what happens: Meta tracks usage patterns that indicate automation via WhatsApp Web. When identified, it bans. The number disappears. The history disappears. The client loses communication. It has happened to serious companies, in production, without warning.
When Z-API might make sense
If you have a simple use case, low volume, and a ban would just be an inconvenience — maybe it makes sense. If WhatsApp is a critical channel of your product, it does not.
Official API. No risk. No enterprise bureaucracy.
