What it is
WhatsApp Business API: what it is and what it is for
The WhatsApp Business Platform (Cloud API) is Meta's official way to integrate WhatsApp directly into business systems — with no need for an intermediary provider (a BSP). It works through approved template messages and per-conversation billing, inside a service window.
How it works
3 traits of the official API
Not for posting third-party Stories/Status
There is no open API for that — it is a communication channel, not a public-content publishing one.
Per-conversation billing, with approved templates
Every message follows a template pre-approved by Meta, inside a 24-hour service window.
Webhooks report message status
Delivered, read, failed — the system receives that confirmation in real time.
Where VitrinaFlow fits in
Post approval, straight on your WhatsApp
VitrinaFlow uses the WhatsApp Business Platform (Cloud API), directly through Meta, for exactly this: notifying you about posts waiting for approval, sending a daily reminder up to the publish date, and summarizing results — with no intermediary provider involved.
