What the Official API means in plain terms

Two different “business WhatsApp” paths. Knowing which is which avoids lost sales and number bans.

WhatsApp Business (app)

Phone app with catalog and quick replies. One agent at a time, no Meta-approved bulk sending.

Official Meta API (Cloud API)

WhatsApp Business Platform operated by Radar Chat: multiple agents, automation, AI, integrations and approved templates.

Moving from app to API is not an “upgrade” — they are different paths. Teams that ignore this often learn late, after a ban or during their busiest week.

Questions before migrating

Direct answers about Cloud API, costs and operating on Radar Chat.

The app runs on a phone, one agent at a time. Official Meta API (Cloud API) operates the number via platform — multiple agents, templates, automation and integrations under Meta rules.
Yes. In the same tenant when it makes sense: QR for legacy flows or transition, Cloud API for scale, templates and Meta compliance.
Migrating the number to Cloud API requires planning. App history does not transfer automatically; our team guides the transition in the diagnostic.
Meta charges per delivered message, by template category and recipient country. Service-category support can be free in the window. Use the calculator above as reference.
No. Radar Chat is the panel — Meta connection, Inbox, queues, RadarFlow and AI. Advanced integrations use documented REST API.
