  • •Max 1 phone + 4 linked, and only 1 number per app.
  • •256 contacts per broadcast list, and they must have you saved to receive it.
  • •No advanced automation and no API calls.
  • •If you get reported as spam you get a temporary block.
API limitations
  • •Requires Meta approval and business verification.
  • •Cost per conversation: a 24h window charged by type (marketing, service...).
  • •No calls or groups from the API. You need a BSP or your own build.
  • •You cannot see chats in the normal app, only in your dashboard.
In common
  • •No unlimited bots in the app. Spam reports and blocks still apply.
  • •E2E encryption, but Meta sees company metadata (who talks to whom, when).
  • •You cannot have two accounts with the same number. Migrating app to API wipes the history.
  • •Marketing requires explicit opt-in.
SO WHICH ONE DO I PICK?

A quick rule, no sales pitch

If you sell while answering chats yourself or with two or three people, stay on the app. If you need 5+ agents, bots, a CRM and metrics, move to the API even if you pay per conversation. Do not try to automate the app with hacks, you get blocked.

24h API window: you can reply free within itTemplates must be approved by MetaOpt-in is mandatory for promos
