Meta released a note stating that as of October 1st, every message sent through the official API will be charged, that is, there will no longer be a 24-hour window (except for leads coming through an advertisement in the click to WhatsApp format). This will make it too impossible to use WhatsApp on GHL via the official API, because with every message being charged, the cost per conversation will be very high. Even the answers given by I.A will be charged by META. It would be impossible, especially for the Brazilian public, to maintain such a cost.
