Meta introduces per-message pricing for WhatsApp API, impacting law firms

Meta will charge R$0.035 per message via the official WhatsApp API starting October 1, 2026, with a free tier of 1,000 messages per month per business number. This affects law firms using the channel for consultations and updates, prompting migration to the official API and adoption of AI to reduce message volume. The change represents a shift in Meta's monetization strategy for business messaging, with cost implications for high-volume users.
