The WhatsApp Business API is the only official way to send automated messages at scale. But Meta's pricing model is confusing. Conversations, sessions, utility messages, marketing messages — what does it all cost? We have sent 500,000+ messages through the API. Here is the breakdown.

Utility 0.015 Euro 0.004 USD Transactional (receipts, alerts)

Authentication 0.010 Euro 0.003 USD OTP, login codes

Marketing 0.050 Euro 0.013 USD Promotional messages
