WhatsApp API pricing: per-message billing changed the maths in 2025
Meta moved WhatsApp Business API billing from a per-24-hour-conversation model to per-message billing on 1 July 2025 — every marketing, utility and authentication template you send is now charged individually rather than bundled into a single conversation-window fee, which materially changes the economics for high-volume marketing sends specifically.
Malaysia rates run roughly RM0.3467 per marketing message and RM0.0564 per utility or domestic authentication message, with Meta billing Malaysia directly in MYR since April 2026 rather than requiring a USD conversion.
