WhatsApp Business API pricing confuses a lot of businesses because it isn't "per message" — it's "per conversation." Here's the simple version.
Conversation-based pricing
Meta charges per 24-hour conversation, not per message. Once a conversation opens, all messages within that 24-hour window are covered by a single charge. Rates depend on the conversation category.
The four categories
Marketing (offers, promotions) is the priciest. Utility (order updates, reminders) and Authentication (OTPs) are cheaper. Service conversations (customer-initiated support) are often free within limits. Exact rates vary by country and Meta's current pricing.
What else is in the cost?
On top of Meta's conversation fees, your BSP (Business Solution Provider) charges a platform fee for the API, dashboard, chatbot, team inbox and support. A transparent provider shows both clearly.
How to estimate your monthly cost
Estimate the number of marketing, utility and authentication conversations you'll start each month, multiply by the per-conversation rate for each category, and add the platform fee. We can build this estimate with you in minutes.
