How does WhatsApp charge for the Business API?

WhatsApp charges per conversation, not per individual message. A conversation encompasses all messages delivered in a 24-hour session. Conversations are categorized into Marketing, Utility, Authentication, and Service, each with different pricing based on the recipient's country code.

What are Service conversations?

Service conversations are user-initiated. When a customer messages you, a 24-hour window opens where you can reply with free-form messages. Meta currently does not charge for these inbound service conversations.

Understanding WhatsApp API Pricing

Unlike traditional SMS where you pay per message segment, the WhatsApp Business API operates on a conversation-based pricing model. A conversation includes all messages exchanged within a 24-hour session.

Marketing Conversations
Promotions, offers, informative updates, or invitations. Any conversation that isn't strictly utility or authentication falls here. These carry the highest cost per conversation.
Utility Conversations
Specific, agreed-upon updates related to a transaction. E.g., post-purchase notifications, shipping alerts, or billing statements.
Authentication Conversations
One-time passwords (OTPs) required for login or account verification. These are usually the cheapest business-initiated category.

Tips to Reduce Costs

To optimize your WhatsApp spending, ensure you use the correct message templates. Don't use a marketing template if you only need to send a utility notification, as it will cost more. Additionally, responding to customer service inquiries (inbound messages) is completely free within the 24-hour customer service window, so encouraging users to message you first can reduce outbound costs.
