WhatsApp Business API pricing explained
Understand conversation-based pricing and how costs are calculated.
WhatsApp Business API uses conversation-based pricing set by Meta. A conversation is a 24-hour messaging window between your business and a customer.
Conversation categories
Meta defines four categories: Utility (order updates, account alerts), Authentication (OTP messages), Marketing (promotions, offers), and Service (customer-initiated support). Each category has different per-conversation rates that vary by country.
Who bills you for conversations
Meta bills conversation charges to your own WhatsApp Business Account, using the payment method you add in WhatsApp Manager. The money goes from you to Meta directly — SendBlix never resells messages and adds no margin to Meta's rates.
SendBlix platform fee
SendBlix charges a platform subscription fee, and that is the only thing SendBlix charges you for. Your total cost is the SendBlix plan fee plus whatever Meta bills you for conversations.
Adding a payment method at Meta
Open Meta Business Suite > Billing & payments > Accounts (business.facebook.com/latest/billing_hub/accounts), pick your WhatsApp Business account and click Add payment method. Meta refuses to send template messages until a usable payment method is on file, so do this before your first campaign. SendBlix warns you on the dashboard if Meta is blocking sends for this reason.
