How much does a WhatsApp API message cost?
WhatsApp Business Cloud API rates depend on the message category (Marketing, Utility, Authentication, or Service) and the country code of the recipient’s phone number. Meta bills these charges directly based on delivered messages or 24-hour conversation sessions.
What changes on 1 October 2026?
Starting 1 October 2026, Meta updates its global rate card. Service replies sent by human agents or AI chatbots inside an active 24-hour window, as well as utility templates sent inside an open chat, become billable at the market’s utility rate.
| Becomes Billable on 1 October | Stays Free |
|---|---|
| • Service replies inside 24h window (human or AI) | • Messages customers send to you (Inbound) |
| • Utility templates sent inside open 24h window | • Replies sent from WhatsApp Business App on phone (Coexistence) |
| • High-volume automated customer support conversations | • Messages in 72-hour free entry window from CTWA ads & Facebook Page buttons |
Are AI chatbot replies charged on WhatsApp?
Yes, third-party AI chatbot replies are billed as service messages at Meta’s standard rate card. When an AI chatbot responds to a customer inquiry on the WhatsApp Business API, each reply counts towards your monthly billable volume after your 1,000 free monthly service conversations.
How much more will my business pay?
The financial impact depends on whether your business is Marketing-led or Support-led:
Marketing-Led Businesses
If most of your volume is outbound broadcast campaigns, your costs remain stable since marketing template rates are unchanged.
Support-Led Businesses
If your team or AI handles thousands of inbound support inquiries monthly, your bill will reflect newly billable service replies above the 1,000 free monthly threshold.
How is WhatsApp pricing calculated by country?
Meta calculates charges based on the country code of the customer receiving the message. For instance, sending a marketing message to a phone number in North America carries a different rate card than sending to India or Western Europe.
