How does WhatsApp Business API pricing work?
Meta charges per delivered message, not per conversation. The price depends on the message's category and the recipient's country. Incoming messages from your customers are always free and unlimited.
- Incoming messages from customers (always, no limit)
- Replies within the 24-hour service window (service messages)
- Conversations started from a "click-to-WhatsApp" ad (72-hour window)
- Marketing messages (campaigns, promotions)
- Utility messages (transactional confirmations, notifications)
- Authentication messages (OTP, verification)
- Starting October 1, 2026: service messages too

The 24-hour customer service window
When a customer writes to you, a 24-hour window opens during which you can reply freely. The window resets every time the customer writes again.
Inside the window
You can reply with any message type, no template needed. Free today (service message); billed at the utility rate from October 2026.
Outside the window
You need a Meta-approved template to write to the customer again. Always billed, per its category.
Business-initiated messages
If you write first (without the customer having written before), it always requires a template and is always billed — this doesn't change in October 2026.
