The single most important pricing idea on WhatsApp is the message category. Every message you start is marketing, utility or authentication — and Meta charges a different rate for each. Get the category right and you control your bill.
Guides in this section:
- Marketing vs utility vs authentication — the overview, with real examples and prices.
- Marketing messages — onboarding and how to send promotions correctly.
- Marketing messages: errors & languages — common send errors and supported language codes.
- Utility messages — order updates, reminders and other transactional messages.
- Authentication messages — OTPs and login codes.
- One-tap autofill — the OTP button that fills the code automatically.
- Zero-tap — OTP delivery with no taps at all.
- Copy code — the simple copy-the-code authentication format.
