How WhatsApp API Pricing Works in 2026

Meta categorizes WhatsApp Business Platform conversations into 4 distinct types, each billed per delivered message.

1. Marketing Messages

Used for promotions, announcements, discounts, and personalized offers. These carry the highest Meta rate due to exceptional consumer open rates (98%+).

2. Utility Messages

Critical operational messages confirming an ongoing transaction, such as order confirmation, shipping tracking, billing statements, and appointment reminders.

3. Authentication Messages

One-time passcodes (OTPs) and multi-factor authentication codes delivered directly to customers during logins or secure transactions.

4. Service Messages

Free-form customer support responses initiated by the user. Each WhatsApp Business Account gets 1,000 free service messages each month.

ZENChatz offers direct Meta Cloud API connectivity with highly competitive, transparent pricing. Unlike foreign providers that charge in USD with 3.5%–5% currency exchange fees, we provide domestic billing in INR with 100% compliant GST tax invoices, no hidden charges, and dedicated customer support.

No. Incoming messages sent by your customers to your WhatsApp number are 100% free. Charges only apply when your business replies or sends outgoing templates.

When a customer clicks on a Meta Click-to-WhatsApp ad on Facebook or Instagram and starts a chat with your business, Meta provides an extended 72-hour free messaging window where all subsequent service and utility messages are completely free of charge.
