Cost

Meta charges per session, not aper individual message. A session is 24-hour message threads between you and your customers.

A session is said to have started, when a user sends a message to your WABA, or the business sends an outbound message to its contact.

Outbound messages are categorised into four categories:

• Marketing: Enables you to achieve a wide range of goals, from generating awareness to driving sales and retargeting customers. Examples include new product, service, or feature announcements, targeted promotions/offers, and cart abandonment reminders.

• Utility: Enables you to follow up on user actions or requests. Examples include opt-in confirmation, order/delivery management (e.g., delivery update); account updates or alerts (e.g., payment reminder); or feedback surveys.

• Authentication: Enables you authenticate users with one-time passcodes, potentially at multiple steps in the login process (e.g., account verification, account recovery, integrity challenges).

• Service: Enables you to resolve customer inquiries.

Each month you will get 1,000 free service conversations all of its business phone numbers. This number is refreshed at the beginning of each month, based on WhatsApp Business Account time zone.

Marketing, utility and authentication conversations are not part of the free tier.
