What is WhatsApp Business API?

The WhatsApp Business API (also called WhatsApp Cloud API) is Meta's developer-grade messaging interface for businesses to send and receive WhatsApp messages programmatically through a business solution provider or directly from Meta.

Also called: WhatsApp Cloud API

How it works

Businesses register a WhatsApp Business Account, connect a phone number, and send messages through HTTPS APIs instead of the consumer app alone. Conversation-based pricing applies by category (marketing, utility, authentication, service).

Templates are often required for outbound opens outside the 24-hour customer service window.

Key components

WABA (WhatsApp Business Account), phone number, BSP or Cloud API hosting, message templates, webhooks for inbound events, and opt-in compliance.

Examples

An event brand moves a buyer from Instagram DM to WhatsApp API so voice notes and PDFs continue on the channel closers already use.

A clinic sends appointment reminders as utility messages after the patient messaged first.
