Glossary

Terms worth
knowing.

WhatsApp Business Platform
Meta's official way for businesses to message at scale over the WhatsApp Cloud API, separate from the free WhatsApp Business app.

Phone number ID
The identifier Meta gives each registered WhatsApp number, used when you send through the API.
BSP
Business Solution Provider. A company that helps businesses onto the WhatsApp Business Platform. WBIZ connects you through Meta's own signup.
Message template

Opt-in
