WhatsApp Business Platform docs (WABA reference)
Meta‘s first-party developer reference for the WhatsApp Business Platform (Cloud API), organized around the WhatsApp Business Account (WABA). The canonical description of the platform this whole spoke sits on.
What it covers
- Account & auth — WABA setup, access tokens, permissions.
- Phone numbers — business number registration and verification.
- Message types — text, media, interactive (buttons/lists), location, reactions.
- Templates — the marketing / utility / authentication / service template system for business-initiated messages.
- Webhooks — receiving inbound messages and status callbacks.
- Commerce — product catalogs and catalog-sharing.
- Calling & groups — voice calling and group-management surfaces.
- Pricing & billing — conversation-based/template-based charging and billing management.
- Partner program — Tech Providers / Solution Partners and Measurement Partner tiers.
Significance
This documents the permissioned, metered nature of the channel: business messaging is anchored to a WABA, gated by template approval, and priced per conversation/template. Those constraints are what create demand for the SDK (wapi-go) and BSP (business-solution-provider) layers above it.
Tier
T1 — authoritative first-party platform reference. Note that pricing and template-category details are volatile and should be treated as dated snapshots.
