Developers
A real WhatsApp Business API, built for automation.
Scoped API keys, predictable JSON, and webhooks for the events that matter — messages, contacts, conversations, broadcasts and segments.

Authenticate with a scoped key
Create a key in Settings → API keys, scope it to what it needs, and send it as a bearer token. Keys are encrypted at rest and never shown again after creation.
Authorization: Bearer sk_live_••••••••••••
Send a WhatsApp template
One POST sends an approved template with per-recipient variables. Delivery and read status flow back via webhooks.
