Availability. Web Callback works with a sandbox key today.
Voice (virtual numbers, queues) and
recordings use a production key (
sk_live_) — ask your Wave contact to enable
them. WhatsApp messaging is on the roadmap.Get started
Quickstart
Get a sandbox key and place your first callback in under 5 minutes.
How voice works
Numbers, call flows, and events — the shape of a Wave call.
Authentication
How API keys work and how to send them.
API Reference
Every endpoint, with an interactive playground.
What you can build
Web Callback
Click-to-call from your backend — Wave dials and bridges the call.
Virtual numbers
A Saudi number for every end-user, with their own greeting.
Queues
Route callers to agents and manage who’s logged in.
WaveML
The verbs a call flow speaks — Wave’s answer to TwiML.
Every response uses Wave’s standard error envelope
(
error_code + bilingual message / message_ar), and endpoints are
rate-limited per key.
