Developers
Build on the
signal.
Everything the dashboard does, your code can do. The API reference, keys, calls, webhooks, and a drop-in widget — all wired to the same infrastructure your campaigns run on.
API documentation
The full REST reference — authentication, campaign configuration, lead management, and every status code, with copy-ready request and response examples.
API keys
Generate, reveal, and revoke the keys that authenticate every API request. Keys are shown in full only at creation — store them somewhere safe.
Test calls
Run a live browser test call against any campaign before it touches real leads. Mic in, agent audio out — the full wire contract at 16 kHz PCM16.
Webhooks
Subscribe to call events — transcript ready, call ended, outcome recorded — and stream them straight into your own systems.
Widget embed
Drop the Vaanii widget into any site with one script tag. It handles mic capture, streaming, and reconnects so you don't have to.
