Blendlix Call Service Developer Docs
Blendlix Call Service enables secure one-to-one audio calling inside web and mobile applications.
Applications request a short-lived call token from their backend, connect to the realtime WebSocket endpoint, and use WebRTC for audio.
What you will build
An integration has three parts:
| Layer | Responsibility |
|---|---|
| Application backend | Checks application permissions and requests a call session token |
| Blendlix Call Service | Handles session tokens, WebSocket signaling, call state, and ICE server details |
| Client application | Connects to WebSocket, captures microphone audio, and creates the WebRTC peer connection |
Public integration scope
- Audio only
- One-to-one calls
- WebRTC signaling over WebSocket
- Product-authenticated session token API
- Browser and mobile client support
- Phone-call fallback recommended
