A few calls to a call

Start a voice or video call from the SDK

Authenticate your user, create or join a room, and start audio or video. The same room can carry chat messages alongside the call.

call.js

const chat = new EthoraChat({ apiUrl: YOUR_HOST, appId: YOUR_APP_ID });
await chat.login(userToken);

const room = await chat.rooms.create({ name: "Consult - Jane D." });

// start a call in the room
await room.calls.start({ audio: true, video: true });

Illustrative. Voice, video, and chat share the same room and SDK across web, iOS, Android, and React Native.

Voice & video call API FAQ

What is a voice and video call API?

It is a developer API and SDK that adds real-time audio and video calling to your app, usually over WebRTC, so you do not have to build signalling, media servers, and cross-platform clients yourself.

Does Ethora use WebRTC?

Yes. Ethora's calling is WebRTC-based for low-latency one-to-one and group audio and video, with cross-platform SDKs for web, iOS, Android, and React Native.

Can I have voice, video, and chat together?

Yes. Calls and messaging share the same room and SDK, so you can add in-call chat and file sharing, or escalate a chat to a call, without a second vendor.

Can I self-host the calling infrastructure?

Yes. You can run the media stack on your own cloud or on-premises so call media and metadata stay in the environment you control.

Which platforms are supported?

Web (React), iOS (Swift), Android (Kotlin), and React Native, from one backend.
