Video Calling API for Your Application

PurpleCallio is a developer-focused video calling API for products that need browser-based calls without assembling signaling, authentication, TURN, and meeting UI independently.

Select a stage to understand the workflow.

1. Create and manage the call from trusted backend code.
2. Issue participant-specific access as part of your application flow.
3. Connect participants through hosted UI, React components, or the headless SDK.
4. Use your product UI to manage media controls and call state.

Create and manage calls through REST APIs, then connect participants with hosted UI or an interface built with the React or headless SDK.

Video calls use WebRTC for browser media. PurpleCallio provides the surrounding call lifecycle, access, signaling, and relay infrastructure.

PurpleCallio supports REST API call management, WebSocket signaling, authentication, TURN relay, camera and microphone controls, device selection, and screen sharing where applicable.

Compare the three integration surfaces, their responsibilities, and a copyable starting point.

import { PurpleCallioClient } from "@purplecallio/sdk";

const client = new PurpleCallioClient({ apiKey: process.env.PURPLECALLIO_API_KEY! });
const call = await client.createCall({ callerId, receiverId });
redirect(call.callerUrl);

Keep API keys on your server and issue only participant-specific access to clients. Webhook requests should be verified before your application processes them. Usage is measured in participant-minutes; see pricing for allowances and current rates.
