Make first call

ConnectyCube Video Calling Peer-to-Peer (P2P) API provides a solution for integrating real-time video and audio calling into your application. This API enables you to create smooth one-on-one and group video calls, supporting a wide range of use cases like virtual meetings, telemedicine consultations, social interactions, and more. The P2P approach ensures that media streams are transferred directly between users whenever possible, minimizing latency and delivering high-quality audio and video.

If you’re planning to build a new app, we recommend starting with one of our code samples apps as a foundation for your client app.
If you already have an app and you are looking to add chat and voice/video calls to it, proceed with this guide. This guide walks you through installing the ConnectyCube SDK in your app, configure it and then initiating the call to the opponent.

Before you start

Before you start, make sure:

  1. You have access to ConnectyCube account. If you don’t have an account, sign up here.
  2. An app created in ConnectyCube dashboard. Once logged into your ConnectyCube account, create a new application and make a note of the app credentials (app ID, auth key, and auth secret) that you’ll need for authentication.

Step 1: Configure SDK

To use chat in a client app, you should install, import and configure ConnectyCube SDK.

Note: If the app is already created during the onboarding process and you followed all the instructions, you can skip the ‘Configure SDK’ step and start with Create and Authorise User.

Install SDK

Сonnect SDK js file as a normal script:

<script src="https://cdn.jsdelivr.net/npm/connectycube/dist/connectycube.min.js"></script>

Initialize SDK

Initialize the SDK with your ConnectyCube application credentials. You can access your application credentials in ConnectyCube Dashboard:

const CREDENTIALS = {
appId: 21,
authKey: 'hhf87hfushuiwef',
authSecret: 'jjsdf898hfsdfk',
};
ConnectyCube.init(CREDENTIALS);

Step 2: Create and Authorise User

To make API requests, firstly you need to create and authenticate a user who will initiate a call later.

Create an application session

ConnectyCube.createSession()
.then((session) => {})
.catch((error) => {});

Register a user

const userProfile = {
login: "marvin18",
password: "supersecurepwd",
email: "awesomeman@gmail.com",
full_name: "Marvin Simon",
phone: "47802323143",
website: "https://dozensofdreams.com",
tag_list: ["iphone", "apple"],
custom_data: JSON.stringify({ middle_name: "Bartoleo" }),
};
ConnectyCube.users
.signup(userProfile)
.then((user) => {})
.catch((error) => {});

Create a user’s session

To allow users to proceed with any actions within the application, you need to create a session for them. Having created an application session, you need to upgrade it to a user session by calling login method:

const userCredentials = { login: "marvin18", password: "supersecurepwd" };
// const userCredentials = { email: 'awesomeman@gmail.com', password: 'supersecurepwd' };
// const userCredentials = { provider: 'facebook', keys: {token: 'a876as7db...asg34dasd8wqe'} };
ConnectyCube.login(userCredentials)
.then((user) => {})
.catch((error) => {});

Now that the user is authorized in the application, they can proceed with chat creation and messaging with opponent(s).

Step 3: Connect User to chat

Connecting to the chat is an essential step in enabling real-time communication.

To start using Video Calling API you need to connect user to Chat as ConnectyCube Chat API is used as a signalling transport for Video Calling API:

const userCredentials = {
userId: 4448514,
password: "supersecurepwd",
};
ConnectyCube.chat
.connect(userCredentials)
.then(() => {
// connected
})
.catch((error) => {});

Step 4: Connect WebRTC lib

For Android - there is nothing extra required. Android Cordova WebView supports all the WebRTC API stack.

For iOS - a cordova-plugin-iosrtc has to be used.

Step 5: Create video session

In order to use Video Calling API you need to create a call session object - choose your opponents with whom you will have a call and a type of session (VIDEO or AUDIO):

const calleesIds = [56, 76, 34]; // User's ids
const sessionType = ConnectyCube.videochat.CallType.VIDEO; // AUDIO is also possible
const additionalOptions = {};
const session = ConnectyCube.videochat.createNewSession(calleesIds, sessionType, additionalOptions);

Step 6: Access local media stream

To have a video chat session you need to get an access to the user’s devices (webcam / microphone):

const mediaParams = {
audio: true,
video: true
};
session
.getUserMedia(mediaParams)
.then((localStream) => {
// display local stream
session.attachMediaStream("myVideoElementId", localStream, {
muted: true,
mirror: true,
});
})
.catch((error) => {});

This method lets the browser ask the user for permission to use devices. You should allow this dialog to access the stream. Otherwise, the browser can’t obtain access and will throw an error for getUserMedia callback function.

For more information about possible audio/video constraints, here is a good code sample from WebRTC team how to work with getUserMedia constraints: https://webrtc.github.io/samples/src/content/getusermedia/resolution/

Step 7: Initiate call

Initiate Call function sets up the foundational connection between the caller and the selected opponents:

const extension = {};
session.call(extension, (error) => {});

The extension is used to pass any extra parameters in the request to your opponents.

After this, your opponents will receive a callback call:

ConnectyCube.videochat.onCallListener = function (session, extension) {};

Or if your opponents are offline or did not answer the call request:

ConnectyCube.videochat.onUserNotAnswerListener = function (session, userId) {};

Step 8: Accept a call

To accept a call the following code snippet is used:

ConnectyCube.videochat.onCallListener = function (session, extension) {
// Here we need to show a dialog with 2 buttons - Accept & Reject.
// By accepting -> run the following code:
//
// 1. await session.getUserMedia (...)
//
// 2. Accept call request:
const extension = {};
session.accept(extension);
};

After this, you will get a confirmation in the following callback:

ConnectyCube.videochat.onAcceptCallListener = function (session, userId, extension) {};

Also, both the caller and opponents will get a special callback with the remote stream:

ConnectyCube.videochat.onRemoteStreamListener = function (session, userID, remoteStream) {
// attach the remote stream to DOM element
session.attachMediaStream("remoteOpponentVideoElementId", remoteStream);
};

From this point, you and your opponents should start seeing and hearing each other.
