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

To connect ConnectyCube to your iOS app just add it into your Podfile which is a part of CocoaPods tool:

platform :ios, '9.0'
use_frameworks!


target 'MyApp' do
  pod 'ConnectyCube'
end

and then install packages from the command line:

Terminal window
pod install

Import SDK

Add the following import statement to start using all classes and methods.

import ConnectyCube

Initialize SDK

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

ConnectyCube().doInit(applicationId: APP_ID, authorizationKey: AUTH_KEY, authorizationSecret: AUTH_SECRET, connectycubeConfig: nil)

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({ session -> }, { error -> })

Register a user

let user: ConnectycubeUser = ConnectycubeUser()
user.login = "marvin18"
user.password = "supersecurepwd"
user.email = "awesomeman@gmail.com"
user.fullName = "Marvin Simon"
user.phone = "47802323143"
user.website = "https://dozensofdreams.com"
user.tags = "iphone, apple"


ConnectyCube().signUp(user: user, successCallback: {(user) in


}) { (error) in


}

Create 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:

ConnectyCube().signIn(user: userToLogin, successCallback: {(user) in


}) { (error) in


}

Now that the user is authorized in the application, they can proceed with chat creation, messaging, voice and video calls 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:

let user = ConnectycubeUser()
user.id = 2746
user.password = "supersecurepwd"


ConnectyCube().chat.login(user: user, successCallback:{


}, errorCallback: { error in


}, resource: ConnectycubeSettings().chatDefaultResource)

Step 4: P2P calls initialization

Before any interaction with ConnectyCubeCalls you need to initialize it:

ConnectyCube().p2pCalls.register()

Step 5: Initiate call

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

let opponentsIds = [3245, 2123, 3122].map{KotlinInt(value: $0)}
let newSession = ConnectyCube().p2pCalls.createSession(userIds: opponentsIds, callType: CallType.video)
// userInfo - the custom user information dictionary for the call. May be nil.
let userInfo = ["key":"value"] as? KotlinMutableDictionary<NSString, NSString> // optional
newSession.startCall(userInfo: userInfo)

After this your opponents will receive one call request per 5 second for a duration of 45 seconds (you can configure these settings with WebRTCConfig:

//MARK: RTCCallSessionCallback
ConnectyCube().p2pCalls.addSessionCallbacksListener(callback: self)


extension YourClass: RTCCallSessionCallback {
    func onReceiveNewSession(session: P2PSession) {
        if self.session != nil {
            // we already have a video/audio call session, so we reject another one
            // userInfo - the custom user information dictionary for the call from caller. May be nil.
            let userInfo = ["key":"value"] as? KotlinMutableDictionary<NSString, NSString> // optional
            session.rejectCall(userInfo: userInfo)
            return
        }
        // saving session instance here
        self.session = session
    }
...
}

self.session refers to the current session. Each particular audio - video call has a unique sessionID. This allows you to have more than one independent audio-video conferences. If you want to increase the call timeout, e.g. set to 60 seconds:

WebRTCConfig().answerTimeInterval = 60

Default value is 60 seconds.

In case opponent did not respond to your call within a specific timeout time, the callback listed below will be called:

//MARK: RTCCallSessionCallback
ConnectyCube().p2pCalls.addSessionCallbacksListener(callback: self)


func onUserNotAnswer(session: P2PSession, opponentId: Int32) {


}

Step 6: Accept a call

In order to accept a call, use the P2PSession method below:

// userInfo - the custom user information dictionary for the accept call. May be nil.
let userInfo: KotlinMutableDictionary<NSString, NSString> = ["key":"value"] // optional
self.session?.acceptCall(userInfo: userInfo)

After this you will receive an accept signal:

//MARK: RTCCallSessionCallback
ConnectyCube().p2pCalls.addSessionCallbacksListener(callback: self)


func onCallAcceptByUser(session: P2PSession, opponentId: Int32, userInfo: [String : Any]?) {


}

Great work! You’ve completed the essentials of making a call in ConnectyCube. From this point, you and your opponents should start seeing and hearing each other.
