In order to use the features of the Calls SDK in your client apps, user authentication with Sendbird server must be initiated through the
SendBirdCall.authenticate() method. To make or receive calls, the
SendBirdCall instance should be connected with Sendbird server. Connect socket by using the
SendBirdCall.connectWebSocket() method after a user’s authentication has been completed.
Note: Even if your organization already uses Sendbird Chat, a separate user authentication is needed for Sendbird Calls.
As shown below, the
SendBirdCall instance must be initialized when a client app is launched. Initialization is done by using the
APP_ID of your Sendbird application in the Dashboard. If the instance is initialized with a different
APP_ID, all existing call-related data in a client app will be cleared and the
SendBirdCall instance will be initialized again with the new
In order to use the interfaces and methods provided in a
SendBirdCall instance, a user must be connected to Sendbird server by authentication. Without authentication, calling the methods of the Calls SDK will not work in a user’s client app. This means that if a user performs actions such as accepting an incoming call before authentication, the user will receive errors from Sendbird server.
Note: Sendbird Calls is charged by minutes which starts as soon as the call is connected. It is recommended that you authenticate users for the Calls SDK at your earliest convenience.
Deauthenticate a user from Sendbird server using the
SendBirdCall.deauthenticate() method. It will clear all current direct calls, session keys, and user information from a user’s client app. This can also be considered as logging out from the server.
