This page demonstrates how to install the Chat SDK in your app so that you can send your first message in just a few simple steps. In addition, try building your app on top of our sample app to jumpstart your build.
Note: To learn about how to build a chat app using React Native and Hooks, see our React Native chat tutorial.

Note: Sendbird server supports Transport Layer Security (TLS) from version 1.0 up to 1.3. For example, in the server regions where TLS 1.3 isn’t available, lower versions, sequentially from 1.2 to 1.0, will be supported for secure data transmission.
Before installing Sendbird Chat SDK, you need to create a Sendbird application on the Sendbird Dashboard, which comprises everything required in a chat service including users, messages, and channels. You will need the
App ID of your Sendbird application when initializing the Chat SDK.
Note: Each Sendbird application can be integrated with a single client app. Within the same application, users can communicate with each other across all platforms, whether they are on mobile devices or on the web.
UIKit is a Sendbird Chat SDK add-on with user interfaces that enable an easy and fast integration of standard chat features into new or existing client apps.
If you would like a sample app with embedded UIs, see UIKit Quickstart for React.
To send a message in a client app, you should build and configure an in-app chat using Sendbird Chat SDK. Sendbird Chat SDK can be installed through either a web sample project or React Native project.
Installing Sendbird Chat SDK is simple if you’re familiar with using external libraries or SDK’s in your projects. You can install the Chat SDK with npm using the following command.
lib/ directory), and then include the Chat SDK file to your working file.
App ID, which can be found on the Sendbird Dashboard.
With local caching, a new optional parameter has been added to the
SendBird() method, which is
localCacheEnabled determines whether the client app will use the local storage through Sendbird Chat SDK or not. Because this is optional, the default value will be false. If you want to build a client app with our local caching functionalities, set the
localCacheEnabled to true.
You will need a user in order to send a message to a channel. You can either create a user on our dashboard or use a unique ID that hasn't been taken by any of your Sendbird application users. In the latter case, a new user will be automatically created in your Sendbird application before being connected.
Note: To learn more about authenticating with an access token, go to Authentication.
Create an open channel. Open channels are where all users in your Sendbird application can easily participate without an invitation.
The following codes show how to create an open channel.
Note: You can also create a group channel to send a message. To learn more, see Create a channel in the Group channel page.
Enter the open channel to send and receive messages.
Finally, send a message to the channel. To learn more about the message type you can send, see Message.
onMessageReceived() channel event handler using the
addChannelHandler() method so that you can receive the message you just sent to the channel. You can also see the message on our dashboard.
