Instant messaging connects people wherever they are and allows them to communicate with others in real time. Agora offers an open-source Chat UI Kit project on GitHub. With built-in user interfaces for key Chat features, the Agora Chat UI Kit enables you to quickly embed real-time messaging into your app without requiring extra effort on the UI.

    1. Clients retrieve a token from your app server.
    2. Client A and Client B log in to Agora Chat.
    3. Client A sends a message to Client B. The message is sent to the Agora Chat server, and the server delivers the message to Client B. When Client B receives the message, the SDK triggers an event. Client B listens for the event and gets the message.
