Overview

Learn how to initialize the Advanced iMessage Kit SDK and perform basic operations like sending messages and listening for incoming messages.

​
Sending a Message

The simplest way to send a message is to initialize the SDK, wait for the ready event, and use the sendMessage method. 
import { createSDK, handleError } from "./utils";

const CHAT_GUID = process.env.CHAT_GUID || "any;-;+1234567890";

async function main() {
    const sdk = createSDK();

    sdk.on("ready", async () => {
        try {
            const message = await sdk.messages.sendMessage({
                chatGuid: CHAT_GUID,
                message: "Hello from MOBAI!",
            });

            console.log(`sent: ${message.guid}`);
            console.log(`${new Date(message.dateCreated).toLocaleString()}`);
        } catch (error) {
            handleError(error, "Failed to send message");
        }

        await sdk.close();
        process.exit(0);
    });

    await sdk.connect();
}

main().catch(console.error);

​
Key Points

  • Initialize the SDK with createSDK()
  • Wait for the ready event before performing operations
  • Use chatGuid to specify which conversation to send to
  • The returned message object contains metadata like guid and dateCreated
  • Always close the SDK connection when done

​
Listening for Messages

To build a message listener that handles incoming messages in real-time: 
import { getPollSummary, isPollMessage } from "../lib/poll-utils";
import { createSDK, handleExit } from "./utils";

async function main() {
    const sdk = createSDK();

    sdk.on("ready", () => {
        console.log("ready");
    });

    sdk.on("new-message", (message) => {
        const sender = message.handle?.address ?? "unknown";

        if (isPollMessage(message)) {
            const pollSummary = getPollSummary(message);
            console.log(`\n${sender}: ${pollSummary}`);
        } else {
            console.log(`\n${sender}: ${message.text ?? "(no text)"}`);
        }
    });

    sdk.on("updated-message", (message) => {
        const status = message.dateRead ? "read" : message.dateDelivered ? "delivered" : "sent";
        console.log(status);
    });

    sdk.on("error", (error) => {
        console.error("error:", error.message);
    });

    await sdk.connect();
    handleExit(sdk);
}

main().catch(console.error);

​
Event Handlers

Fired when a new message is received. The message object contains:
  • handle.address - Sender’s phone number or email
  • text - Message text content
  • isFromMe - Boolean indicating if you sent the message
Fired when a message status changes (delivered, read, etc.):
  • dateRead - Timestamp when message was read
  • dateDelivered - Timestamp when message was delivered
  • dateSent - Timestamp when message was sent
Handles SDK errors. Always implement this handler for production apps.

​
Getting Chat GUIDs

To find a chat GUID for sending messages, you can list all your chats: 
const chats = await sdk.chats.getChats();
chats.forEach(chat => {
    console.log(`${chat.displayName}: ${chat.guid}`);
});
For phone numbers, the chat GUID format is typically any;-;+1234567890
