I am able to send message to specific users with older botbuilder SDK 3.13.1 by saving message.address field in database.
var connector = new builder.ChatConnector({
appId: process.env.MicrosoftAppId,
appPassword: process.env.MicrosoftAppPassword,
openIdMetadata: process.env.BotOpenIdMetadata
});
var bot = new builder.UniversalBot(connector);
var builder = require('botbuilder');
var msg = new builder.Message().address(msgAddress);
msg.text('Hello, this is a notification');
bot.send(msg);
How can this be done with botbuilder SDK 4? I am aware of the Rest API but want to achieve this with the SDK itself because the SDK is the more preferred way of communication between the bot and user.
Thanks in advance.

Proactive Messages in the BotFramework v4 SDK enable you to continue conversations with individual users or send them notifications.
First, you need to import TurnContext
from the botbuilder
library so you can get the conversation reference.
const { TurnContext } = require('botbuilder');
Then, in the onTurn
method, you can call the getConversationReference
method from TurnContext
and save the resulting reference in a database.
/**
* @param {TurnContext} turnContext A TurnContext object representing an incoming message to be handled by the bot.
*/
async onTurn(turnContext) {
...
const reference = TurnContext.getConversationReference(turnContext.activity);
//TODO: Save reference to your database
...
}
Finally, you can retrieve the reference from the database and call the continueConversation
method from the adapter to send specific users a message or notification.
await this.adapter.continueConversation(reference, async (proactiveTurnContext) => {
await proactiveTurnContext.sendActivity('Hello, this is a notification')
});
For more information about proactive messages, take a look at the documentation or this example on GitHub. Hope this is helpful.
