Send a Welcome Message in a Microsoft Teams Notification Bot

In this blog, we'll discuss how to send a welcome message when a Microsoft Teams notification bot, built with Azure Functions (HTTP trigger) using JavaScript, is added to a chat or channel. By leveraging the conversationUpdate event and integrating it into the Azure Functions workflow, you can automate the delivery of a welcome message every time your bot is introduced to a new conversation.

Here’s how to integrate this functionality into your Azure Function-based bot.

Overview

In this setup, you’re likely using an Azure HTTP-triggered function to manage notifications, and you want the bot to automatically send a welcome message when added to a Microsoft Teams chat or channel.

How Does It Work?

• Bot Initialization: The bot is deployed using Azure Functions, with a specific URL endpoint for triggering actions.
• Handling conversationUpdate Event: The bot receives an event when it is added to a conversation. We can use this event to trigger a welcome message.
• Sending Welcome Message: The bot replies with a message that includes details such as the conversation type, ID, and the bot's HTTP endpoint.
