This is a simple API Gateway that allows you to configure a Telegram webhook destination in a New Relic Workflow to send alerts to a Telegram channel or group.

I took the basis for this project here - jdezego/new-relic-telegram-alerts.

You must first create a Telegram Bot and add it to your channel/group as an admin: https://core.telegram.org/bots/tutorial

• Create a Telegram channel or group
• Contact @BotFather to create a new bot and follow the instructions
• Follow instructions to create a new bot
• Note bot API key
• Add the created bot to the channel/group and enable sending messages

Get chat id for group or channel. Must already have messages in group/channel or this returns empty array: https://api.telegram.org/bot[BOT_API_KEY]/getUpdates

Send message to bot using chat id: https://api.telegram.org/bot[BOT_API_KEY]/sendMessage?chat_id=[CHAT_ID]&text=[MESSAGE]

In order to run the project in the console, enter:

node index.js

To send a message (locally), you need to make a POST request to 127.0.0.1:3000. In body, pass json from example. It is also necessary to add Headers to the request:

apikey: [YOUR BOT API KEY]
chatid: [YOUR CHAT ID]
