You can use your Telegram messenger as a notification tool to get instant reports on various infrastructure events, script execution results, or scheduler tasks. This article shows you how to use PowerShell to send a text notification to a Telegram channel or group through the Bot API.<\/p>\n<\/p>\n
First, create a new Telegram bot using Specify the bot\u2019s name and username. BotFather will generate an HTTP token that you must copy and save.<\/p>\n<\/p>\n To send a message to a Telegram chat or a specific user, you need to know their ID. In this example, I will send notifications to myself, so use To send a message to any Telegram chat, you will need to designate the bot token as well as the ID of your intended user (or conversation):<\/p>\n<\/p>\n Connection to the Telegram API necessitates the TLS 1.2 protocol. Make sure to enable the version of the TLS 1.2 protocol<\/a> in Windows. Ordinarily, PowerShell establishes connections using the aged SSL 3.0, TLS 1.0, or TLS 1.1 protocols. Execute the command shown below to engage the TLS version 1.2 within the current PowerShell session:<\/p>\n<\/p>\n And here\u2019s a command to send a message to Telegram:<\/p>\n<\/p>\n Once you run that one, you should get a message from the bot.<\/p>\n<\/p>\n You can use emoji and HTML text formatting to make notifications more visually appealing and readable:<\/p>\n<\/p>\n To work with PowerShell scripts, I recommend using the VS Code editor.<\/p>\n<\/p>\n If you are accessing the Internet through a proxy server, you can use the <code>-Proxy<\/code> parameter of the Invoke-WebRequest cmdlet<\/a> to specify the proxy settings. Use the <code>-ProxyCredential<\/code> argument to authenticate to a proxy.<\/p>\n<\/p>\n In version PowerShell Core 7.x<\/a>+, the Invoke-WebRequest cmdlet uses the proxy settings specified in the environment variables.

Find it in your Telegram client and send it the following commands:<\/p>\n<\/p>\n\/start<\/code>\/newbot<\/code><\/p>\n<\/p>\n@my_id_bot<\/code> to find my Telegram ID:<\/p>\n\/start<\/code><\/p>\nYour user ID: 987654321<\/pre>\n<\/p>\n
