How to Send Alerts from Amibroker to Telegram Channel using Telgram API

In this tutorial we will be discussing practical examples of how to send alerts from Amibroker to a Telegram channel using Telegram Bot API

In order to be able to do so, you will have first to:

• Create a Telegram public channel
• Create a Telegram BOT via BotFather
• Set the bot as administrator in your channel

Getting the BOT API key from BotFather in Telgram APP

Provided that you did the above, now you can send a message to your channel by issuing an HTTP GET request to the Telegram BOT API at the following URL:

where:

• BOT_API_KEY is the API Key generated by BotFather when you created your bot
• MY_CHANNEL_NAME is the handle of your channel (e.g. @my_channel_name)
• MY_MESSAGE_TEXT is the message you want to send (URL-encoded)
