Telegram client settings

To make telegram client working you should follow steps:

  • Be sure you set correct host in Redmine settings
  • Go to the plugin settings page

Create Telegram Bot

It is necessary to register a bot and get its token. There is a @BotFather bot used in Telegram for this purpose. Type /start to get a complete list of available commands.

Type /newbot command to register a new bot. @BotFather will ask you to name the new bot. The bot's name must end with the "bot" word. On success @BotFather will give you a token for your new bot and a link so you could quickly add the bot to the contact list. You'll have to come up with a new name if registration fails.

Set the Privacy mode to disabled with /setprivacy. This will let the bot listen to all group chats and write its logs to Redmine chat archive.

Set bot domain with /setdomain for account connection via Telegram Login. Otherwise, you will receive Bot domain invalid error on account connection page.

Enter the bot's token on the Plugin Settings page to add the bot to your chat.

To add hints for commands for the bot, use command /setcommands. You need to send list of commands with descriptions. You can get this list from command /help.
