Telegram node common issues

Here are some common errors and issues with the Telegram node and steps to resolve or troubleshoot them.

Add a bot to a Telegram channel

For a bot to send a message to a channel, you must add the bot to the channel. If you haven't added the bot to the channel, you'll see an error with a description like: Error: Forbidden: bot is not a participant of the channel.

To add a bot to a channel:

  1. In the Telegram app, access the target channel and select the channel name.
  2. Label the channel name as public channel .
  3. Select Administrators > Add Admin .
  4. Search for the bot's username and select it.
  5. Select the checkmark on the top-right corner to add the bot to the channel.

Get the Chat ID

You can only use @channelusername on public channels. To interact with a Telegram group, you need that group's Chat ID.

There are three ways to get that ID:

  1. From the Telegram Trigger: Use the Telegram Trigger node in your workflow to get a Chat ID. This node can trigger on different events and returns a Chat ID on successful execution.
  2. From your web browser: Open Telegram in a web browser and open the group chat. The group's Chat ID is the series of digits behind the letter "g." Prefix your group Chat ID with a - when you enter it in Automated Workflows.
  3. Invite Telegram's @RawDataBot {:target=_blank .external-link} to the group: Once you add it, the bot outputs a JSON file that includes a chat object. The id for that object is the group Chat ID. Then remove the RawDataBot from your group.

Send more than 30 messages per second

The Telegram API has a limitation{:target=_blank .external-link} of sending only 30 messages per second. Follow these steps to send more than 30 messages:

  1. Loop Over Items node : Use the Loop Over Items node to get at most 30 chat IDs from your database.
  2. Telegram node : Connect the Telegram node with the Loop Over Items node. Use the Expression Editor to select the Chat IDs from the Loop Over Items node.
  3. Code node : Connect the Code node with the Telegram node. Use the Code node to wait for a few seconds before fetching the next batch of chat IDs. Connect this node with the Loop Over Items node.

You can also use this workflow{:target=_blank .external-link}.

Remove the Automated Workflows attribution from sent messages

If you're using the node to send Telegram messages, the message automatically gets an Automated Workflows attribution appended to the end:

This message was sent automatically with Automated Workflows

To remove this attribution:

  1. In the node's Additional Fields section, select Add Field .
  2. Select Append Automated Workflows attribution .
  3. Turn the toggle off.
