Send Telegram Business msg in business mode

[Sprchrgd]

Telegram now allows to chat with users through regular chat, where bot is connected to business user with permissions to reply.

However, send string should contain business_connection_id.

This is what I have in Chat ID setting:
{{ $('Telegram Trigger').item.json.business_message.chat.id }}

And result is error: Forbidden: bot can’t initiate conversation with a user.

Maybe adding business_connection_id should help to avoid error as far as I’m googling.

Don’t know how to incorporate business_id into this expression.

hello @Sprchrgd

I suppose Telegram Node in n8n doesn’t have business API functionality. You can utilize the HTTP Requests Node, but that will be way more difficult

[Sprchrgd]

And unfortunately this is not in the roadmap either.

Can’t even add custom field. Such an easy feature to add.

To enable your bot to reply in private chats through a business connection in n8n, you must use the HTTP Request node to send requests to the Telegram API, specifying the business_connection_id parameter. This parameter is required to identify the business connection and facilitate sending messages in private chats.

Setup Steps:

1. Extract Necessary Data:

• From the JSON response received from Telegram, extract business_connection_id and chat.id.

2. Configure the HTTP Request node in n8n:

• Add the HTTP Request node to your workflow.
• Set the request method to POST.
• In the “URL” field, specify the Telegram API endpoint for sending messages:

https://api.telegram.org/bot<TOKEN>/sendMessage

replacing <TOKEN> with your bot’s actual token.

In the “Body Parameters” section, include these parameters:

chat_id: {{$json["business_message"]["chat"]["id"]}}
text: Your response message
business_connection_id: {{$json["business_message"]["business_connection_id"]}}

Example configuration of the HTTP Request node:
Method: POST
Body Parameters:

chat_id: {{$json["business_message"]["chat"]["id"]}}
text: Your reply to the incoming message
business_connection_id: {{$json["business_message"]["business_connection_id"]}}

Works flawlessly. Thank you Dimapo!

Hello.
I can’t replicate this with my parameters.
I’m not a coding expert. Could you please point out what I did wrong?
Error code 400
Bussines Mode - turn on
Privacy Mode - turn off

hello @Vladyslav_Nechyporen

• Body Content Type: JSON
• Specify Body: Using Fields Below

[Sprchrgd]

This is because you put your body content in the field called “Body Content Type”. Delete all this, select JSON in that field and then create 3 pairs of name/value parameters with the data (e.g. name=chat_id and value=your expression).
