Solved: Telegram Trigger configuration

[RichardC]

Today I stumbled through configuring my Telegram Trigger in n8n. I saw a lot of questions on this forum, so I thought I’d post what worked for me. In addition to the standard instructions I also needed to to this:

1. Set the webhook:
   • Use Postman to POST to https://api.telegram.org/bot<YOUR_BOT_TOKEN>/setWebhook
     Under Body, choose form-data and create a key:value pair of:
     url:<YOUR N8N WEBHOOK>
   • Check the webhook with POST https://api.telegram.org/bot<YOUR_BOT_TOKEN>/setWebhook (and no body)

[After doing that, I accidentally discovered that posting ‘test’ to the group would not trigger anything, but posting ‘/test’ (or anything that starts with ‘/’) would trigger n8n. So I did the next two items.]

2. Privacy Mode:

   • Disable privacy mode:
     • Open a chat with BotFather.
     • Send the command /mybots to see a list of your bots.
     • Select your bot and use the command Edit Bot Privacy to turn off privacy mode.

3. Group Admin:

   • Ensure that your bot is an admin in the group chat. For the bot to receive all messages in a group, it typically needs to have admin permissions.

Now Telegram triggers instantly. Hope this helps someone.
