Step 1: Create a Telegram bot
You create Telegram bots through a special Telegram account called @BotFather.Open BotFather
In Telegram, search for @BotFather (the verified account with a blue checkmark) and start a conversation.
Set your bot's display name
When asked “Alright, a new bot. How are we going to call it?”, type a friendly name for your bot. This is the name users will see in chats, for example:
Set your bot's username
When asked for a username, type a unique handle ending in The username must be unique across all of Telegram. If it is already taken, try adding your company name or a number.
bot, for example:Copy your bot token
BotFather will confirm the bot is created and show a message like:
Done! Congratulations on your new bot. You will find it at t.me/HellenicAssistantBot. You can now add a description…
Use this token to access the HTTP API:
123456789:ABCdefGHIjklMNOpqrsTUVwxyz
Copy the token — you will need it in the next step.Step 2: Connect to hellenicAI Assistants
Go to your instance dashboard
Log in at app.hellenicai.com and open your instance.
Step 3: Approve your Telegram account
After saving the token, you need to complete a one-time pairing step to link your personal Telegram account to the bot. This is a security measure to ensure only authorised users can chat with your assistant.Open your bot in Telegram
On your phone or desktop, search for your bot by username (for example
@HellenicAssistantBot) and tap Start.Receive your pairing code
The bot will send you a message like this:Copy the 8-character pairing code (for example
GC5CC9FK).Paste the code in your dashboard
Back in the hellenicAI Assistants dashboard, a Step 2 panel will have appeared below the Telegram token field. Paste your pairing code into the input and click Approve.
Each Telegram user who wants to chat with the assistant needs to complete this pairing step once. If you need to link a different account, click Re-pair next to the Paired badge and repeat the process.
Step 4: Test the connection
Send a message
In the Telegram chat with your bot, type any question, for example: “What can you help me with?”
Troubleshooting
| Problem | Solution |
|---|---|
| Bot sends a pairing code but the Step 2 panel is not visible | Refresh the dashboard page and scroll down to the Channels section |
| Pairing code is rejected | Make sure you are entering the code exactly as shown, without spaces. Codes are 8 characters and contain only letters and numbers |
| Status shows Connected but not Paired | Complete Step 3 above to approve your Telegram account |
| No reply from bot after pairing | Verify the bot token was saved correctly and that the status shows Paired, not just Connected |
| Want to let another team member use the bot | Each user must open the bot in their own Telegram account, receive their pairing code, and enter it in the dashboard |
| ”Unauthorised” error in dashboard | The token may be incorrect. Regenerate it in BotFather with /revoke and reconnect |
| Bot replies but answers seem off | Check the AI model selected in your instance settings |
