A Telegram chatbot powered by the ChatGPT API routes messages from Telegram to the OpenAI API and sends the response back to the user, all in real time. You need two API connections: the Telegram Bot API (via python-telegram-bot or a webhook) and the OpenAI API (via the official Python SDK). At aidowith.me, the Telegram Bot route covers 14 steps in about 3 hours. You'll write the Python handler with AI assistance, configure the system prompt that defines the chatbot's behavior, handle conversation history so the bot remembers context within a session, and deploy to a server with a public URL for Telegram's webhook. The route covers rate limiting, error handling for API timeouts, and a basic logging setup so you can monitor what questions users are asking. By the end, you'll have a live, conversation-aware chatbot deployed to a real URL.

The Problem and the Fix
Without a route
- You get the bot responding to messages but it has no memory: every reply ignores the previous message in the conversation
- Telegram webhook setup is confusing: you set it but Telegram shows 'webhook not set' and you don't know why
- Your bot works in testing but crashes on the first production message because of unhandled API timeout errors
With aidowith.me
- Build a Telegram chatbot with conversation memory using a session history implementation that costs nothing extra
- Configure and verify the Telegram webhook in under 10 minutes with a step-by-step verification check
- Add error handling for OpenAI API timeouts and rate limits so the bot sends a fallback message instead of crashing

How It Works
Get API tokens and set up the project
Create the Telegram bot via BotFather, get the OpenAI API key, and set up a Python virtual environment. AI generates the requirements.txt and project structure. 20 minutes total.
Write the message handler with conversation history
AI generates the Python handler that stores per-user conversation history and passes it with each OpenAI API call. You'll test locally with the polling mode before moving to webhooks.
Configure webhooks, error handling, and deploy
Switch from polling to webhook mode, set up the public URL using Render or Railway, and verify the webhook registration. Add try/except blocks for API errors. Deploy and test with 5 real messages.

Questions
Create a Telegram bot with BotFather, set up an OpenAI API key, write a Python handler that routes Telegram messages to the OpenAI API, and deploy with webhook support. The aidowith.me Telegram Bot route covers all 14 steps in about 3 hours, including conversation history, webhook setup, and error handling.
Store each user's message history in a Python dictionary keyed by their Telegram user ID. Pass the last 5-10 messages as context with each new OpenAI API call. The route shows you exactly how to implement this, how to cap history length to control token costs, and how to reset history when a new conversation topic starts.
The 3 most common causes: the webhook URL doesn't have a valid SSL certificate, the URL isn't publicly accessible (localhost won't work), or you haven't called setWebhook correctly after deploying. The route includes a verification step that checks all three and gives you a curl command to confirm the webhook is registered properly.
